opencv读取图像"JPEG文件的过早结尾" [英] opencv read image “Premature end of JPEG file”

问题描述

我正在使用OpenCV从文件夹中读取图像.出现很多这样的消息:

I was using OpenCV to read the images from a folder. A lot of messages like this show up:

Corrupt JPEG data: premature end of data segment
Premature end of JPEG file
Premature end of JPEG file
Premature end of JPEG file

如何捕获此异常并删除这些图像文件?

How to catch this exception and remove these image files?

推荐答案

由于您说您正在读取图像"(多张图像)，因此您将在要从中读取文件的文件夹中循环浏览文件. 在这种情况下，如果使用以下方法检查图像是否有效:

Since you said you are reading 'images' (multiple images), you would be looping through files in the folder that you are reading them from. In that case, if you check if the image is valid or not by using the following :

Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR);   // Read the file

if(! image.data )                              // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}

然后您可以继续删除损坏/损坏的文件.

you can then proceed to deleting files which are corrupt/bad.
