Thank you Der Luftmensch

Hi, can you please refer any link or tutorial to train my data of cup detection.

I don't know what is the movement of your hand in video, but suppose, movement is from right to left and left to right very fast, then you may lose the hand movement completely.

Thank you Der Luftmensch. I think it is a good suggestion for me to try TensorFlow.

I am new in opencv. I am trying to make cup detector like face detector in opencv. But I see the positive samples of face detector, there is particular pattern of eyes, nose and mouth, so there is, somewhat all, positive samples have same pattern. But cups don't have the same pattern on it. Some cups are plan and some have graphics on it. So suggest me any idea how to take samples and implement it.

Hi, as given in the document of opencv, convertTo converts an array to another data type with optional scaling. And it is clearly mentioned that the number of channels of output and input must be same. rtype – desired output matrix type or, rather, the depth since the number of channels are the same as the input has; if rtype is negative, the output matrix will have the same type as the input.

Hi, I have found the solution. Actually the problem was nothing but just the images. The common area in the images was not enough, so after trying with the different images, I got the stitched image.

Hi, I have a simple code of stitching image.

int main() { Mat pano; vector <mat> imgs;

imgs.push_back ( imread ("2.jpg",CV_LOAD_IMAGE_COLOR));
imgs.push_back ( imread ("3.jpg",CV_LOAD_IMAGE_COLOR));
Stitcher stitcher = Stitcher::createDefault(true);
Stitcher::Status status = stitcher.stitch(imgs, pano);
if (status != Stitcher::OK)
{
    cout << "Can't stitch images, error code = " << int(status) << endl;
    return -1;
}
imshow("result_name", pano);
waitKey(0);

}

I have 2.jpg and 3.jpg is the present working directory. I am running this code, I am getting error : Can't stitch images, error code = 1 Can anybody help me to get rid of this error?

Here 2.jpg and 3.jpg are the cropped images from the single image.

Hi, take the biggest contour instead.

Ok. Thank you

linux 14.04, opencv 3.1.0 and actually, camera is underdevelopment. So if would solve the issue, I will let you know.

set() is always returning true and while getting using videoCapture::get(), it is returning the same value which is been set by set().

Thanks for immediate responding, but actually I am changing the focus value of the camera and not able to get range.

Hi, Is there any API in opencv ( or any programmatic way ) to get the range of a particular property of VideoCapture class like exposure or brightness.

Hi, give the path of the opencv library with -L flag.

Actually, this error comes because of dynamic compile time linking, so in order to link it we can use -lopencv_imgproc in command line.

yeah, I too suggested imgproc only.

If the error is still there, then first you should include header file #include "opencv2/imgproc.hpp" and the compile your code as g++ -L/usr/local/lib -o "ClaheTeste1" ./main.o -lopencv_imgcodecs -lopencv_highgui -lopencv_core -lopencv_imgproc
