Five metrics for scene change detection in video sequences are presented. Metrics previously applied to this problem are surveyed, and are quantitatively compared to the new metrics. Results show that the proposed metrics are superior.
Rhodobacter sphaeroides is a photosynthetic bacterium which swims by rotating a single flagellum in one direction, periodically stopping, and reorienting during these stops. Free-swimming R. sphaeroides was examined by both differential interference contrast (DIC) microscopy, which allows the flagella of swimming cells to be seen in vivo, and tracking… (More)
