how to save the segmented region as a separate image?

I have used the code which I have found in online and divided an image into several segments. I want to extract green parts from the image and store them. I am able to display the segmented image separately with black mask. but I want to display and save the green small segmented region only as a separate image (like 9 separate .jpg images ) without black regions.
This is the code I have found in online
segmented_images = cell(1,3);
rgb_label = repmat(pixel_labels,[1 1 3]);
for k = 1:nColors
color = img;
color(rgb_label ~= k) = 0;
segmented_images{k} = color;
end
Thank you in advance.

First get the outline, then the bounding box and use imcrop(). Then use imwrite(). Let me know if you can't figure it out.

You should click on the "Show older comments" link. Then you'd see
props = regionprops(mask, 'BoundingBox');
croppedImage = imcrop(rgbImage, props.BoundingBox);
save(croppedImage, filename);
If you need more help with your image, post a new question after reading this:

I have no idea what you're asking. Please try to rephrase, and attach some screenshots, in a new question (not back here). Basically I think you want to use ind2rgb() and somehow want to change the colormap with each image, though I'm not sure how you're going to decide how to change the colormap each time.
