    The author presents an estimation scheme and its polyphase finite-duration impulse-response (FIR) filter implementation for the demodulation of composite chrominance signals into color difference components such as in-phase and quadrature-phase components. A decoding scheme with three-tap polyphase FIR filters is presented. The least square error estimators, which estimate the chrominance componen... View full abstract»

    The authors present sparse matrix representations for multidimensional Agarwal-Burrus nesting. It is shown that the resulting sparse matrices can be expressed in terms of tensor product decompositions. The formulations derived provide a highly compact representation of this approach to nesting. The tensor product approach also provides the needed structure to easily derive several variant schemes ... View full abstract»

    The design of image prefilters for error control is considered and seen to be closely related to the problem of designing antialiasing filters to precede signal decimation. Intrafield codes are introduced, some of which can be implemented with fewer than 1 multiplier per 100 pixels. These codes have a great advantage in a bandlimited TV environment over alternative error-control methods requiring ... View full abstract»

  • Two-dimensional switched capacitor filter design system for real-time image processing

    The author presents a new method of switched capacitor (SC) network design for two-dimensional real-time filtering. A model of such a network is presented with a computer design system for 2-D SC filters. This system uses a novel compact matrix description of a 2-D network that is fast and efficient. The problem of 2-D filter design is reduced to the problem of 1-D multiport SC network synthesis. ... View full abstract»

    Multivariate data ordering and its use in color image filtering are presented. Several of the filters presented are extensions of the single-channel filters based on order statistics. The statistical analysis of the marginal order statistics is presented for the p-dimensional case. A family of multichannel filters based on multivariate data ordering, such as the marginal median, the vecto... View full abstract»

    The concept of multidimensional mixed domain transform/spatiotemporal (MixeD) filtering is extended beyond the discrete Fourier transform (DFT) to include other types of discrete sinusoidal transforms, including the discrete Hartley transform (DHT) and the discrete cosine transform (DCT). Two MixeD filter examples are given, one using the two-dimensional (2-D) DHT and the other using the 2-D DCT, ... View full abstract»
