MaskSharpPlugin
Sharpening plugin for segmentation mask
Applies a smart sharpening filter on a segmentation mask. This plugin may significantly increase accuracy of a mask. Plugin depends on MaskUploadPlugin that must be attached to the renderer to upload mask buffer in texture. It may be combined with other mask post-processing plugins. Order in which operation on mask are applied corresponds to the order in which plugins are attached to the renderer.
