Completely automated end-to-end method and system for markerless motion capture performs segmentation of articulating objects in Laplacian Eigenspace and is applicable to handling of the poses of some complexity. 3D voxel representation of acquired images are mapped to a higher dimensional space (k), where k depends on the number of articulated chains of the subject body, so as to extract the 1-D representations of the articulating chains. A bottom-up approach is suggested in order to build a parametric (spline-based) representation of a general articulated body in the high dimensional space followed by a top-down probabilistic approach that registers the segments to an average human body model. The parameters of the model are further optimized using the segmented and registered voxels.

A method is disclosed to generate, while preserving text, image, transactional and embedded presentation constraint information, a minimum set of simplified and navigable web contents from a single web document that is oversized for targeted smaller devices. The method includes a parser, a content tree builder, a document tree builder, a document simplifier, a virtual layout engine, a document partitioner, a content scalar and a markup generator. The parser generates markup and data tags from an HTML source document. The builder constructs a content tree. The simplifier transforms the document tree into an intermediate one defined by a subset of XHTML tags and attributes. Layout constraints, including size, area, placement order, and column / row relationships, are calculated for partitioning and scaling the document tree into sub document trees with assigned navigation order and hierarchical hyperlinks. A simplified HTML document is then generated with the markup generator.
