ABSTRACT
The trajectory of fish is an important index reflecting the behavioral characteristics of fish, which provide important information for studying the living habits of fish. Detection of fish behavior can provide useful information for improving production management and help farmers to observe fish behavior as an indicator for taking relative measures. Aquatic organisms are sensitive to changes in the surrounding environment and they will respond to these variables with unique movements or behaviors. A stereoscopic vision system was used to track the four to six groups of giant Danio aequipinnatus. Another proposed a method of tracking multiple bees with two cameras based on motion information. The method of background subtraction needs to provide to real-time “background image”. The frame difference between the background image and the image without fish detection is carried out to find the region where the fish is located.
