K-MEANS WITH SAMPLING FOR DETERMINING PROMINENT COLORS IN IMAGES
A tool that quickly calculates the dominant colors of an image can be very useful in image processing. The k-means clustering algorithm has this potential since it partitions a set of data into n clusters and returns a representative data point from each
