Hi @SIME-LAB , just in case it helps, here is what I implemented to create mask polygons: import numpy as np import cv2 from shapely.geometry import Polygon def mask_to_polygons(img_path, mask_path): ''' Convierte una máscara de imagen en polígonos. Devuelve dos listas: - Lista ...

Since you don't want to rasterize your polygons, the other options is to make polygons from the raster mask. Here is an example using rasterio.features.shapes from the python rasterio package and with the following image and polygons. I used the all white cloud pixels as ...
