“…In previous studies, the movements of insect antennae were measured by manually determining their position and angle for each frame of video or using phototransistors, which register the movement of the antennae (Erber and Kloppenburg, 1995;Erber et al, 1993;Okada and Toh, 2004). Recently, video analysis technologies have advanced, and methods for automatically tracking the movement of body parts of the honey bee have been reported, such as tracking the marked colors at the tip of the antennae or separating the outline of the antennae from the background by image processing (Cholé et al, 2015;Cholé et al, 2022;Roy Khurana and Sane, 2016). In addition, a markerless posture-tracking tool using deep learning, DeepLabCut (Mathis et al, 2018;Nath et al, 2019), has been widely used in various research fields, such as ecology and neuroscience (Mathis and Mathis, 2020), and is becoming recognized as a powerful tool that does not require special devices or expertise, in addition to being noninvasive and robust in analyzing .…”
