HSV image color thresholding
显示 更早的评论
how can we filter out (turn black) any pixel that is not the color of the lanes? (in this case white or yellow.).I have converted the image in HSV from RGB.

What lanes? Basically just create a mask of where the white or yellow pixels are that you want to blacken, then do this:
% Mask the image using bsxfun() function to multiply the mask by each channel individually.
maskedRgbImage = bsxfun(@times, rgbImage, cast(mask, 'like', rgbImage));

See road following algorithms here: http://www.visionbib.com/bibliography/contentsactive.html#Active%20Vision,%20Camera%20Calibration,%20Mobile%20Robots,%20Navigation,%20Road%20Following Sorry, I don't have code for any of them since autonomous navigation is not my field, but you can ask the authors.
