### Use a image in every group as query image, search the dataset and get the score , The image dataset has 56 groups , every group has 4 images.SO, We will see if the retrieved top 4 images is this 4 images, so the possible score is 1,2,3,4.
### Test It! (with different resize scale factor)
g++ -std=c++11 -c orb.cpp `pkg-config opencv --cflags --libs`
g++ -o search main.cpp orb.o `pkg-config opencv --cflags --libs`
./search
### Test Results:
