Python array_to_polygons Examples

Example #1

File: rasterizer.py Project: pereirapysensing/pyfor

 def __init__(self, array, grid, min_distance, threshold_abs):
     from skimage.morphology import watershed
     super().__init__(array, grid)
     watershed_array = np.flipud(self.array)
     tops = self.local_maxima(min_distance=min_distance, threshold_abs=threshold_abs).array
     labels = watershed(-watershed_array, tops, mask=watershed_array)
     self.segments = gisexport.array_to_polygons(labels, affine=None)

Example #2

File: rasterizer.py Project: ns-1m/pyfor

 def segments(self):
     return gisexport.array_to_polygons(self.labels, affine=self._affine)
