Hello GDAL Dev team, As far as I know gdal_sieve is the only GDAL raster generalization tool and one of the few open source ones in general.
I would suggest to create a tool (or a few of them) that could use generalization alghoritms like expansion (dilation), shrinking (erosion), boundary smoothing, majority filtering, group segmentation and similar for classified raster images. I have been using GDAL and developing GIS tools for a few years, and have been a GIS user for a few more, but I am not familiar with what the procedure is for building/suggesting new functionalities to the GDAL project. Kind regards, Mihovil
