Optical Flow on Evolving Surfaces with Space and Time Regularisation
arXiv:1310.0322 · doi:10.1007/s10851-014-0513-4
Abstract
We extend the concept of optical flow with spatiotemporal regularisation to a dynamic non-Euclidean setting. Optical flow is traditionally computed from a sequence of flat images. The purpose of this paper is to introduce variational motion estimation for images that are defined on an evolving surface. Volumetric microscopy images depicting a live zebrafish embryo serve as both biological motivation and test data.
