MVA '92 IAPR Workshop on Machine Vision Applications Dec. 7-9,1992, Tokyo A Fast Object Flow Estimation Method based on Spacetime Image Analysis

This paper presents a fast object flow estimation method based on spacetime image analysis. We introduce the Ortho-sectioning method which uses the object's geometry on two slices of spacetime volume to estimate the object's flow. The one slice image method which can estimate binary flow direction is also described. An experimental realtime system using the method is built on a workstation and experimental results are shown.
