觀察細節

Two videos of a bird flycatching. Actually one video, the first version cropped closer, and the second clip zoomed out to see more of the bird's flight. The bird caught a Tawny Emperor (butterfly) on its second flight. Notice how Cornell's algorithm chooses a frame that is not at the beginning of the video but rather 2-3 seconds into the video when the bird is away from the branch.
