From time to time I get this exception:

"X:\Dev\git\opencv-2.4\modules\imgproc\src\shapedescr.cpp:799: error: (-201) Number of points should be >= 5 in function CvBox2D cvFitEllipse2(const CvArr*)"

This happens when running opencv on android 4.0.4. We use the latest opencv manager with up to date 2.4.2 neon module.

Any ideas howto avoid this?

You exception has nothing to do with CascadeClassifier.

you are right. I could not exactly track down the source of the exception in the native code. But your answer helped a lot! Thanks.
