Extraction Yes
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

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.
