ArcGIS Toolbox/ArcPy Script
The inputs for this tool are an NDVI change detection map, DEM and post-event RGB image. The tool uses the inputs to remove flat areas and areas of no-change from the post-event image. The clipped image is then segmented for use in the desired classifier. The final image will be named 'SEGMENTED_CLIPPED_IMAGE.tif' and saved in the workspace defined.
This toolbox can be used to threshold and segment RGB images for the purpose of landslide detection. This thresholding method removes flat areas and area of no-change in the imagery so as to reduce the amount of false-positives when classifying the imagery for landslide detection purposes. An example is shown below.
