How can I catch corrupt JPEGs when loading an image with imread() in OpenCV?

OpenCV says something like

Corrupt JPEG data: premature end of data segment

or 

Corrupt JPEG data: bad Huffman code

or

Corrupt JPEG data: 22 extraneous bytes before marker 0xd9

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?

Solution

  • 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.

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