Swelling behaviour, solid state 29 Si NMR and other techniques indicate the formation of interconnected organic-inorganic materials. An in vitro apatite forming ability test performed on this new class of material compared with an equivalent class I poly(&egr;-caprolactone)-silica sol-gel hybrid

Unstructured crowded scenes are defined as those scenes where the motion of a crowd appears to be random with different participants moving in different directions over time. This means each spatial location in such scenes supports more than one, or multi-modal, crowd behavior. The case of tracking in structured crowded scenes, where the crowd moves coherently in a common direction, and the direction of motion does not vary over time, was previously handled in . This way any one location in the scene may support multiple crowd behavior modalities and can be used as prior information for tracking. Our approach enables us to model a diverse set of unstructured crowd domains, which range from cluttered time-lapse microscopy videos of cell populations in vitro, to footage of crowded sporting events.
