FilterAdaptiveMMSE  Method

Description         This function will filter the image by the adaptive MMSE filter method. This function works for only monochrome, 8 bit per pixel and 24 bit per pixel images. The minimum mean-square error filter makes use of the knowledge of the local variance to determine if a mean filter is to be applied to the local region of an image. This filter works best for additive type short tail noise.
