Image conversion to RGB

How to convert the binary image (which is extracted from regionprops command) to again RGB image

here is the sample command

stats = regionprops(L,'Area','Centroid', 'Image');

stats is not a image....it is a structure with your required information.

With difficulty. You would have to do something like xcorr2 in order to locate stats(K).Image within the label image.

It is a lot easier to instead request PixelIdxList or PixelList or SubarrayIdx, which give you information about the locations within the label image, and use those indices to extract the RGB from the original image. Or perhaps easier would be to use Image together with BoundingBox:

stats = regionprops(L, 'Area', 'Centroid', 'Image', 'BoundingBox');
for K = 1 : length(stats)
    BB = stats(K).BoundingBox;
    blobRGB = imcrop(YourRGBImage, BB);
    mask = repmat(stats(K).Image, [1 1 3]);
    blobsRGB{K} = blobRGB .* mask;
end

I got this error when using the above code

Error using .*

Integers can only be combined with integers of the same class, or scalar doubles.

Error in tablets (line 149)

blobsRGB{K} = blobRGB .* mask;

[Walter Roberson]

blobsRGB{K} = blobRGB .* cast(mask, class(blobRGB));

Thanks :)

x = stats(k).Image

x is the segemented binary image given from the regionprops function

k is the index of array

Here is the image of x
