Can you tell me please where i can find “cv200d.lib” , “cxcore200d.lib” , “highgui200d.lib” , “ml200d.lib” modified to be used on mobile with their dlls ?? (I want these files instead of “cv200.lib” , “cxcore200.lib” , “highgui200.lib” , “ml200.lib” that i work with now because I think that the first files will help me in detecting faces on windows mobile )

Waiting for your answer

Yours ,
John

I suspect in two things :
1- May be the mobile application can’t support all the data and the floating points in the haarcascade so it crashes but when i tried to search a haarcascade for mobiles i didn’t find anything
2- I tried putting data manually in the haarcascade variable by writing
cascade-> count = 3 without loading any haarcascade and it crashes but when making cascade no pointer but a normal object and writing : cascade.count = 3
it accepted and completed debugging but i faced problems after that in the line of CVSeq* faces because it’s a pointer too and i don’t know how to fix it

I am not sure if it’s a pointer problem or haarcascade problem .

Waiting for your reply and sry for my weak english .

Yours, John

Is there any extended error description available? What exactly “stops” means? Is there any exception?

thx for that nice blog

My problem is : my software stops at “cascade = (CvHaarClassifierCascade*)cvLoad( “haarcascade_frontalface_alt2.xml”, 0, 0, 0 );” although i wrote the right path to the xml existing on the mobile emulator . What can be the problem ? waiting for your answers .

Thx again

John

Read more about that here. http://social.msdn.microsoft.com/Forums/en-US/windowsmobiledev/thread/6e535905-6544-4c89-9b18-94d4b440d6c1

I can run opencv in my wince system.but I do not run “cascade = (CvHaarClassifierCascade*)cvLoad( “haarcascade_frontalface_alt2.xml”, 0, 0, 0 );”.Can you tell me How do you run “cvLoad” to get “cascade”?

All information starting from preprocessor definitions is about project settings in visual studio. This is required because by default all settings are for win32 configuration.

libjpeg was not compiled for wince platform, so only bmp can be loaded via cvLoadImage. Instead standard wince com objects can be used to read jpeg data and pass it into cvCreateImage.

Here is code sample that reads jpeg from file, creates IplImage in rgb565 format and converts it to grayscale.

….

IImagingFactory *pImgFactory = NULL;
CHK( CoCreateInstance (CLSID_ImagingFactory, NULL,
CLSCTX_INPROC_SERVER,
IID_IImagingFactory,
(void **)&pImgFactory));

IplImage* rgb565_image = NULL;
IplImage* grayImage = NULL;
IImage *pImageJpeg = NULL;
IBitmapImage *pImageBitmap = NULL;

BitmapData newData;
ZeroMemory(&newData, sizeof(newData));

CHK(pImgFactory->CreateImageFromFile( L”\\My Documents\\barcode.jpg”, &pImageJpeg) );

ImageInfo* imageInfo = new ImageInfo();
CHK( pImageJpeg->GetImageInfo(imageInfo) );

CHK ( pImgFactory->CreateBitmapFromImage( pImageJpeg,
0,
0,
PixelFormat16bppRGB565,
InterpolationHintDefault,
&pImageBitmap) );

// Lock the bitmap’s bits.
RECT rect;
rect.top = 0;
rect.bottom = imageInfo->Width;
rect.left = 0;
rect.right = imageInfo->Height;

CHK (pImageBitmap->LockBits( &rect, ImageLockModeRead, PixelFormat16bppRGB565, &newData ));

// Create color image
rgb565_image = cvCreateImage( cvSize(newData.Width, newData.Height), IPL_DEPTH_8U, 2);
cvInitImageHeader( rgb565_image, cvSize(newData.Width, newData.Height), IPL_DEPTH_8U, 2, IPL_ORIGIN_BL, 4 );
cvSetData( rgb565_image, newData.Scan0, newData.Stride );

// Create gray image
grayImage = cvCreateImage(cvGetSize(rgb565_image),IPL_DEPTH_8U, 1 );
cvCvtColor(rgb565_image, grayImage, CV_BGR5652GRAY);

pImageBitmap->UnlockBits( &newData );

….

For a complete description of image manipulation under wince, I suggest the msdn articles about “IImagingFactory”, “IImage” and “IBitmapImage” classes.

Changed preprocessor definitions to NDEBUG;_WIN32_WCE=$(CEVER);UNDER_CE;$(PLATFORMDEFINES);WINCE;_WINDOWS;_USRDLL;CV_CE_EXPORTS;$(ARCHFAM);$(_ARCHFAM_);_

would mind explain that means. Thank you.
