I want to replace the zero valued pixels inside the object with the average of their non-zeros neighbours. whats the best way doing that?

That's similar to what I do with my salt and pepper denoising program (attached) - I replace with the median.
To get the average, you'd use conv2() instead of medfilt2(). You'd have to replace the zero pixels with nan's and then see if conv2() will work if there are nan's in the image. If so, do
grayImage(grayImage == 0) = nan;
blurredImage = conv2(grayImage, ones(5)/25, 'same');
% Replace nan's with average
badPixels = isnan(grayImage);
grayImage(badPixels) = blurredImage(badPixels);
