使用Python将两个图像叠加在一起

from PIL import Image

def overlay_images(image1_path, image2_path, opacity):
    # 打开两个图像文件
    image1 = Image.open(image1_path)
    image2 = Image.open(image2_path)

    # 调整第二张图像的大小为第一张图像的大小
    image2 = image2.resize(image1.size)

    # 对两张图像进行叠加
    blended_image = Image.blend(image1, image2, opacity)

    # 显示并保存叠加后的图像
    blended_image.show()
    blended_image.save('overlay_image.jpg')

# 示例使用
image1_path = 'image1.jpg'
image2_path = 'image2.jpg'
opacity = 0.5
overlay_images(image1_path, image2_path, opacity)

import cv2

def overlay_images(image1_path, image2_path, output_path):
    # 读取两个图像文件
    image1 = cv2.imread(image1_path)
    image2 = cv2.imread(image2_path)

    # 调整第二张图像的大小为第一张图像的大小
    image2 = cv2.resize(image2, (image1.shape[1], image1.shape[0]))

    # 设置图像叠加的透明度
    opacity = 0.5

    # 将两张图像进行叠加
    overlay = cv2.addWeighted(image1, 1-opacity, image2, opacity, 0)

    # 显示并保存叠加后的图像
    cv2.imshow('Overlay Image', overlay)
    cv2.imwrite(output_path, overlay)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

# 示例使用
image1_path = 'image1.jpg'
image2_path = 'image2.jpg'
output_path = 'overlay_image.jpg'
overlay_images(image1_path, image2_path, output_path)
