通道交换：import cv2# function: BGR -> RGBdef BGR2RGB(img): b = img[:,:,0].copy() g = img[:,:,1].copy() r = img[:,:,2].copy() #RGB > BGR img[:,:,0] = r img[:,:,1] = g img[:,:,2] = b return imgimg = cv2.imread('full.jp.

11.均值滤波：import cv2import numpy as np#Mean filterdef mean_filter(img,K_size=3): if len(img.shape) == 3: H,W,C = img.shape else: H,W,C = np.expand_dims(img,axis=-1) H,W,C = img.shape #zero padding pad = K_size//2
