Efficient Background subtraction with OpenCV

Question

I want to do background subtraction in a video file using OpenCV method. Right now I'm able to do background subtraction, but the problem is that I couldn't get the output in color mode. All the output after subtracting the background is coming in grayscale color mode :(. I want to get the color information to the foreground which is the resulting output after background got subtracted.

Can I do it using masking technique?? like the following procedure which I'm thinking about.

1. Capture Input -- InputFrame (RGB)
2. Process InputFrame
3. Subtract background, store foreground in TempFrame (which is coming in grayscale :( )
4. Create a mask using TempFrame
5. Apply the created mask to the InputFrame
6. Get colored foreground as OutFrame

I'm struck up with doing the masking using OpenCV. I'm just a very beginner in OpenCV. Please help me to overcome this.

Thanks in advance.

to reach a colored foreground just copy image by using foreground mask

// image.copyTo(foreground,foreground);
