使用python和numpy递归填充图像

import numpy as np

def recursive_fill(image, start_pixel, fill_color):
    height, width = image.shape[:2]
    target_color = image[start_pixel[0], start_pixel[1]]

    def fill(pixel):
        x, y = pixel
        if x < 0 or x >= height or y < 0 or y >= width:
            return
        if image[x, y] != target_color or image[x, y] == fill_color:
            return
        image[x, y] = fill_color
        fill((x-1, y))
        fill((x+1, y))
        fill((x, y-1))
        fill((x, y+1))

    fill(start_pixel)

# 示例用法
image = np.array([[1, 1, 1, 1, 1],
                  [1, 0, 0, 0, 1],
                  [1, 0, 1, 0, 1],
                  [1, 0, 0, 0, 1],
                  [1, 1, 1, 1, 1]])

start_pixel = (2, 2)
fill_color = 2

recursive_fill(image, start_pixel, fill_color)
print(image)
