MATLAB: I have to apply segmentation on color image of banana

Question

I have to remove background from banana in color form. which is the best way? and how to apply it? i mean code of segmentation with little explanation.

Answer 1

Since the background is neutral colored, I'd probably convert to hsv color space

hsv = rgb2hsv(rgbImage);

and then threshold the S channel

background = hsv(:,:,2) < 0.2; % Or whatever value works.

After that it depends on what your mathematical definition of "remove" means. Do you mean to make it pure black? Do you want to crop for some reason? What do you need to do?

See my File Exchange for full blown demos on hsv color segmentation: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
