    Abstract: The invention concerns a device for processing a digital image comprising at least one contour region, including sharpness processing of the contour region. The sharpness processing includes converting data of the level of pixels of the contour zone into initial main data (step 2), ranging between a minimum value, for example 0 and a main value based on the amplitude of the contour, a sharpness sub-processing performed on said initial main data so as to obtain final main data (steps 3 to 10), and converting the final main data into final data of levels (step 11).

    Abstract: A method and apparatus of encoding digital video according to the ISO/IEC MPEG standards (ISO/IEC 11172-2 MPEG-1 and ISO/IEC 13818-2 MPEG-2) using an adaptive motion estimator. A plurality of global motion vectors are derived from the motion vectors of a previous picture in a sequence, and the global motion vectors are analyzed to determine motion characteristics. The video encoding is arranged to enable switching among different types of local motion estimators based on the motion characteristics of the moving pictures sequence. This gives rise to a motion estimation algorithm that can adaptively change its search range, search area and block matching scheme to suit different types of moving sequences.

    Abstract: Perceptual audio coder refers to audio compression schemes that exploit the properties of human auditory perception. The coder allocates the quantization noise below the masking threshold such that even with the bit rate limitation, the noise is imperceptible to the ear. These distortion and bit rate requirement makes the bit allocation-quantization process a considerable computational effort. One method includes incrementally adjusting a global gain according to a gradient. The gradient could be adjusted each time the number of bits used to represent a quantized value is counted. Another method includes limiting a rate controlling parameter to a predetermined number of loops. The method could also include deriving a global gain to ensure exit from the loop. Accordingly, embodiments of the present disclosure provide a fast and efficient method to derive the rate controlling parameter and can be applied to generic perceptual audio encoders where low computational complexity is required.

    Abstract: A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.
