We propose a method that extracts sparse and spatially localized deformation modes from an animated mesh sequence. To this end, we propose a new way to extend the theory of sparse matrix decompositions to 3D mesh sequence processing, and further contribute with an automatic way to ensure spatial locality of the decomposition in a new optimization framework.(More)
In this paper we propose a real-time, low-complexity video rate control algorithm designed to obey buffer constraints. The algorithm is optimized for streaming and local recording applications in mobile devices. Today, most mobile phones include a digital camera that can be used to capture video. The on-phone processor technology has become powerful enough(More)
Transmission of hybrid coded video including motion compensation and spatial prediction over error-prone channels results in the well-known problem of spatio-temporal error propagation at the decoder. A widely accepted standard-compliant technique to enhance the quality of the decoded video significantly is the more frequent introduction of intra-coded(More)
Only recently it has become possible to label and visualize dopamine D2 receptors in the living human brain using an [123I]labeled ligand and the SPECT technique. Iodobenzamide (S(-)IBZM) is a substance with high affinity and high specificity for D2 receptors and was used in controls and in patients with different extrapyramidal disorders. After the i.v.(More)
