RGB video source problem

[Reena24]

Hi the PTAMM code started to work finally in Windows and I was finally able to get the video source from usb web cam using the code

include “VideoSource.h”

//#include

using namespace CVD; using namespace std; using namespace GVars3; using namespace cv;

define OPENCV_VIDEO_W 640

define OPENCV_VIDEO_H 480

namespace PTAMM { VideoSource::VideoSource() { cout << " VideoSource_Linux: Opening video source…" <isOpened()){ cerr << "Unable to get the camera" << endl; exit(-1); } cout << " … got video source." << endl; mirSize = ImageRef(OPENCV_VIDEO_W, OPENCV_VIDEO_H); };

ImageRef VideoSource::Size() { return mirSize; };

void conversionNB(Mat frame, Image &imBW){ Mat clone = frame.clone(); Mat_& framep = (Mat&)clone; for (int i = 0; i < OPENCV_VIDEO_H; i++){ for (int j = 0; j < OPENCV_VIDEO_W; j++){ imBW[i][j] = (frame_p(i,j)[0] + frame_p(i,j)[1] + frame_p(i,j)[2]) / 3; } }

}

void conversionRGB(Mat frame, Image &imRGB){ Mat clone = frame.clone(); Mat_& framep = (Mat&)clone; for (int i = 0; i < OPENCV_VIDEO_H; i++){ for (int j = 0; j < OPENCV_VIDEO_W; j++){ imRGB[i][j].red = frame_p(i,j)[2]; imRGB[i][j].green = frame_p(i,j)[1]; imRGB[i][j].blue = frame_p(i,j)[0]; } } }

void VideoSource::GetAndFillFrameBWandRGB(Image &imBW, Image &imRGB) { Mat frame; VideoCapture* cap = (VideoCapture)mptr; cap >> frame; conversionNB(frame, imBW); conversionRGB(frame, imRGB); } }

But the video source for PTAMM is black and white how do I get the an RGB video source instead of a gray image as video source. I think I need to add the line cvCvtColor(&frame,&frame,CV_GRAY2BGR);

but it dosnt work cause I get OpenCV assertion error. Could someone tell me how do I get RGB type video Input Source.

OpenCV video capture capture frames in RGB format by default, so there is no need to make any conversion if you need RGB data for your algorithm.
