r.mapcalc | Raster map calculator.
r.mfilter | Performs raster map matrix filter.
r.mode | Finds the mode of values in a cover map within areas assigned the same category value in a user-specified base map.
r.neighbors | Makes each cell category value a function of the category values assigned to the cells around it, and stores new cell values in an output raster map layer.

r.texture | Generate images with textural features from a raster map.
r3.mapcalc | Raster map calculator.
r3.neighbors | Makes each voxel value a function of the values assigned to the voxels around it, and stores new voxel values in an output 3D raster map
t.rast.mapcalc | Performs spatio-temporal mapcalc expressions on temporally sampled maps of space time raster datasets.
t.rast3d.mapcalc | Performs r3.mapcalc expressions on maps of sampled space time 3D raster datasets.
