在Python中以编程方式裁剪图像/删除背景

from PIL import Image
import numpy as np
import matplotlib.pyplot as plt

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

image_array = np.array(image)

# 将图像转换为灰度图像
gray_image = image.convert('L')

# 对灰度图像进行阈值分割
threshold = 128
binary_image = gray_image.point(lambda x: 0 if x < threshold else 255, '1')

# 显示处理后的图像
plt.imshow(binary_image, cmap='gray')
plt.axis('off')
plt.show()

binary_image.save('processed_image.jpg')
