在OpenCV中使用imread()加载图像时，如何捕获损坏的JPEG? [英] How can I catch corrupt JPEGs when loading an image with imread() in OpenCV?

问题描述

OpenCV说类似

Corrupt JPEG data: premature end of data segment

或

Corrupt JPEG data: bad Huffman code

或

Corrupt JPEG data: 22 extraneous bytes before marker 0xd9

当使用imread()加载损坏的jpeg图像时. 我能以某种方式抓住它吗?否则我为什么会得到这些信息? 我必须自己检查二进制文件吗?

when loading a corrupt jpeg image with imread(). Can I somehow catch that? Why would I get this information otherwise? Do I have to check the binary file on my own?

推荐答案

如果使用imread()，则无法捕获它.但是，有imdecode()函数由imread()调用. 也许，它可以为您提供更多反馈.为此，您必须自己将图像加载到内存中，然后调用解码器.

You cannot catch it if you use imread(). However there is imdecode() function that is called by imread(). Maybe it gives you more feedback. For this you would have to load the image into memory on your own and then call the decoder.

它可以归结为:您必须深入研究OpenCV来源才能解决您的问题.

It boils down to: You have to dig through the OpenCV sources to solve your problem.
