Handling corrupt images #1467

Open saketsneha opened 4 years ago

saketsneha commented 4 years ago

I am using val sourceImageMat = imread(sourceImage.toString()) to read a file in java. But for corrputed images it just prints Premature end of JPEG file . I can see its not an exception and that is why its not ignoring the image but processing it further. Is there a way to avoid this processing? Have had a look at the community channel but was not of much help.Hope you can throw some ideas around this?

In that case, sourceImageMat.empty() will be true, so you can throw an exception on that if you need it.

@saudet no its not returning empty Mat

saketsneha commented 4 years ago

@saudet I have this condition added if (!sourceImageMat.empty()) {} , its still going inside

You can try to use Leptonica instead. It has more options when it comes to loading images.

its a completely different library , there is nothing in javacv that can be helpful?I am not wanting to a new library.Thanks for reopening.

Leptonica is part of JavaCV...
