Hi, I require some help in finding dominating color in an image can u suggest some idea, i tried with histogram extraction and no idea how to find the dominant color in the histogram.
First you need to define what differentiates one color from another. Where exactly does "red" end and "purple" begin?
Take a look at the "color frequency image" in this link: http://www.mathworks.com/matlabcentral/fileexchange/28164-color-frequency-image You can probably adapt the code to handle different bin sizes. You question is exactly what the color frequency image is designed for. If you have any questions about how it operates, ask me - I understand the concepts in it.
