imdilate algorithm similar to convolution?

what is the algorithm used in imdilate function....is it similar to convolution...is it like structuring element is flipped and translated over the given set and convolution is taken?/

                                      please reply soon....thanks......

No, it's totally different. They both scan the image with a window but the convolution multiplies the values in the window by the image values under the window and sums them up to get a new center pixel. The dilate just takes the maximum value in the window as the new center pixel.

Dilation is scanning the input image with a window and replacing the center location of the output image with the max of the input image inside the window.
