LEAD Video Auto Level Filter User Interface

The Auto Level Video filter performs color leveling on the individual R, G and B channels, treating each of the R, G and B channels as a separate entity, without changing colors. It makes the dark values darker and the light values lighter, which automatically enhances shadows and brightens the video stream. It also maximizes the tonal range of the image and enhances the contrast and intensity using the image's histogram and a color distribution-based algorithm.
