python中具有窗口大小计算的缩放共生矩阵

from PIL import Image
import numpy as np

image = Image.open('image.jpg').convert('L')

scale = 0.5
window_size = 5

scaled_image = image.resize((int(image.width*scale), int(image.height*scale)))

image_array = np.array(scaled_image)

co_occurrence_matrix = np.zeros((256, 256))
for i in range(window_size, image_array.shape[0]-window_size):
    for j in range(window_size, image_array.shape[1]-window_size):
        window = image_array[i-window_size:i+window_size+1, j-window_size:j+window_size+1]
        co_occurrence_matrix[window[window_size, window_size], window[window_size, window_size+1]] += 1

co_occurrence_matrix /= np.sum(co_occurrence_matrix)

print(co_occurrence_matrix)
