以前用的是这套接口，总感觉慢腾腾的，像老大爷散步def bin2numpy(file_path, shape): pic_gray = np.zeros(shape) with open(file_path, "rb") as f: for i in range(shape[0]): for j in range(shape[1]): data = f.read(2) pix = str

经常遇到需要将处理后的三个图像数据通道进行合并，记录一下import numpy as npimport cv2'''这里需要改一下默认通道顺序,cv2默认的是bgr顺序'''img = cv2.imread('./xx.jpeg')[:, :, [2, 1, 0]]Red = img[:, :, 0] * 0.3Green = img[:, :, 1] * 0.6Blue = img[:, :, 2] * 0.1new_img...
