摘要： An apparatus and method for video object generation and selective encoding is provided. The apparatus includes a detection module for detecting a first object in at least one image frame of a series of image frames; a tracking module for tracking the first object in successive image frames and segmenting the first object from a background, the background being a second object; and an encoder for encoding the first and second objects to be transmitted to a receiver, wherein the first object is compressed at a high compression rate and the second object is compressed at a low compression rate. The receiver merges the first and second object to form a composite image frame. The method provides for detecting, tracking and segmenting one or more objects, such as a face, from a background to be encoded at the same or different compression rates to conserve bandwidth.

摘要： A method for the self-calibration of the position of a set of sensors of acoustic signals includes a set of sources of acoustic events provided for generating acoustic waves; measuring times of flight of the acoustic events between each source of acoustic events and each microphone; and reconstructing the positions of the set of sensors and the positions of the sources of acoustic events through a maximum-likelihood estimation procedure executed on the basis of the measured times of flight. Times of emission of the acoustic events are acquired and times of flight are obtained. Distances are calculated between the sources and the sensors. A matrix of estimated positions of the sensor microphones and a matrix of estimated positions of the sources of events are calculated.
