    Abstract: A post-processing method for reducing artifacts in block-coded digital images, characterized by providing for: dividing an input image (In) into a plurality of image blocks (IB); for each image block (IB), estimating global features (GF) of said image block providing information on an average content of image edges along the horizontal and vertical directions of said image block (IB); for each pixel (Px) of an image block (IB) under examination, estimating local features (LF) for said pixel (Px) providing information on the content of image edges along the horizontal and vertical directions of an image area near said pixel (Px); modifying the value of said pixel (Px) according to both said global features (GF) of the image block (IB) to which said pixel (Px) belongs and said local features (LF) of the image area near said pixel (Px).

    Abstract: The level of Gaussian noise in a memory field being scanned by rows is reduced by reconstructing each pixel by fuzzy logic processors, the latter processing the the values of pixels neighbouring the pixel being processed and belonging to a processing window defined by the last scanned row and the row being scanned, thus minimizing the memory requisite of the filtering system to a single row. The system perform an adaptive filtering within the current field itself and does not produce edge-smoothing effects as in prior adaptive filtering systems operating on consecutive fields.

    Abstract translation: 通过用模糊逻辑处理器重建每个像素来减少由行扫描的存储器场中的高斯噪声的水平，后者处理与正在处理的像素相邻的像素的值，并且属于由最后扫描行定义的处理窗口， 该行被扫描，从而将过滤系统的存储器必需度最小化到单个行。 该系统在当前字段本身内执行自适应滤波，并且不产生像在连续字段上操作的先前的自适应滤波系统中的@边缘平滑效应。

    Abstract: A method of compressing digital images acquired in CFA (colour filter array) format (3) that utilizes optimised quantization matrices. The method, basing itself on the statistical characterization of the error introduced during the processing phase (4,5) that precedes compression (6), appropriately modifies the coefficients of any initial quantization matrix, even of a standard type, obtaining a greater compression efficiency without introducing further quality losses.

    Abstract: Digital video signals, such as the signals generated by an image sensor (1) in a Bayer format, in which the pixels of each line are alternatively coded with two colours, and then converted into an encoded format. In the encoded format, the pixels of the digital video signals are reordered into sets of adjacent pixels, such that the sets group pixels coding the same colour. The encoded signal data is suitable for transmission over a bus (B) in conditions of reduced switching activity.
