MATLAB: How to retrieval back the color in particular area from original image

colorImage Processing Toolboxmask

13100.jpg
colorImage = imread('13100.jpg');
grayImage = rgb2gray(colorImage);
mserRegions = detectMSERFeatures(grayImage);
mserRegionsPixels = vertcat(cell2mat(mserRegions.PixelList));
mserMask = false(size(grayImage));
ind = sub2ind(size(mserMask), mserRegionsPixels(:,2), mserRegionsPixels(:,1));
mserMask(ind) = true;
figure;imshow(mserMask);
MSER mask
How to retrieve back the original color from 13100.jpg and paste into MSER mask (white area)?

Best Answer

Much simpler:
maskedimage = immultiply(colorImage, repmat(mserMask, [1, 1, size(colorImage, 3)]));
imshow(maskedimage);
Note that if you just want to see if your mask is correct
imshowpair(colorImage, mserMask, 'blend');
 may be more useful.
