Two Linear-Time Algorithms for Computing the Minimum Length Polygon of a Digital Contour
The Minimum Length Polygon (MLP) is an interesting first order approximation of a digital contour. For instance, the convexity of the MLP is characteristic of the digital convexit...

Unequal Length First-Order Linear-Phase Filter Banks for Efficient Image Coding
In this paper, we present the structure and design method for a firstorder linear-phase filter bank (FOLPFB) which has unequal filter lengths in its synthesis bank (UFLPFB). A FOL...

Fast Pseudo-enhancement Correction In Ct Colonography Using Linear Shift-invariant Filters
This paper presents a novel method to approximate shiftvariant Gaussian filtering of an image using a set of shiftinvariant Gaussian filters. This approximation affords filtering ...

Robust fuzzy control of nonlinear systems using shape-adaptive radial basis functions
Recently, various adaptive fuzzy control schemes have been proposed to deal with nonlinear systems whose dynamics are poorly understood by using the parameterized fuzzy approximat...

FIR Filter Approximation by IIR Filters Based on Discrete-Time Vector Fitting
— We present a novel way of approximating FIR filters by IIR structures through generalizing the vector fitting (VF) algorithm, popularly used in continuous-time frequency-doma...
