It means that for a particular frame in the video to be marked as blank, 95% of the frame must have a light value less than 0.1 (0: all black, 1: all white).

For bars, it compares all pixels in the frame against a "perfect bar picture", and the number of pixels that differs with more than 0.05 has to be below 10%.
