To many patches after tiling (for flood modelling interest)

[Abdielfer]

After tiling, the destination folder contains all possible patches from the raster image, event when there is not ground truth (GT) labels matching (< min_annot_perc). Flood happens close to water bodies, and in general, flood extensions represents a small percent of surface from the original images. Therefore, majority of patch have no GT match. Should a cleaning process be implemented into DGL (automatically or not) or as an independent script?
