field of computer vision, tracking and motion estimation of 3D objects take on a significant place. Object tracking is the process of identifying an object of interest, finding position of that object, and following the motion of the object. A lot of applications, especially in robotics, transport or in the military domain, require an accurate knowledge of localization and motion of the objects in the scene. Many works were carried out on the subject, from which emerge 3 classes of methods. Feature-based methods aim at extract ....etc

matlab code object tracking using kalman filter

Basic background of Kalman Filter:

The Kalman filter, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, containing noise (random variations) and other inaccuracies, and produces estimates of unknown variables that tend to be more precise than those based on a single measurement alone. More formally, the Kalman filter operates recursively on streams of noisy input data to produce a statistically optimal estimate of the underlyi ....etc

A NEW ITERATIVE SPEECH ENHANCEMENT SCHEME BASED ON KALMAN FILTERING



ABSTRACT

A new iterative speech enhancement scheme that can be seen as an approximation to the Expectation-Maximization (EM) algorithm is proposed. The algorithm employs a Kalman filter that models the excitation source as a spectrally white process with a rapidly time-varying variance, which calls for a high temporal resolution estimation of this variance.

GPS and INS Integration with Kalman Filtering for Direct Georeferencing of Airborne Imagery

1 INTRODUCTION
Georeferencing can be defined as a process of obtaining knowledge about the origin of some event
in space-time. Depending on the sensor type, this origin needs to be defined by a number of
parameters such as time, position (location), attitude (orientation) and possibly also the velocity of
the object of the interest. When this information is attained directly by means of measurements
from sensors on-board the vehicle ....etc

OBJECT TRACKING IN VIDEO SEQUENCES

ABSTRACT

This gives an overview of Object tracking, the problem of estimating the
trajectory of an object in the image plane as it moves around a scene.. In this paper, we divide the tracking methods into three categories based on the use of object representations, namely, methods establishing point correspondence, methods using primitive geometric models, and methods using contour evolution. Note that all these classes require object detection at some point. Rec ....etc

Filtering is desirable in many situations in engineering and embedded systems. For example, radio communication signals are corrupted with noise. A good filtering algorithm can remove the noise from electromagnetic signals while retaining the useful information. Another example is power supply voltages. Uninterruptible power supplies are devices that filter line voltages in order to smooth out undesirable fluctuations that might otherwise shorten the lifespan of electrical devices such as computers and p ....etc

Abstract

It is now quite common in the recursive approaches for motion estimation, to find applications of the Kalman filtering technique both in time and frequency domains. In the block-based approach, very few approaches are available of this technique to refine the estimation of motion vectors resulting from fast algorithms.. This paper proposes an object motion estimation which uses the Kalman filtering technique to improve the motio ....etc

Hello,
Here I want to get help about the image processing. Here I want to inform that I am using a webcam. I want to differentiate between the objects of the same size but having different coloures. The object is the ball of 50mm diameter. It can be of three different coloures- red, blue or black. Please let me know how I can track that ball and estimate, where the ball would be after some certain time or when and where it will reach. The ball is rolled on a ramp.
Thank you.. ....etc
