C# Класс Accord.Imaging.Filters.Mean

The filter performs each pixel value's averaging with its 8 neighbors, which is convolution filter using the mean kernel:

For the list of supported pixel formats, see the documentation to Convolution filter.

With the above kernel the convolution filter is just calculates each pixel's value in result image as average of 9 corresponding pixels in the source image.

By default this filter sets Convolution.ProcessAlpha property to , so the alpha channel of 32 bpp and 64 bpp images is blurred as well.

Sample usage:

Initial image:

Result image:
