WitrynaFilter Multidimensional Truecolor (RGB) Image Using imfilter. Read a truecolor image into the workspace. rgb = imread ( "peppers.png" ); imshow (rgb); Create a filter. This averaging filter contains equal weights, and causes the filtered image to look more blurry than the original. h = ones (5,5)/25; Filter the image using imfilter and display it.

When we say that we are using a kernel size of 3 or (3,3), the actual shape of the kernel is 3-d and not 2d. A kernel's depth matches the number of channels in the input to the convolutional layer. For example,
