How Do I trace? or track? the brown color of the hand of the image? which is capture during the snapshot and my background is white? then crop automatically the hand? I am currently doing Hand Signal Recognition..I get a program from my friend but a little bit confusing how to configure the code since my background is white and his background is blue i guess...see this link for the image

This is the Code I got from my old friend, can you help how to configure those code? if would be okay?
asdfg_count = 0;

%special part convert blue to white (bg)
image_size = size(orange);
a1 = image_size(1,1);

for aa1=1:a1,

%track blue

I don't have time to do private consulting on this. You can check my File Exchange for color segmentation demos. If you have a specific problem, such as an error message, then post it and someone will help you. But I don't have the time to spend hours adapting someone's code to your specific image, especially code with virtually no comments and confusing variable names. Sorry.
