http://www.labbookpages.co.uk/software/imgProc/otsuThreshold.html WebbShui-gen Wei et al. introduced the Otsu algorithm to the optical flow method of target detection. They first normalized the optical image flow as a grey image. Next, they used the Otsu algorithm to translate it into a binary image. The Otsu algorithm is the primary method of the optical flow method for motion target detection [21,22,23,24].
