I have a video frame that contain lot of reflection from car headlight, this is the best result I can get while processing with HSV color space.

_{A)Original image B)value color space C)filtered image}

This is the code I used for filtering the frame. Is there any better way to remove the light reflection?

for i = 1:150 % Im using the 150th frame of the video

    frame = step(videoReader); % read the next video frame

    hsv = rgb2hsv(frame);

    h = hsv(:, :, 1); % Hue image.

    s = hsv(:, :, 2); % Saturation image.

    v = hsv(:, :, 3); % Value (intensity) image.

    thresholdframe = v;

    inversev = ~s;

    thresholdframe = v > 0.99;

    borderclearframe = imclearborder(s);

    BW2 = bwareafilt(thresholdframe,[400 500]);

end
