Note that I didn't flipped filter here since the filter is symmetric in both directions. And I recommend you to avoid loops! There are nested loops of depth four in your code! Lastly, you can use 2-D convolution to do the same as imfilter:

Witryna26 paź 2011 · Sorted by: 9. conv2 outputs the entire 2-D convolution, which means that yconv2 will be bigger than mypic. imfilter, on the other hand, by default trims the edges of the convolution so that yimfilter should be the same size as mypic. You can make imfilter leave the entire convolution like conv2 does, but that is not its default behavior.

The outermost input image matrix rows and columns are extended to the borders, replacing the zeros. I am doing this to emulate the 'replicate' option in 'imfilter'. Use 'fft2' to convert both the input image and kernel to frequency domain. Element wise multiply the two together

WitrynaTo eliminate the zero-padding artifacts around the edge of the image, imfilter offers an alternative boundary padding method called border replication. In border replication, the value of any pixel outside the image is determined by replicating the value from the nearest border pixel.
