Optical flow from 1-D correlation: Application to a simple time-to-crash detector

Abstract

In the first part of this article we show that a new technique exploiting 1-D correlation of 2-D or even 1-D patches between successive frames may be sufficient to compute a satisfactory estimation of the optical flow field. The algorithm is well suited to VLSI implementations. The sparse measurements provided by the technique can be used to compute… (More)
