Thanks for your response Balaji R
In case anyone is interested here is how I solved it:
Mat ConvertBGR2Bayer(Mat BGRImage) {
/*
Assuming a Bayer filter that looks like this:
# // 0 1 2 3 4 5
/////////////////////
0 // B G B G B G
1 // G R G R G R
2 // B G B G B G
3 // G R G R G R
4 // B G B G B G
5 // G R G R G R
*/
Mat BayerImage(BGRImage.rows, BGRImage.cols, CV_8UC1);
int channel;
for (int row = 0; row < BayerImage.rows; row++)
{
for (int col = 0; col < BayerImage.cols; col++)
{
if (row % 2 == 0)
{
//even columns and even rows = blue = channel:0
//even columns and uneven rows = green = channel:1
channel = (col % 2 == 0) ? 0 : 1;
}
else
{
//uneven columns and even rows = green = channel:1
//uneven columns and uneven rows = red = channel:2
channel = (col % 2 == 0) ? 1 : 2;
}
BayerImage.at<uchar>(row, col) = BGRImage.at<Vec3b>(row, col).val[channel];
}
}
return BayerImage;
}
