    In the paper, a multichannel edge enhancing filter (MEEF) based on the vector median is introduced for enhancing degraded edges in color images. An input multichannel signal is filtered with three subfilters, and the final output is determined by comparing the outputs of the subfilters and their vector median. Root signal and edge enhancement properties of the MEEF are examined in detail. In addit... View full abstract»

    Examines the distinctive features of 2D diamond-shaped filters, a class of filters quite important for video interpolation/decimation. The geometrical interpretation of linear programming is proposed as an easy tool for understanding the characteristics of M-D FIR filters minimax optimal and the effects of the constraints most common in video application. The relationships between minimax error, f... View full abstract»

    A new hardware-oriented algorithm called the one-dimensional full search (1DFS) is presented for block-matching motion estimation in video compression. The simulation for this algorithm follows H.261 and MPEG international standards. In MPEG simulation, structures with 1-, 2- and 3-frame interpolation are compared. The performance of 1DFS is superior to that of other fast search algorithms. And it... View full abstract»

    A self-organization neural network architecture is used to implement vector quantization for image compression. A modified self-organization algorithm, which is based on the frequency-sensitive cost function and centroid learning rule, is utilized to construct the codebooks. Performances of this frequency-sensitive self-organization network and a conventional algorithm for vector quantization are ... View full abstract»

    This paper presents a simple approach to regulating the bit stream generated by the hybrid DPCM/DCT video codec so that the compressed bit stream at a variable rate can be transmitted over a fixed rate channel. Bit rate regulation is accomplished by appropriately quantizing the DCT coefficients where the quantization stepsize is obtained by multiplying a fixed weighting matrix by a scaling factor....

    The paper describes a multiple-template generalization of a newly developed approach for template matching by signal expansion into a set of non-orthogonal template-similar basis functions. The single-template method is proven to be equivalent to “restoration” of undegraded images using the Wiener filter and optimizes a new and more practically defined matching quality criterion that t...
