DespeckleImage

DespeckleImage() reduces the speckle noise in an image while perserving the edges of the original image.

DespeckleImage() reduces the speckle noise in an image while perserving the edges of the original image. A speckle removing filter uses a complementary hulling technique (raising pixels that are darker than their surrounding neighbors, then complementarily lowering pixels that are brighter than their surrounding neighbors) to reduce the speckle index of that image (reference Crimmins speckle removal).

The format of the StatisticImage method is:

channel
-

the image channel.

- -
type
-

the statistic type (median, mode, etc.).
