Remarks
|
raster |
an input Raster, RasterDataset, RasterBand, or RasterDescriptor |
|
useDiagonalNeighbors |
a Boolean specifying the number of cells in the filter kernel If True, then the kernel of the filter will be the eight nearest neighbors (a 3-by-3 window) to the present cell. If False, then the kernel of the filter will be the four direct (orthogonal) neighbors to the present cell. This is the default. |
|
halfIsMajority |
a Boolean specifying the number of contiguous (spatially connected) cells that must be of the same value before a replacement will occur If True, half of the cells must have the same value and be contiguous. Two out of four or four out of eight connected cells must have the same value. Half will have more of a smoothing effect. If False, a majority of cells must have the same value and be contiguous. Three out of four or five out of eight connected cells must have the same value. This is the default. |
