Title
Accurate optical flow in noisy image sequences
Abstract
Optical Flow estimation in noisy image sequences re- quires a special denoising strategy. Towards this end we introduce a new tensor-driven anisotropic diffusion scheme which is designed to enhance optical-flow-like spatio- temporal structures. This is achieved by selecting diffusiv- ities in a special manner depending on the eigenvalues of the well known structure tensor. We illustrate how the pro- posed choice differs from edge- and coherence-enhancing anisotropic diffusion. Furthermore we extend a recently dis- covered discretization scheme for anisotropic diffusion to 3D data. An automatic stop criterion to terminate the diffu- sion after a suitable time is given. The performance of the introduced method is examined quantitatively using image sequences with a substantial amount of noise added.
