2013-12-14 12:28:48 -0500 asked a question opencv_traincascade.exe is not a valid Win32 application

Hi, I tried to train a cascade classifier, but I got an error, when I want to start opencv_traincascade application:

Other utilities (i. e. createsamples) work fine. Some days ago traincascade didn't cause any problems too.

I use Winows 7, thanks i advance.

Hi, I'm trying to train simple cascade classifier. I've created vec file with createsamples utility. But when i try to train classifier with command:

C:\ocv_sample> ..\opencv\build\x64\vc10\bin\opencv_traincascade.exe -data data -vec positive\myvec.vec -bg negative\bg.txt -numPos 3 -numNeg 5 -numStages 2 -w 300 -h 50 -featureType LBP
I get an error:

Cascade classifier can't be trained. Check the used training parameters.
My directory structure looks like:

bg.txt:

I use Win7. What am i doing wrong?

Could you show how your Android.mk file looks like now? I have this same problem and still can't solve it.

Hi, Hi, first of all sorry for my bad English. I'm new to OpenCV and have tried to run android samples, but I have problem with samples with native code. When I try to run face-detection I get an error: image description

Console output looks like:

20:50:33 * Auto Build of configuration Default for project OpenCV Sample - face-detection * "C:\adt-bundle-windows-x86_64-20130219\android-ndk-r9\ndk-build.cmd" Android NDK: WARNING:jni/Android.mk:detection_based_tracker: non-system libraries in linker flags: -lopencv_java

Any ideas how can I solve it? Thanks in advance.
