Researchers from a variety of fields have been motivated by the success of CNNs in computer vision to develop better CNN models for use in other visually-rich settings. Successes in image classification and research have been achieved in a wide variety of domains throughout the past year. Among the many popularized image classification techniques, the detection of plant leaf diseases has received extensive research. As a result of the nature of the procedure, image quality is often degraded and distortions are introduced during the capturing of the image. In this study, we look into how various CNN models are affected by distortions. Corn-maze leaf photos from the 4,188-image corn or maize leaf Dataset (split into four categories) are under consideration. To evaluate how well they handle noise and blur, researchers have deployed pre-trained deep CNN models like visual geometry group (VGG), InceptionV3, ResNet50, and EfficientNetB0. Classification accuracy and metrics like as recall and f1-score are used to evaluate CNN performance.

INTRODUCTION Agriculture is the mainstay for both the economy and survival. Currently, the growth rate of agriculture production has been decreasing due to various diseases in plants because of weather conditions, global warming, and pollution. Plant diseases mainly affect the quality and it is indeed a challenging task. With farmers making rough measurements manually, results may not be efficient and are time-consuming. Digital agriculture is the concept to use new and advanced technologies, consolidated in one system that enables farmers to improve the quality and production of food [1]. Digital process accumulate data periodically and accurately, usually combined with a few external sources like weather information. The resulting data is examined and depicted so the farmer can make decisions with high accuracy. To get accurate output, new automatic approaches are introduced such as sensors, unmanned aviation systems (UAS), robotics, artificial intelligence (AI), and other computational approaches. These approaches enable the farmers to reduce cost and time. Thus, moving for rapid, economical, precise, and computerized methods to identify diseases in plants is very crucial. Computer vision has developed thoroughly in the agriculture industry with the capability to process multimedia information in the form of images [2]. The detection can be done by machine learning (ML) approach or deep learning (DL). The ML system is made up of two parts: a feature extraction module that pulls out relevant details like edges and textures, and a classification module that assigns labels to those details. The fundamental drawback of ML is

Fortunately, this shortcoming is corrected by utilizing DL. A subfield of ML, DL uses its own special kind of computation to learn. As an alternative to the haphazard way in which humans make judgments, a DL model is provided to consistently deconstruct information with a uniform structure [3]. To do this, DL employs an artificial neural system expressed as a layered structure comprising many algorithms artificial neural network (ANN) [4]. The human brain's biological neural network is used as a model to simulate an ANN's design. Because of this, DL has proven to be more effective than other types of ML. Therefore, in this work, DL was utilized for the aim of detection. Image acquisition, preprocessing, segmentation, feature extraction, and classification are the several phases involved in the process of detecting plant diseases. The process of classifying plant diseases requires making educated guesses about the category or label. The first step in the classification process involves placing photos into one of several predetermined categories. Because image processing is one of the most quickly developing technologies, the process of image capture is frequently accompanied by a number of different types of distortions throughout the process of image acquisition [5]. For instance, when we process image acquisition, there is a possibility that it will add some form of blur or distortion to the image. In the course of this line of research, we are attempting to determine the impact that image distortions have on convolutional neural network (CNN)-based image classifiers. Image blurring, image noise (also known as independent noise or spike noise), Poisson noise (also known as shot noise), and numerous types of image blurring include the following: motion blur, average blur, Gaussian blur, out-of-focus blur, and atmospheric turbulence blur [6], [7]. Numerous earlier study papers have been published to review agricultural research, including the detection of plant diseases using DL or ML [8], [9] but they lacked some of the most recent developments in visualization methods for plant disease diagnosis. To the best of the author's knowledge, distortions that happen during classification have not been considered by any researchers, despite the fact that these distortions may cause variations in the results. As a result, the motivation behind the proposed work is to find out how well CNN models perform when distortions are present. In this study, two different kinds of picture distortions, namely Gaussian blur and salt and pepper noise, have been investigated to determine the impact that each type of distortion has on CNN-based image classifiers. The performance of pre-trained CNNs is evaluated using a dataset of plant diseases and is compared to how well they function when subjected to the influence of Gaussian blur and salt and pepper noise, respectively. Thus, the main objective of this study is to find the robustness of various CNN’s model against distortions. The remainder of the paper is divided into the following sections: in section 2, the findings of previous studies are summarized. Section 3 provides a method for the proposed work. In section 4, the results and evaluation are discussed. The conclusions from the study are summarized in section 5. 2. RELATED WORK The literature presented in this section covers extensive research and provides an idea of the work accomplished through deep models. In the wake of Table 1, bring to a close the investigation of the history of work concerning the categorization and identification of plant diseases. CNNs model was used to classify diseases in rice plants with a dataset of nearly 500 naturally collected images of both healthy and unhealthy rice leaves and was compared with support vector machine (SVM), back propagation, and particle swarm optimization algorithm [10]. The dataset included images of both healthy and unhealthy rice leaves. An algorithm for the diagnosis of diseases was developed and implemented by [11]. Image processing and artificial neural algorithms were utilized by the author in order to determine whether or not the brinjal leaf was infected. The k-means approach was used for the segmentation of the images, and then neural networks were used for the classification. Maeda-Gutiérrez et al. [12] focused on a comparative study of various CNN models (AlexNet, GoogleNet, Inception V3, ResNet 18, and ResNet 50) using the PlantVillage dataset consisting of nine classes to analyze tomato leaves. The tomato disease detection method, which was developed by Wang et al. [13] and was based on a deep CNN and an object detection model, was successfully implemented. Both faster region-based CNN (R-CNN) and mask R-CNN were utilized in this process. In order to determine which model is best suited for the detection of tomato disease, the author conducted an analysis that combined two different object detection models with four distinct deep CNN. Image recognition of apple diseases was accomplished by Chuanlei et al. [14] using region growing algorithm (RGA), genetic algorithm and correlation-based feature selection (GA-CFS), and SVM. The image recognition was based on the colour, shape, and texture features that were extracted from the affected leaf images. The apple leaves that are afflicted with diseases are the primary topic of investigation in this study. The author took into consideration a total of 38 image features, including 14 colour features, 4 shape features, and 20 texture features. These image features are extracted from each segmented spot image, and they are

Research by Ferentinos [15] used CNN models AlexNet, AlexNetOWTBn, GoogLeNet, and visual geometry group (VGG) on a publicly accessible database of 25 different plant species. They were able to achieve an accuracy of 99.53% success rate through the use of these models. Research by Mahajan et al. [16] proposed a DL model called DL-based haze perceptual quality evaluator (DLHPQE) for predicting image quality in hazy conditions. This model is used to estimate the effect of an environmental factor known as haze on image quality. Research by Rahman et al. [17] has contributed large- scale architectures such as InceptionV3 and VGG16 for the purpose of detecting and identifying rice diseases. These have been compared with two-stage small CNN architectures such as MobileNet, SqueezeNet, and NasNet mobile. Data was collected in a real-world setting from paddy fields at the Bangladesh rice research institute (BRRI), which comprises eight distinct classes. On the UC Merced land use aerial dataset, the performance of the AlexNet and GoogleNet architectures was analyzed and compared in [18], taking into account the influence of Gaussian blur. Results that have been compiled investigated the resistance of CNN's model towards blur. As a result of GoogleNet's greater adaptability to a wide range of Gaussian blurring levels than AlexNet's, the research presented in the literature demonstrated the applicability of CNNs to a wide variety of domains and scenarios. The purpose of this paper is to conduct an analysis of how CNNs actually work in practice with regard to image distortions. The dataset is improved by including some salt-and-pepper noise as well as some Gaussian blurring. This paper makes a contribution by demonstrating the impact of the blurring effect and noise effect on the classification performance of CNNs. Table 1.

METHOD The DL is currently generating a revolution in a wide range of industries, from robots to medicine and everything in between [20]. CNN are among the DL models that can automatically learn spatial feature hierarchies. These networks are able to handle grid pattern data in a similar manner to how a photo is handled. We will look into the suggested technique for our study in this part. The basic method for using CNN models to identify the presence of plant leaf diseases is shown in Figure 1. The PlantVillage dataset's secondary data were first gathered as a preliminary step. Following that, the data was subjected to distortions like blur and noise so that it could be investigated to determine how they influenced the detection of plant leaf diseases. Although there are many different types of noise and blur distortions, this study has used salt-and-pepper noise and randomly generated Gaussian noise. Some other distortions that are already present may be taken into account by researchers in the future. The blurring is done by applying the gaussian function, which is given by the equation in the equation box below. It accomplishes this by averaging the values of the pixels that are directly surrounding the one in question [19]. The equation that requires solving is as (1): 𝐺(𝑥, 𝑦) = 1 2𝜋𝜎2 𝑒−(𝑥2+𝑦2) 2𝜎2 ⁄ (1) here 𝜎 represents blur factor, e represents euler number, and (𝑥, 𝑦) represents horizontal and vertical distance with respect to center pixel. Similarly, noise is introduced into dataset by applying salt and pepper noise expressed as (2):

Also, 𝑎 and 𝑏 represent noise impulses; for 𝑏 > 𝑎, intensity 𝑏 appears to be a light point, while 𝑎 pitch appears as a dark point on the image [27]. The following data pre-processing is done to change the photos' shape and scale them to 150×150×3. In accordance with this, the data is enhanced by shearing and zooming with a value of 0.2. CNN models are then fed the augmented data (both with and without distortions). The ResNet50, VGG16, VGG19, InceptionV3, and EfficientNetB0 pre-trained CNN models are used [15]. These are pre-trained CNN models that were trained using the more than 20,000 classes and over 14 million images in the ImageNet dataset. Microsoft's ResNet50 [20] model accepts more than a million 224×224-pixel pictures as input. VGG models accept photos with 3 channels and 224×224-pixel input sizes. The input size for InceptionV3 is 299×299 pixels, and it contains 48 deep layers [21]. EfficientNet [22], a different pre-trained model, has eight alternative implementations (B0 to B7). With 5.3 million parameters, EfficientNetB0 is the most basic and performs best in terms of top-1 accuracy. These models are summarised in Table 2. The models include a variety of layers, including fully linked, pooling, and convolutional layers. The convolutional layer uses image pixels from the plant leaf database to perform convolution operations and produce convolution maps. The convolved map is subjected to the activation function, similar to rectified linear unit (ReLU), to create a rectified feature map. For the purpose of identifying the prominent characteristics, the image is processed using different convolutions and ReLU layers. To identify certain areas of an image, distinct pooling layers with various filters are used. In order to classify the type of plant leaf disease, the output of the pooling layer is flattened and provided as input to a fully connected layer. As CNNs are implicitly present during the feature extraction process, the features are extracted layer by layer. The many filters of an individual DL model's activation maps are shown in Figure 2, which visualises the activation maps from various convolution layers, activating various elements of an image, such as the background, edges, and outer border. As a result, more features are abstracted from an image as it moves through deeper layers, which helps with correct classification. Figure 1.

These include the typical grey leaf spots, common rust, and blight. The corn or maize leaf dataset [32], which comprises corn or maize leaf, was used to collect the data for this study. Table 3 lists the number of classes and the images that are included in each class. The input images have been resized with 150 as the height and width before being used for classification. Figure 3 depicts an example of a diseased corn or maize leaf, with Figure 3(a) showing corn leaves affected by blight, Figure 3(b) showing leaves affected by grey leaf spot, and Figure 3(c) showing leaves affected by common rust. The 80% of image data was used for training, while the remaining 20% was used for testing. To measure the consequences of these distortions, we blurred and distorted clear images using Gaussian and salt- and-pepper noise, respectively. The sample of original photos and distorted images is shown in Figure 4, where Figure 4(a) depicts original images, or images without distortions, Figure 4(b) depicts leaf images with salt-and-pepper noise, and Figure 4(c) depicts leaf images with Gaussian blur.

Observations To attain the highest accuracy, 100 epochs of both distorted and undistorted data were used to implement all of the aforementioned models. Different training-validation plot curves were generated for each model, and EfficientNetB0, which has a validation accuracy of over 90%, is the most accurate model. The training and validation accuracy of the implemented EfficientNetB0 model are presented in Figure 5, both without distortions (in Figure 5(a)) and with distortions (in Figures 5(b) and 5(c)). Similarly, all of the aforementioned CNN models have been used and vary in accuracy from 70 to 95%. Table 4 provides a summary of the changes in validation accuracy based on image distortions. According to this result, the performance of CNN's model varies in response to distortions. The graphs shown in Figure 6 help to visualize comparisons between implemented CNN pre-trained models on the basis of accuracy. Figure 6(a) shows the model's accuracy on the original data, whereas Figure 6(b) shows its accuracy on distorted data. According to the performance of CNN models, the predicted values i.e., class labels are validated and confusion matrices were generated giving us count of TP, TN, FP, and FN, respectively. Figure 7 shows the generated confusion matrix, describing the performance of pre-trained implemented CNN architecture for VGG19 as an example, where Figure 7(a) representing the generated confusion matrix of original data, Figures 7(b) and (c) depicting the confusion matrix of noise-distorted and blur-distorted data.

It gives a probability curve that assesses the performance of classification models. A higher ROC indicates the superiority of the classification model [30]. Figures 8(a)-(c) and 9(a)-(c) show the best and the worst ROC curves given by the CNN models, respectively. InceptionV3 performed admirably, with area under the curve (AUC) values of 0.97, 0.96, and 0.96 for original, noisy, and blurred images, respectively. ResNet50, on the other hand, deprived low values, i.e., 0.75, 0.5, and 0.5 for original, noisy, and blurred images, respectively. For models with an AUC value between 0.5 and 1, there is a high possibility that the classifier will actually want to recognize the positive class values from the negative class values. Through various graphs and performance metrics, we could infer ResNet50 underperforms with an accuracy of 70.02% and low classification metrics compared to others. Further, ResNet50 does not classify distorted images accurately, whereas the EfficientNetB0 and InceptionV3 models achieved much better accuracy with fewer parameters compared to ResNet. Parallelly, it classified distorted images with better performance metrics, meaning the influence of distortions does not affect the classification process. Other models, such as VGG16 and VGG19, also demonstrated comparable performance. We compared our approach to other comparable case studies involving different types of leave, as shown in Table 6, and concluded that it performed better, with an accuracy rate of 92%.

CONCLUSION In this work, pretrained DL models were implemented for plant leaf disease detection and compared various CNN architectures with the original images and distorted images to determine the influence of distortions like blur and noise. Particularly, the ResNet50, VGG16, VGG19, InceptionV3, and EfficientNetB0 models were trained on the corn-maize leaf dataset, which consists of 4188 total images with four classes. In comparison, the ResNet50 model performed poorly due to the effects of distortions. In terms of model accuracy, however, EfficientNetB0 outperforms the implemented CNN models, both with and without distortions. InceptionV3 has also performed significantly better in terms of its capacity to recognise positive and negative classes compared to others. REFERENCES [1] V. Singh and A. K.
