Multiple tracking methods are widely required in biology field, in particular neuroethology and ecology field. Biology researches have to observe target behavior with recording video and have to spend much time for analyzing video data afterward. Here we focus on fighting behavior between male crickets. Fighting behavior is one of the common behaviors in animals. Animals usually fight for resources like foods, territory, mating partner and so on. During a fight, animals modify their aggressive motivation and behavior. In order to understand how they alter their motivation and behavior, we need to analyze the detail of the time sequence of the fighting. Therefore, we propose the video image processing method for automated observation, which enable us to observe and measure the behavioral characteristics of plural crickets simultaneously. Finally, through experiments we prove the effectiveness of our method.
