VELOCITY FIELD MEASUREMENT FROM IMAGE SEQUENCES

S. Ogata, K. Saza
Abstract:
We have improved a spatio-temporal correlation method to obtain velocity field from dynamic image. The new method can specify a certain image frame out of many sequential frames of a moving object and determine its 2-D velocity field on the basis of the specified frame. In addition, it enables us to avoid an edge effect of velocity field which appear at both ends of image row. The improvement has enhanced reliability and reduced computational time compared to other conventional methods.
