做深度学习,有大量图片需要做为训练集,为方便批量resize,rename,灰度化,制作python脚本。先纪录一些函数:resizedef resizeimage(readpath,savepath,width,height): try: '''调用cv2.imread读入图片,读入格式为IMREAD_COLOR''' '''使用os.path模块的join方法生成路径''' img_array = cv2.imread(os.path.join(...
You've reached a point where Python's type system is not offering the same level of protection as C++. The valuescv2.IMREAD_GRAYSCALEandcv2.COLOR_BGR2GRAYbelong to distinct enumerations.cv2.IMREAD_GRAYSCALE, which has a numerical value of 0, pertains tocv2.imread(), whilecv2.COLOR_BGR2...
