Speckle Remover

Speckle Remover

The Speckle Remover filter removes raster objects (isolated pixel groups) that are smaller than those of the specified value. This filter can automatically estimate the speckle size in the image.
The filter can be used after such procedures as binarization and layering to remove low-sized raster objects in the obtained monochrome images’ layers.
