One of the weaknesses of the color restoration/balancing algorithm, is that it requires sufficient amounts of red, green, and blue (or their mixes) to be in a frame or image, for it to give accurate results. The Luke meets Obi-Wan frames are particulary challenging, because the colors are supposed to be skewed towards the oranges. I’ve been considering how to deal with such frames or sequences. One way to deal with this, is to find areas in the frame that are supposed to be balanced, namely the grey/white areas. Calibrating the color restoration/balancing algorithm on the white/gray parts of R2-D2 for example gives much improved results:
