python通过opencv实现批量剪切图片

import cv2import osdef cutimage(dir,suffix): for root,dirs,files in os.walk(dir):  for file in files:   filepath = os.path.join(root, file)   filesuffix = os.path.splitext(filepath)[1][1:]   if filesuffix in suffix:  #遍历找到指定后缀的文件名["jpg",png]等    image = cv2.imread(file) #opencv剪切图片      #cv2.imshow(file,image)     dim =(242,200)      #指定尺寸w*h    resized =cv2.resize(image,dim,interpolation = cv2.INTER_AREA) #这里采用的插值法是INTER_LINEAR    #cv2.imshow("resize:%s"%file,resized)    cv2.imwrite("../cv/%s"%file,resized) #保存文件  cv2.waitKey(0)     #退出suffix = ["jpg"]dir = '.'cutimage(dir,suffix)
