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_...
def binary_mask(tile_poly: Polygon, wkt_mp: MultiPolygon) -> npt.NDArray[np.int_]: min_x, min_y, max_x, max_y = tuple(map(int, tile_poly.bounds)) mask = np.zeros((max_x - min_x, max_y - min_y)) for x in range(min_x, max_x): for y in range(min_y, max_y): ...
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 ...
Here's an example finding the coordinates then drawing the polygon onto a blank mask import cv2 import numpy as np image = cv2.imread('1.png', 0) x,y,w,h = cv2.boundingRect(image) mask = np.ones(image.shape, dtype=np.uint8) * 255 mask = cv2.merge([mask,mask,mask]) cv2.recta...
I have seen this question asked but have not really been able to find a full response. I have a simple shapely polygon, called polygon. 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 fro...
