Client Appl | Search Application |
Summary | This component generates compressed spatio-temporal region data from alpha-map images. This component supports two trajectory types: the FigureTrajectory and the ParameterTrajectory. The FigureTrajectory describes spatio-temporal regions by trajectories of representative points of refernce region. The ParameterTrajectory describe spatio-temporal regions by trajectories of motion parameters. The TemporalInterpolationD is used for describing trajectories. |
Strong Points | Full automatic extracting region data from a sequence of alpth map image. |
Limitations | The maximum number of NumberOfReferenceRegions parameter is 10. The maximum number of Vertices in FigureTrajectory is 30. |
Known Problems | NONE |
Parameters | Trajectory = Select 'FigureTrajectory', 'ParameterTrajectory' or 'MediaTime' to specify trajectory type. StartFrame = Spacify a frame number of a first image of an input image list. EndFrame = Specify the maximum frame number. VerN = Specify a vertices number of a polygon gerenated by the ExtractionTool. Depth = Specify a value of 'Depth' parameter. |
