Curve motion constraint equation and its applications

Abstract

To understand the parallel computation of optic flow, the author introduces a novel algorithm to compute the flow field at certain locations in the image. These locations are on the gradient edges, called seeds. The proposed curve motion constraint equation provides additional constraints to fully and locally estimate the flow field at seeds. Initial computational experiments have used the improved local flow as the initial input to E.C. Hildreth's algorithm (1984). Results show that Hildreth's method is about ten times slower than the one proposed.<>
