color recognition methods(kmeans and hsv)

Color Recognition

This repo contains Kmeans and HSV pixel range Color Recognition methods.

Kmeans

to cluster domianant color of a given box, input is box coordinate(x,y,w,h), return is color name

Advantage: accurate

Disadvantage: Time-consuming

Reference: K-Means Clustering in OpenCV

HSV pixel range

set up a HSV color look up table first. then compare each pixel of roi image with the look up table, then the largest distribution of color is the dominant.
