National audienceIn this paper we study the estimation of dense 3D motion fields over non-rigidly moving surface observed by multicamera systems. The motivation arises from multi-camera applications that require motion information in order to perform tasks such as surface tracking or segmentation. To this aim, we present a novel framework that allows to to efficiently compute dense 3D displacement fields using low level visual cues and geometric constraints. The main contribution is a unified framework that combines flow constraints for small displacements with temporal feature constraints for large displacements and fuses them over the surface using local rigidity constraints. The resulting linear optimization problem allows for variationa...
