Issue with javacv implementation of HOG descriptor about javacv HOT 10 CLOSED

Strange, I wonder why they use different types in C++ if they are supposed to 
be the same type. I will be providing a setSVMDetector(FloatPointer) method in 
the next release, but for the moment I suppose something like this should work:

    HOGDescriptor hog = new HOGDescriptor(); 
    FloatPointer f = HOGDescriptor.getDefaultPeopleDetector();
    CvMat defaultSVM = CvMat.createHeader(f.capacity(), 1, CV_32FC1);
    defaultSVM.data_fl(f);
    hog.setSVMDetector(defaultSVM);

Let me know if this works! thanks

Hi, Samuel,

I have tried your code.
it works somehow .

CvRect found = null;
hog.detectMultiScale(image, found, 0, cvSize(8, 8), cvSize(32, 32),1.05, 2);

But hog generally returns null found. sometimes it crashes if you increase the 
upper limit of the window size.

I have run the peopledetect application from cpp sample,even the same input 
images don't have the same results.

Well, this works just fine here:
    CvRect found = new CvRect(null);
    IplImage img = cvLoadImage("gaitsetA-gait2.jpg");
    hog.detectMultiScale(img, found, 0, cvSize(8,8), cvSize(32,32), 1.05, 2);
    System.out.println(found);

I get (67, 7; 71, 142) on this image 
http://www.cbsr.ia.ac.cn/images/gaitsetA-gait2.jpg which looks about right.

Hi Samuel, 

Why is "found" in "hog.detectMultiScale" a single CvRect rather than a vector 
of CvRect's, as is specified in the following link? 
http://opencv.itseez.com/modules/gpu/doc/object_detection.html

Is there a way to get all CvRect's that are found by "hog.detectMultiScale" in 
javacv?

Fixed in latest release!

@zanetu, a CvRect object is a Pointer, which can be a native array. Just check 
Pointer.capacity() and use Pointer.position() functions as shown in the 
README.txt file, and please post your questions on the mailing list next time, 
thank you!

Thanks a lot.
Sorry for the inconvenience that was caused. I'll post on the mailing
list next time.

Hi samule can you help me?

Hi samuel what is the code for this?.. Plese gave me the source code in java...

hi samuel ,
can you help me ? can u mail me the source code of human detection using hog in 
java ?
thankx.

@elmarrhex @AKKI There's some C++ sample here:
https://github.com/Itseez/opencv/blob/2.4/samples/cpp/peopledetect.cpp
Please post your questions on the mailing list if possible, thanks!
