Description

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?

Contributor guide

Research direction
Investigate how imread handles corrupt images and where the error message 'Premature end of JPEG file' is produced. Look at OpenCV source code for imread and JPEG decoder to see if there is a way to detect corrupt images without processing them further. Consider using error flags or try catch blocks.
