Modules
Overview
FEZrs embraces the "simple yet powerful" design principle.
Most tools in this library share a unified structure and can be used in a similar way — this makes learning and using FEZrs extremely easy and intuitive.
These modules serve as core calculators for the main tool categories like:
change_detectionclusteringfiltersglcmhsvimage_enhancementimport_toolsmosaicpcaspectral_indicesspectral_profilesvm
Each module is accessible directly and can be plugged into custom workflows or pipelines built on BaseTool.
