07 image filtering of colored noise based on kalman filterstudymate

This document summarizes a research paper on using a Kalman filter to improve the accuracy of vehicle tracking based on GPS data. It describes how the Kalman filter works as a linear recursive technique to estimate the true state of a dynamic system by reducing noise. The document outlines the mathematical model of the Kalman filter and how it is applied to predict and correct vehicle position over time. It also discusses tuning the Kalman filter parameters like process noise covariance Q and measurement noise covariance R. Evaluation of GPS data collected from vehicle tests shows the Kalman filter reduces errors in latitude, longitude and altitude compared to not using the filter.
