Research of image recognition allows for improvements in animal welfare compliant and increase in data yield in animal experiments. One application for improvements are the so-called rotational tests with rats in Parkinson research. Here, the Rat Rotation Detection System (RRDS) frees the rat from the usually used breast belt while achieving similar results as the previous system, with a difference of 12.4 %. RRDS basically consists of an off-the-shelf camera combined with a YoloV4″=Neural″=Network, which detects the coordinates of the head, the tail, and the torso of the rat. With these coordinates, RRDS calculates two vectors, which are further used to calculate the rotation of the rat. The RRDS is a step towards improved animal welfare and more accurate results in animal experimentations. |
