By storing an object's data in a dictionary, you can easily create a Filter class which tests a given object against a set of nested inclusion rules. This works particularly well for database filtering. Platforms: Windows, Mac, *nix, Python, BSD Solaris

It will compute the Kalman gain and the stationary covariance matrix using a Kalman filter with a linear forward looking model. Requirements: - MATLAB 7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

Easy Filter Applet is a generic filter that allows people like students, scientists, engineers, ... in "image processing" to show their work in a web interface. It's not a static GUI !! -Users can interact with filter's parameters in real time !!The Applet is easy to set up. It allows as many... Platforms: Java

It will allow the webmaster to control the rewrite of URLs before the page is loaded.UrlRewriteFilter uses an xml file for configuration. Most parameters can be Perl5 style Regular Expressions or Wildcard Expressions.Here are some key features of "Url Rewrite Filter":dlTE URL Tidyness / URL... Platforms: Java

This script adds to any html table a "filter by column" feature that enables users to filter and limit the data displayed within a long table. It even works on tables with uneven rows.The script automatically adds a filter grid bar at the top of the desired table. Users can use the following... Platforms: JavaScript

This script removes the dollar sign ($) and commas (,) from a a text box. It is useful if you require input of only numbers. You may also modify the script to filter out whatever characters you want. Platforms: JavaScript

This package contrasts and compares the response of SAW correlators to user-specified BPSK codes based upon finger number, carrier frequency, temperature differences, frequency shifts, and substrate. Also included is a SAW filter design module and basic multistrip coupler design module. Platforms: Matlab

Shows graphically the various stages of discrete convolution for any two 1-D signals.This is for educational purposes really so the screens are optimized for signals of a few samples. Between two stages the figure pauses and requires the user to strike a key to continue. This should allow... Platforms: Matlab

This function returns coefficients of Gaussian lowpass filter.Advantages of Gaussian filter: no ringing or overshoot in time domain.Diasadvantage: slow rolloff in frequency domain.Pass SR=sampling rate, fco=cutoff freq, both in Hz, to the function.Coefficients for FIR filter of length L (L always... Platforms: Matlab

Recently needed to see the effects of a CIC decimating filter but realized that with my new license of Matlab, I did not have access to the Filter Design Toolbox. This is a quick attempt at a simulation to re-create the effects of CIC-decimation but without the fixed-point access to the... Platforms: Matlab

This is a simple demo of a Kalman filter for a sinus wave, it is very commented and is a good approach to start when learning the capabilities of it. Platforms: Matlab

Derives the transfer function for digital implementation of a first order RC low pass filter and plots the step and frequency response.For details, refer to the post:http://www.dsplog.com/2007/12/02/digital-i...ow-pass-filter/ Platforms: Matlab

In this implementation of tracking a ball, we will track a live ball using Kalman filter. The tracking will switch to autorun mode when the sight of the ball is lost and Kalman will estimate the motion based on it's previous statesThere are two models. One model is a simple simulation of the... Platforms: Matlab

The purpose of this tutorial is to illustrate the usage of Kalman Filter by a simple example.The problem: Predict the position and velocity of a moving train 2 seconds ahead, having noisy measurements of its positions along the previous 10 seconds (10 samples a second).Ground truth: The train is...
