hey, I have a RGB image (attached). I need to crop the region that has color only, and remove the bright surrounding part. for this reason I used threshold (pixel value= 215) as follows, however this results in a vector which is not desired. I need the color region to be remained as an new RGB image...
original= imread('filename'); original= original(original<215);

Since the regions may not be rectangular, which is required for a crop, you'll have to mask the areas. See my File Exchange for several color segmentation demos that can do that: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

Attached are three masking demos.
