python - 使用python库在图像中填充穿孔的形状？

我有带有“穿孔”的BW图像。穿孔水平可以不同



是否有任何“标准”方法可以完全用黑色填充形状以使其更相似？

首选枕头和opencv，但imagemagick也可以。

最佳答案

您可以使用image morphology(i.e: closing)来实现。

import cv2
import numpy as np

if __name__ == '__main__':
    # read image
    image = cv2.imread('image.png',cv2.IMREAD_UNCHANGED)

    # convert image to gray
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

    # ensure only black and white pixels exist
    ret,binary = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY)

    # morphology works with white forground
    binary = cv2.bitwise_not(binary)

    # get kernel for morphology
    kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (3,3))
    # number of iterations depends on the type of image you're providing
    binary = cv2.morphologyEx(binary, cv2.MORPH_CLOSE, kernel, iterations=3)

    # get black foreground
    binary = cv2.bitwise_not(binary)

    cv2.imshow('image', binary)
    cv2.waitKey(0)
    cv2.destroyAllWindows()
