Hi all. Can any one explain why OpenCV using BGR colour space instead of RGB. We all know that RGB is the convenient colour model for most of the computer graphics and also the human visual system works in a way that is similar to an RGB colour space. Is there any reason behind OpenCV BGR colour space ?.

Thanks in advance.......

I recommend to use Qt , you can find lot of tutorial in net.

Use Mat::split, which splits multi-channel image into several single-channel arrays.

Example:

Mat src = imread("img.png",CV_LOAD_IMAGE_COLOR); //load  image

Mat bgr[3];   //destination array
split(src,bgr);//split source  

//Note: OpenCV uses BGR color order
imwrite("blue.png",bgr[0]); //blue channel
imwrite("green.png",bgr[1]); //green channel
imwrite("red.png",bgr[2]); //red channel

You are right, thanks for noticing :). I will edit it.

Hi guys, My goal is to draw a line on the boundary between the grass and concrete as in the image. However, I am having difficulty cuz the grass is too jagged. What function should I use in this case?

Hi all I am a beginner in Android but familiar with OpenCV. My question is does Android support all the functions we normally used in our PC like VideoCapture, createTrackbar, cvNamedWindow, CvShowImage, etc. If Android doesn't support all those functions and classes, where should I refer to learn more about supported function and class. Where should I get a good documentation about all these things.

Thanks
