塔伯自我指涉由图片生成K值python程序

import matplotlib.image as mpimg
import numpy as np


def rgb2gray(rgb):
    return np.dot(rgb[..., :3], [0.2989, 0.5870, 0.1140])


img = mpimg.imread("in.png")  # 输入文件名

H = img.shape[0]
W = img.shape[1]
print(f"H = {H}, W = {W}")
img = rgb2gray(img)
threshold = 0.5  # 阈值，0表示纯黑，1表示纯白，用于黑白化图片
K = 0
for x in reversed(range(W)):
    for y in range(H):
        K = (K << 1) + int(img[y, x] < threshold)
K *= H
print(K)

样例

输入图片in.png：

输出结果：

H = 17, W = 106
