    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 and a device for motion estimated and compensated Field Rate Up-conversion (FRU) for video applications, providing for: a) dividing an image field to be interpolated into a plurality of image blocks (IB), each image block made up of a respective set of image elements of the image field to be interpolated; b) for each image block (K(x,y)) of at least a sub-plurality (Q1,Q2) of said plurality of image blocks, considering a group of neighboring image blocks (NB[1]-NB[4]); c) determining an estimated motion vector for said image block (K(x,y)), describing the movement of said image block (K(x,y)) from a previous image field to a following image field between which the image field to be interpolated is comprised, on the basis of predictor motion vectors (P[1]-P[4]) associated to said group of neighboring image blocks; d) determining each image element of said image block (K(x,y)) by interpolation of two corresponding image elements in said previous and following image fields related by said estimated motion vector. Step c) provides for: c1) applying to the image block (K(x,y)) each of said predictor motion vectors to determine a respective pair of corresponding image blocks in said previous and following image fields, respectively; c2) for each of said pairs of corresponding image blocks, evaluating an error function (err[i]) which is the Sum of luminance Absolute Difference (SAD) between corresponding image elements in said pair of corresponding image blocks; c3) for each pair of said predictor motion vectors, evaluating a degree of homogeneity (H(i,j)); c4) for each pair of said predictor motion vectors, applying a fuzzy rule having an activation level (r[k]) which is higher the higher the degree of homogeneity of the pair of predictor motion vectors and the smaller the error functions of the pair of predictor motion vectors; c5) determining an optimum fuzzy rule having the highest activation level (r[opt]), and determining the best predictor motion vector (P[min]) of the pair associated to said optimum fuzzy rule having the smaller error function; c6) determining the estimated motion vector for said image block (K(x,y)) on the basis of said best predictor motion vector (P[min]).
