Single-clock-cycle two-dimensional median filter

Single-clock-cycle two-dimensional median filter - Electronics Letters

p$ise or time delay used in common filter design. RCF fdters are mandatory for reducing IS1 in digital communication systems. The development of a novel active filter is presented in this Letter. The new filter, called the medium filter (MF), includes only two common operational amplifier stages as shown in Fig. 3. The MF provides significantly better IS1 performances than twoor even four’ orde...

A Two Dimensional Median Filter Design Using Low Power Filter Architecture

This brief presents a power architecture for the design of two dimensional median filter .Receiving an input sample and generating a median output at each machine cycle. Sorting method used. The power consumption is reduced by decreasing the number of signal transitions in the circuit. This can be done by keeping the stored samples immobile in the window through the use of token ring in our arc...

Image Restoration with Two-Dimensional Adaptive Filter Algorithms

Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
