This can be done in one line of code with imreconstruct().
J = imreconstruct(marker,mask) performs morphological reconstruction of the image marker under the image mask, and returns the reconstruction in J. The elements of marker must be less than or equal to the corresponding elements of mask. If the values in marker are greater than corresponding elements inmask, then imreconstruct clips the values to the mask level before starting the procedure
