The impact of different thresholding level on identification of the mice in the video frames. a Increase of threshold from 0.5 to 0.8 gradually improved the signal/noise ratio of the mice images. b The identification of mouse in a video frame as marked by the color ovals at the threshold of 0.5 (left) or 0.75 (right). c The mouse trajectory plot of the mice with the threshold of 0.5 (left) or 0.75 (right)
