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.

For example, in some embodiments, an apparatus is provided that includes: (a) a background model generation unit for extracting a codebook from multi-view background images and generating codeword mapping tables operating in conjunction with the codebook; and (b) a foreground and background segmentation unit for segmenting multi-view images into foreground and background using the codebook and the codeword mapping tables.
摘要:
An apparatus for evaluating the performance of speech recognition includes a speech database for storing N-number of test speech signals for evaluation. A speech recognizer is located in an actual environment and executes the speech recognition of the test speech signals reproduced using a loud speaker from the speech database in the actual environment to produce speech recognition results. A performance evaluation module evaluates the performance of the speech recognition by comparing correct recognition results answers with the speech recognition results.
