IIR filters are digital filters with infinite impulse response. Unlike FIR filters, they have the feedback (a recursive part of a filter) and are known as recursive digital filters. Figure 2 Block diagrams of FIR and IIR filters For this reason IIR filters have much better frequency response than FIR filters of the same order. Unlike FIR .

Extended Kalman Filter (EKF) is often used to deal with nonlinear system identi cation. However, as suggested in [1], the EKF is not e ective in the case of highly nonlinear problems. Instead, two techniques are examined herein, the Unscented Kalman Filter method (UKF), proposed by Julier and

ror (QMF) filters, IIR-QMF filters, Pseudo-QMF filters and nonlinear phase time- reversed QMF filters. Emphasis is given to nonlinear phase time-reversed QMF filters since they can be designed to remove all three types of distortion from the reconstructed signal. These filters are designed using the McClellan-Parks algo- rithm.

domain to obtain a digital filter that meets the specifications. The commonly used analog filters are 1. Butterworth filters - no ripples at all, 2. Chebychev filters - ripples in the passband OR in the stopband, and 3. Elliptical filters - ripples in BOTH the pass and stop bands. The design of these filters are well documented in the literature.

In contrast to IIR filters, FIR filters have a linear phase and inherent stability. This benefit makes FIR filters attr active enough to be designed into a large number of systems. However, for a given frequency response, FIR filters are a higher order than IIR filters, making FIR filters more computationally expensive. Figure 1 1.

Our method applies a one-dimensional Kalman filter to each pixel of the camera array to track the pixel intensity.

CHAPTER TWO BACKGROUND 2.1 IIR Digital Filters The analysis of roundoff noise for IIR filters proceeds in the same way as for FIR filters. The analysis for IIR filters is more complicated because roundoff noise computed internally must be propagated through a transfer function from the point of the quantization to the filter output.

the presence of high non-linearities, Monte Carlo based Kalman Filters usually give satisfac-tory results. The Ensemble Kalman Filter (EnKF) [1, 2] was recently used for damage detec-tion in strongly nonlinear systems [4], where it is combined with non-parametric modeling techniques to tackle structural health monitoring for non-linear systems.

I. INTRODUCTION Nonlinear methods in signal and image processing have become increasingly popular over the past thirty years. There are two general families of nonlinear filters: the homomorphic and polynomial filters, and the order statisticand morphological filters [1]. Homomorphic filters were developed during the 1970's and obey a
