A new framework for optical flow estimatio

الملخص EN

This paper presents a new meth©d to estimate optical flow in a differential framework.

The image sequence is first convolved with a spatiotemporal filter similar to those that have been used in other early vision problems such as texture and stercopsis.

The brightness constancy constraint can then be applied to each of the resulting images, giving in general an over determined system of equations for the optical flow at each pixel.

It is based on prediction of global flow field parameters, performs better than multi-resolution estimation methods and has been verified using standard test sequences as well as real-world data
