Abstract

In this paper, the common principles of digital image processing are investigated. By using these principles, one can deploy simple devices such as a PC or webcam to establish a system based on Image processing techniques in order to test different algorithms. The use of color software filters increases the need for processing power of image processor, but based on the ease of a capability and inexpensiveness of modern computers can reduce the total system expenses. Further in this research, several image processing systems in which cameras are used as feedback sensor in close loop control systems. These cameras can aid in obtaining kinematic parameters such as speed and position. In some cases the use of this method, due to its system physical status can be the best method. In some other situation this method could be used alongside of other choices. The chief advantage of this technique is that the instrumentation tools can not affect the case under study.
