Decomposition of Optical Flow on the Sphere [PDF]

open access: yes, 2014
We propose a number of variational regularisation methods for the estimation and decomposition of motion fields on the $2$-sphere. While motion estimation is based on the optical flow equation, the presented decomposition models are motivated by recent ...
