CascadeClassifier fails in x64?

[kobush]

I have run into same issue. My app works on x86 but it fails with System.AccessViolationException in x64. It occurs in call to objdetect_CascadeClassifier_detectMultiScale2 native method.

Thank you. The error also occurred in my environment.
But the definition of the detectMultiScale wrapper seems to be correct...

I've looked a bit more into this. Hitting a breakpoint in objdetect_CascadeClassifier_detectMultiScale1 I could see that in x64 build the arguments are not passed correctly. In particular the pointers are all wrong (but scale factor too). Compare with x86 version below.

And I tried to call CascadeClassifier Load method now and it gives the same error. In debug I can see the obj pointer and fileName string are passed wrong.

I released the new version now. Probably this problem is resolved. please retry with the new dlls.

I realized that argument value of C++ class causes error in x64 (e.g. cv::Size). I replaced cv::Size with the simple struct CvSize.　FYI, pointer of C++ class argument (e.g. cv::Point* ) seems to be OK.

I installed 20140510 x64 nuget.
result : fine. thank you.
