Abstract:
An apparatus for compressing low-complexity 3D mesh, includes: a data analyzing unit for decomposing data of an input 3D mesh model into vertices information, property information representing property of the 3D mesh model, and connectivity information between vertices constituting the 3D mesh model; a mesh model quantizing unit for producing quantized vertices, property and connectivity information of the 3D mesh model by using the vertices, property and connectivity information; and a sharable vertex analysis unit for analyzing sharing information between shared vertices of the 3D mesh model. Further, the apparatus includes a data modulation unit for performing a circular DPCM prediction by using quantized values of the consecutive connectivity information of the 3D mesh model; and an entropy encoding unit for outputting coded data of the quantized vertices and property information, and differential pulse-code modulated connectivity information as a bitstream.
Abstract:
An apparatus for 3D mesh compression based on quantization, includes a data analyzing unit (510) for decomposing data of an input 3D mesh model into vertices information (511 ) property information (512) representing property of the 3D mesh model, and connectivity information (515) between vertices constituting the 3D mesh model: and a mesh model quanitzing unit (520) for producing quantized vertices and property information of the 3D mesh model by using the vertices, property and connectivity information (511, 512, 513).

Abstract:
A multimedia application system uses metadata for sensory devices. The system includes: a sensory-device engine for generating a sensory device command (SDC) for controlling the sensory devices based on sensory effect information (SEI) generated to represent sensory effects by using the sensory devices depending on video contents, user preference information (UPI) of the sensory devices and device capability information (DCI) indicative of reproducing capability of the sensory devices; and a sensory-device controller for controlling sensory devices to perform sensory effect reproduction in response to the generated SDC.
