An Image Search Toolkit based on OpenCV's histogram comparison methods:

• cv2.cv.CV_COMP_CORREL: Computes the correlation between the two histograms.
• cv2.cv.CV_COMP_CHISQR: Applies the Chi-Squared distance to the histograms.
• cv2.cv.CV_COMP_INTERSECT: Calculates the intersection between two histograms.
• cv2.cv.CV_COMP_BHATTACHARYYA: Bhattacharyya / Hellinger distance, used to measure the “overlap” between the two histograms.
