如何RGB混合剪切强度和显示正确的混合强度与imshow？

import cv2

def blend_images(image1, image2, blend_strength):
    # 调整图像大小为相同尺寸
    image1 = cv2.resize(image1, (image2.shape[1], image2.shape[0]))
    
    # 创建空白图像
    blended_image = np.zeros_like(image1)
    
    # 遍历每个像素并进行混合
    for i in range(image1.shape[0]):
        for j in range(image1.shape[1]):
            blended_image[i, j] = blend_strength * image1[i, j] + (1 - blend_strength) * image2[i, j]
    
    return blended_image

# 加载两个RGB图像
image1 = cv2.imread('image1.jpg')
image2 = cv2.imread('image2.jpg')

# 设置剪切强度
blend_strength = 0.5

# 进行RGB混合剪切强度
blended_image = blend_images(image1, image2, blend_strength)

# 显示混合后的图像
cv2.imshow('Blended Image', blended_image)
cv2.waitKey(0)
cv2.destroyAllWindows()
