Schooling has been observed in over 4000 species of fish(Shaw, 1962). The advantages of schooling may relate to reproduction, predator avoidance, feeding, learning, or energy conservation(Breder, 1959;Radakov, 1973). Models have been developed, based on theories of search, which show that there...
1a, a projector located 226 cm over the experimental arena casts a dynamic light field at 30 Hz onto the bottom of the tank. An IR camera placed 180 cm over the tank records images at 30 Hz as shown in Fig. 1. A cropped sample image of the light is shown in Fig. 1b,...
The algorithm includes: 1) seabed identification and removal; 2) bubble layer removal; 3) choosing a threshold for fish backscatter and setting all pixels below it to 0; and 4) identifying the school boundaries and smoothing the images by using morphological operations....
Smalyukh, in particular, is excited about how unpredictable the schools ofsolitonscan be. He said that such behavior could lead to different kind of interactive display technology, one in which the images that you see on a screen aren't necessarily pre-programmed but appear and shift according ...
The aggregate motion of a flock of birds, a herd of land animals, or a school of fish is a beautiful and familiar part of the natural world. But this type ... CW Reynolds,H Flocks - ACM 被引量: 1.2万发表: 1987年 Flocks, Herds, and Schools: A Distributed Behavioral Model A techniq...
Tuna fish school detection provides information on the fishing decisions of purse seine fleets. Here, we present a recognition system that included fish shoal image acquisition, point extraction, point matching, and data storage. Points are a crucial characteristic for images of free-swimming tuna ...

the area most severely damaged by the storm surge of Hurricane Iota. The extensive tree mortality is evident in both a Sentinel-2 satellite image and the ground panoramic picture taken during field verification. According to the visual information provided by these images, it is possible to confir...
