OK, I'm trying to edit my question, I've done the segmentation but when I used cv::scalar for the color it gives me solid background color RGB which means the object will disappear. So my objective is to make the segmented area looks like the attached picture as green tint so is there any tool in opencv that can achieve this?

Thanks
