Maybe using simply the nearest non-logo pixel would be a good initial
guess. Another option is using both approaches - compare the masked
frames, and if they are close in some reasonable metric, use the
previous result as an initial guess, and go for the nearest pixel
otherwise (which would usually mean that the scene has changed and the
previous result is rather useless).
