思路很简单,就是读取图片,获取高宽,创造一个图片的模板,然后依次将三个通道的像素加权融合一下,再保存。
import cv2
import numpy as np
import osroot = "./test"
for file in os.listdir(root):print(file)image = cv2.imread(os.path.join(root,file))#读取图片像素高宽 sp = image.shape height = sp[0] width = sp[1] #创建同样高宽的画布 new = np.zeros((height,width), np.uint8) #遍历每个像素 #使用加权平均法算得灰度图 for i in range(height): for j in range(width): new[i,j] = 0.1 * image[i,j][0] + 0.1 * image[i,j][1] + 0.1 * image[i,j][2] cv2.namedWindow('Image') cv2.imshow('Image', new) new_path = "./test/"+ file.split(".")[0] + "_grey.png"cv2.imwrite(new_path, new) cv2.waitKey(0) cv2.destroyAllWindows()
