How to perform binary dilation on a grayscale image?

I would like to write a function that performs binary dilation on a grayscale image.

I would like to be able to change the kernel that is moved across the image.

I plan on padding the image in order to perform this binary dilation.

Try imdilate():

kernel = strel('disk', 15, 0); % Or whatever you want.
filteredImage = imdilate(binaryImage, strel);
