GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.I want to process the pic by android camera dynamically,such as cvCvtColor or 
cvCanny
2.I can get the data(onPreviewFrame) to IplImage .But after process,i get the 
result is Bitmap by ImageView display(so bother),and the frame rate is low.It 
look likes so slow.Actually I know it isnot a proper method. 
3.I want to know how to process data(onPreviewFrame) directly by JavaCV then 
the result also display in SurfaceView.

cvCanny() is a heavy operation. It's perfectly normal for it to be "slow".

Please ask your questions on the mailing list next time if possible, thank you.
