Image Processing Based Tracking System
[attachment=17751]
Introduction
Image processing has several applications in astronomy, medical science, military, and other fields of technology and science.
An application of image processing include the need for measuring kinematic parameters of moving robot in which by determining the robot joints and its images, these parameters are measured [1].
Another application was the puzzle solver robot in which image processing is used to recognize the pattern by image processing based closed loop control [2].
2 Image Matrixes
Image capture sensor is formed from some light sensitive elements. The voltage of each element is proportional to the intensity of radiation light.
The image forms on the sensor plane by variating light propagation tools such as convergent lenses (Figure2).

Color separation filters and noise effect reduction
Separating a particular color or color node is common need in various color image processing systems. In most cases in order to separate and pass a particular color colored filters are used.
A less expensive and more flexible solution is the utilization of software filters specially when using webcam as image capturing sensor.
Different digital image saving methods are developed among them, RGB color space have more application in color image processing.
Tracking a moving target and laser designation
Tracking moving objects over time is a complex problem in computer vision and has been an important research subject over the last few years [4], [5], [6]. Impressive tracking systems have been developed for some specific applications [7], [8].
In case of selecting one object among several, the subject becomes more complex, especially if the targets are of nearly same color.
In this case, system can track the target more accurately by limiting the search window while zoomed around the target.
