Abstract

It proposes a non-correlation, conceptually new, fast and efficient approach for DPIV, which takes the nature of flow into consideration. An incompressible affined flow model (IAFM) is introduced to describe a flow that incorporates constraints on the computation. This IAFM, combined with a modified optical flow method-named total optical flow computation (TOFC), provides a linear system solution to DPIV. Experiments on real images showed our method to be a very promising approach for DPIV.
