摘要： A system for localizing an object of interest in a monitored space includes a plurality of capacitive sensors for sensing changes in the status of a space, adapted to electrically interact in a contactless way with a ground surface so as to provide a capacitance varying on the basis of such changes, and adapted to detect at least a time evolution of the capacitance and to produce a capacitance-depending signal, a filtering unit configured for reducing the noise level in the time evolution of such capacitance by filtering the capacitance-depending signal provided by the capacitive sensors, so that corresponding filtered signals are produced, and a central device in signal communication with the capacitive sensors. The central device is configured for acquiring the filtered signals of each capacitive sensor, and for determining the position of the object of interest inside the space by inferring at least a distance of the object on the basis of the filtered signals acquired from at least one of the sensors detecting the object, and by combining the at least a distance with positional data defining the positions of the plurality of capacitive sensors in the monitored space.

摘要： A method for encoding a raw lenselet image includes a receiving phase, wherein at least a portion of a raw lenselet image is received, the image including a plurality of macro-pixels, each macro-pixel having pixels corresponding to a specific view angle for the same point of a scene, and an output phase, wherein a bitstream having at least a portion of an encoded lenselet image is outputted. The method has an image transform phase, wherein the pixels of said raw lenselet image are spatially displaced in a transformed multi-color image having a larger number of columns and rows with respect to the received raw lenselet image, wherein dummy pixels having undefined value are inserted into the raw lenselet image and wherein the displacement is performed so as to put the estimated center location of each macro-pixel onto integer pixel locations. Moreover, the method includes a sub-view generation phase, wherein a sequence of sub-views is generated, said sub-views having pixels of the same angular coordinates extracted from different macro-pixels of the transformed raw lenselet image. Finally, the method has a graph coding phase, wherein a bitstream is generated by encoding a graph representation of at least one of the sub-views of the sequence according to a predefined graph signal processing technique.
