Description

When opencv_traincascade is training Haar features and precalcValBufSize or precalcIdxBufSize is 2048 Mb or greater, opencv_traincascade crashes with the following exception:

OpenCV Error: Unsupported format or combination of formats (Invalid matrix type) in cvCreateMatHeader, file /home/cheparukhin/Downloads/OpenCV-2.4.3/modules/core/src/array.cpp, line 117
terminate called after throwing an instance of 'cv::Exception'
what(): /home/cheparukhin/Downloads/OpenCV-2.4.3/modules/core/src/array.cpp:117: error: (-210) Invalid matrix type in function cvCreateMatHeader

Such problem doesn't seem to appear with LBP features.

Alexander, is it possible to get your vec file and parameters for the training utility?

You can try to create a synthetic vec-file, so we can reproduce the error. Otherwise the fixing process might be extremely slow... And, if you'll be able to resolve the issue, please don't mind to send a pull request!

I think compile the opencv_traincascade with 64bit opencv will fix this problem. You can alloc more memory during opencv_traincascade training with 64bit opencv.

I believe, now the bug is solved in 3.0-pre, but big buffers (>2Gb) are only supported on 64-bit machines

Yep it works just fine here!
