What are the methods for iterating over pixel points in Python?

In Python, you can traverse pixels using the following method:

1. Visual representation
2. carry a heavy burden

from PIL import Image

# 打开图像文件
image = Image.open('image.jpg')

# 加载图像的像素数据
pixels = image.load()

# 遍历每个像素点
for i in range(image.width):
    for j in range(image.height):
        # 获取像素点的RGB值
        r, g, b = pixels[i, j]
        # 处理像素点的操作

1. Resume
2. reading an image with OpenCV

import cv2

# 读取图像文件
image = cv2.imread('image.jpg')

# 遍历每个像素点
for i in range(image.shape[0]):
    for j in range(image.shape[1]):
        # 获取像素点的BGR值
        b, g, r = image[i, j]
        # 处理像素点的操作

1. array

import numpy as np

# 读取图像文件
image = np.array(Image.open('image.jpg'))

# 遍历每个像素点
for i in range(image.shape[0]):
    for j in range(image.shape[1]):
        # 获取像素点的RGB值
        r, g, b = image[i, j]
        # 处理像素点的操作

These methods can all be used to iterate through the pixels of an image, the choice of which method to use depends on specific needs and personal preferences.
