Real-time parallel computation of disparity and optical flow using phase

1996 
A phase-difference-based algorithm for disparity and optical flow estimation is implemented on a TI-C40- based parallel DSP system. The module performs real-time computation of disparity maps on images of size 128 x 128 pixels and computation of optical flows on images of size 64 x 64 pixels. This paper describes the algorithm and its parallel implementation. Processing times required for the computation of disparity maps and velocity fields and mea- sures of the algorithm's performance are reported in detail.
