fill the image from the boundary of the mask

Hi all

I need to do inpainting for a image in matlab. Opencv is having the function for image inpainting where the mask region is created for the zero pixel of the input image,the mask region is filled from its outer boundary to inner side. So my process would be iterative for filling the image from outside boundary of mask region to the inner side. I need to fill the region with the maximum value of the neighbourhood for the boundaries of the mask. After filling the region the filled region should contribute to the next maximum calculation.

I have tried using dilate operation on the mask and subtract that from the mask to find the boundary of the image. Used that to fill that region from the neighbourhood max values.

I have attached the input file here. I tried to do dilation and fill the region.

Try bwboundaries followed by regionfill
