Depth maps play an important role in 3DTV applications for rendering stereo views. Most existing automatic algorithms cannot generate an acceptable quality of depth maps from a mono-channel video sequence. Proposed is a key-frame depth propagation algorithm, combining trilateral filtering to produce high-quality depth sequences. Experiment results show that the algorithm outperforms a well-known prior...
An approach to human action modelling and recognition in continuous action sequences is proposed. A star figure enclosed by a bounding convex polygon is used to effectively represent the extremities of the silhouette of a human body. Thus, human actions are recorded as a sequence of the star figure's parameters, which is then used for action modelling. To model human actions in a compact manner while...
