I am working on a blur detection with OpenCV for Android and used following code found here on Stackoverflow which seemed to work correctly:
https://stackoverflow.com/a/37245961/1804084
Now, my problem is that it crashs, if the resolution of the image is too small. In the sample code the transformed image gets resized to 2000*2000, but only if it is bigger than that.
It happens here:
Imgproc.Laplacian(matImageGrey, laplacianImage, CvType.CV_8U);
I have tested it serveral times and no crash with big images!
No crash image resolution: 1048 * 1048
Crash with resolution: 511*511
Does anybody now why this happens? It seems that there is a minimum image resolution size needed, but I can not find any info in the OpenCV documentation or in the internet.
Thanks!
