+ | |||
+ | In general, optical flow describes a sparse or dense vector field, where a displacement vector is assigned to certain pixel position, that points to where that pixel can be found in another image. | ||
+ | In the context of scene flow estimation, which is performed on images with additional depth values, every pixel is assigned a depth displacement as well. | ||
+ | |||
+ | Since much of the structural information of a 3D scene gets lost in the imaging process, so does the motion information. The estimation of the " | ||
+ | Our group mainly focuses on optical flow estimation by means of variational methods, that allow a clear formulation of the assumptions incorporated into the estimation process and generally produce dense vector fields. | ||
