Table II.
The algorithm is able to select ROIs that accurately track the motion of the camera. Results from the analysis of nine videos from both the parabolic flight and intentional blinking video collections are shown. errorRMS reported are the mean of the top 10 worthy ROIs determined for each trial. By the second generation, the average errorRMS is 0.75º. The average improvement between the first and second generation is 0.09º or 11% (p<0.07; paired one-tail t-test).
