I want to create a new dataset same as coco format, and now I have converted mask binary image to RLE format by using encode function in mask.py. But I don't know how to convert mask binary image or RLE format to polygon format, someone ...
Can not make binary mask from self-intersected polygon. import numpy as np from PIL import Image, ImageDraw def show(img,full=False): if full: display(Image.fromarray(np.uint8(img))) else: img = resize(img,300) display(img) def polygons_to_mask(poly,shape): def points_...
I would like to extract this polygon as a binary mask (ideally a numpy array). How would I go about doing this? I have also managed to convert from shapely to geopandas as shown here so extracting a mask from geopandas would work as well, but I have not really been able to find a...
