[wee chang]

Hi,
IplImage* m_image = m_camera.GetFrame().GetImage();
IplImage* image0 = m_canvas.GetImage();

cvCvtColor(m_image, image0 , 20); //constant 20 = BGR2HGV

i got error "In function cvCvtColor(): Bad Number of channels"

anyone knows the problem?? or i did the wrong way...pls advice

Thanks!!!

Hi,

I don't understand why you are using m_camera.GetFrame().GetImage() to get
original image if you are using cvcamdemo example.
You can just use "image" for original image and creating new variable with
IplImage structure for conversion RGB to HSV.
If you don't find the function for creating, let me know.
For error part, could you try to set the parameter to CV_BGR2HSV?

Thanks
