Abstract

In recent years, 3D recovery from motion has received a major effort in computer vision systems. The main problem lies in the number of operations and memory accesses to be performed by the majority of the existing techniques when translated to hardware or software implementations. This work proposes a parallel processor for 3D recovery from optical flow. Its main feature is the maximum reuse of data and the low number of clock cycles to calculate the optical flow, along with the precision with which 3D recovery is achieved. The results of such recovery, as well as those from processor synthesis are presented.
