Abstract: A method for improving the perception of an image may include performing a main separation of the pixels of the image into two categories, one corresponding to pixels of a flat zone, and the other corresponding to pixels of a textured zone. The method may also include processing the pixels of each category according to a method optimized according to the type of zone. Before the main separation step, a preliminary separation of the pixels may be performed into one category of normal pixels intended for the main separation step, and one category of singular pixels, with the criterion for selecting the singular pixels being adapted to identify pixels that would be wrongly identified as pixels of a textured zone. The singular pixels may then be processed according to a method adapted to their nature.

Abstract: An integrated MEMS structure includes a driving assembly anchored to a substrate and actuated with a driving movement. A pair of sensing masses suspended above the substrate and coupled to the driving assembly via elastic elements is fixed in the driving movement and performs a movement along a first direction of detection, in response to an external stress. A coupling assembly couples the pair of sensing masses mechanically to couple the vibration modes. The coupling assembly is formed by a rigid element, which connects the sensing masses and has a point of constraint in an intermediate position between the sensing masses, and elastic coupling elements for coupling the rigid element to the sensing masses to present a first stiffness to a movement in phase-opposition and a second stiffness, greater than the first, to a movement in phase, of the sensing masses along the direction of detection.

Abstract: An embodiment of a receiver includes a channel estimator and a data-recovery unit. The channel estimator is configured to determine a characteristic of a channel over which a first signal, which is received simultaneously with a second signal, propagated, the first and second signals respectively having first and second components that include approximately a frequency. And the data-recovery unit is configured to recover data from the first signal in response to the determined channel characteristic. For example, such a receiver may be able to receive simultaneously, and over the same channel space, orthogonal-frequency-division-multiplexed (OFDM) signals that include one or more of the same subcarrier frequencies, and to recover data from one or more of the OFDM signals despite the frequency overlap. A receiver with this capability may allow an increase in the effective bandwidth of the channel space, and thus may allow more devices to simultaneously share the channel space.

Abstract: One or more embodiments to iteratively detect and decode data transmitted in a wireless communication system, featuring a MIMO detector and a soft input soft-output error-correction-code decoder. More specifically, a method suitable for iterative detection and decoding schemes is proposed, which is able to output near optimal bit soft information processing efficiently given input bit soft information. First, a transmitting source is selected as a reference layer, wherein the associated symbol represents a reference transmit symbol. Subsequently, a set of candidate values are identified for the reference transmit symbol. For each candidate value a candidate transmit sequence is estimated through a novel spatial decision feedback equalization process based on both Euclidean distance metrics and the a-priori soft information provided by the SISO ECC decoder. The novel DFE technique uses a novel bit metric.
