I3Dを用いたツシマヤマネコの発情兆候検出

抄録

In recent years, breeding programs for the endangered Tsushima leopard cat are being conducted in various parts of Japan. However, there is a risk of fighting if males and females are allowed to live together during the nonestrus period. Therefore, it is necessary to detect the signs of estrus in advance in order to prevent injuries caused by fighting in the Tsushima leopard cat. However, currently, this is done manually by zookeepers, which requires a great deal of labor. In this study, we aim to automatically recognize the signs of estrus in the Tsushima cat with the cooperation of zoos. We extend the two-stream I3D to detect the estrus behavior from surveillance videos. Our results show that the estrus sign of Tsushima leopard cat can be effectively detected by using I3D.
