oh,so your source image is color image right. at first you must define your yellow pixels ,the range r,g,b.because those color combine yellow color. Then you can split your source image rgb ,finally subtract each color and combine the result. CV_8UC1 for gray image. and CV_8UC3 for color image

Please stick to one question if the general goal is the same. I will close this one down, focus all your questions about yellow pixels together here!
