These are Maximum Homogeneity Neighbor Filters. The standard from Nagao: At each point the variance of 9 masks are compared with each other, and the average gray level of the least variance mask is given to the point. There is one traditional 3 by 3 mask, an up 7 point pentagonal mask, a down 7 point pentagonal mask, a left 7 point pentagonal mask, a right 7 point pentagonal mask, and 4 diagonal 7 point hexagonal masks. Extended From Wang: The 9 masks used all have 9 points. 5 are traditional 3 by 3 masks. 4 are 5,3,1 stacks.
