This document discusses finding the dominant color in an artistic painting using data mining techniques. It proposes using k-means clustering via the OpenCV library in Python to cluster pixels in the image by color and determine the dominant color cluster. The document provides background on k-means clustering and other clustering algorithms. It then describes applying a faster k-means algorithm to the image pixels to efficiently identify the dominant color in 2-3 times fewer iterations than standard k-means. The proposed system architecture involves preprocessing the image, extracting pixel vectors, clustering the pixels into color groups using fast k-means, and identifying the dominant color cluster.
