findContours is finding duplicate contours



Hello,

I am trying to do edge boundary detection on an image with some letters on it and the contours that are coming out have duplicates in them and it is messing up my algorithms. I would just remove them, but removing a contour and updating the hierarchy is pretty difficult. I'm wondering if there is something that I can do in order to prevent duplicates from being returned.

See my code: http://pastebin.com/Lhp3VFZh
The images: http://inky.ws/g/1vl

As you can see the letters Z, T, C (and more!) have more than one box around them.

extracting coordinates from a graph

Hi, 
I've just discovered OpenCV and starting to learn about CV in general. I was wondering if it is possible to
extract coordinates from an image of a graph using OpenCV. Pardon my ignorance on the topic.

Some insight would be greatly appreciated.
Thanks!

Hi,
i want to use the LUC feature with the LAB-Colorspace.
My problem is that LAB use a range between -128 up to 128.
How can i acces the negative values?

The paper on the QRIO robotics model is a good reference for this sort of
work.

never mind, it was surprisingly painless to compile. macports gave me a
bad impression after failing continuously.

This sort of info is in the "Core -> Basic Structures" part near the

Dear Friends ,
I want to make color representation in the hue-saturation plane of HSV image as shown in attached hueImg.jpg .Could any one please help me to do that . thanks 
One more issue is i can draw histogram of hue for intensity range 0 to 255 .but i wanna draw histogram of hue only that run from 0 to1 79 as opencv used as shown in the attached image hueInfo Img.jpg. .Could any one please guide me how to make it .thanks

Hi,

When I use the CPU version of opencv DFT I can specify the output as "DFT_REAL_OUTPUT" but this does not work with the GPU version of DFT.
If the input matrix is of type 32f the ouput type is 32f in the cpu version.
dft(padded1CPU, fft1CPU, DFT_REAL_OUTPUT);

When I use this for the gpu version: gpu::dft(padded1, fft1, padded1.size());

The fft1 becommes a 32f2 with two channels half the with of the cpu.
How can I merge this so the output is the same ouptut as in the cpu function?

Thanks

Hi everyone
I am working on MAC 10.8.6 ... my current version of openCV is 2.4.0 since I faced many problems ... I decide to update it to 2.4.2 (the latest version)when I install openCV, I install ffmpeg V11 before to make openCV deal with videos
So, do I need to remove every thing (ffmpeg with its requirements and openCV ), then install every thing again ?
or I can just install openCV 2.4.2 and old version will be replaced ! ??

does any one know??? :D
Thanks in advance
Seereen

Python x CPP: Diferents results from HOG pedestrian detector

Hi,

I'm receiving diferents results when running code throught python and cpp for HOG Pedestrian Detector. Am
I doing something wrong or is this a bug? Codes below. Ty

Python:
img = cv.LoadImage(sys.argv[1])
storage = cv.CreateMemStorage(0)
found = list(cv.HOGDetectMultiScale(img, storage, win_stride=(8,8), padding=(24,16), scale=1.05, group_threshold=2))
for i in found:
    xy, wh = i
    x, y = xy
    w, h = wh
    print str(int(frame)) + " " + str(x) + " " + str(y) + " " + str(w) + " " + str(h)

CPP:
HOGDescriptor hog;
vector<Rect> found;
IplImage* img = cvLoadImage(argv[1]);
hog.setSVMDetector(HOGDescriptor::getDefaultPeopleDetector());
hog.detectMultiScale(process, found, 0, Size(8,8), Size(24,16), 1.05, 2.0);
for( size_t i = 1; i < found.size(); i++ )
{
    Rect r = found[i];
    printf("%d %d %d %d %d\n", c, r.x, r.y, r.height, r.width);
}
