    • Abstract

       

      Two methods have been suggested to detect the direction (forward or backward) of uniform velocity motion along with identification of no motion positions with other intensity maxima positions in the reconstruction. The first method requires two continuous exposures while the other is a combination of one static and one continuous recording.
