Table 3 Results of frequency analysis in video data of rats: Number of signals (N) and success rate (SR) in % for the categories extraction method, different body parts and color channel. Success rate was determined by dividing the number of successfull achr detections by the number of analysed signals in that category. E.g. \(SR = \frac{N_{\textrm{HR detectedTail}}}{N_{\textrm{Tail}}}\), where \(N_{\textrm{HR detectedTail}}\) is the number of signals retrieved from tails where the achr was successfully detected, and \(N_{\textrm{Tail}}\) the number of signals retrieved from tails.
