Title     Research on the Algorithm of Electronic Image Stabilization
Abstract
Image guidance technology in the military has been widely used, Electronic Image Stabilization technology is the key technology of image-guided technology, it is an extension of human vision, the research about image stabilization algorithm have a major role in electronic image stabilization .With the rapid development of VLSI, EIS has got more widely applied and made up for Optical Image Stabilization and Mechanical Image Stabilization shortages effectively. So the algorithm research considered as the foundation of EIS is extraordinary important for the accurate guidance.
In this paper, on the basis of analyzing Image Stabilization Techniques and several common image stabilization modes, the theory and the mathematical model of EIS are studied, as well as main characteristics and steps of EIS. Combined with the particularity of the camera system, image guidance function environment and the target function, several normal algorithms are introduced and EIS system is emulated in MATLAB software environment based on the basic principle of gray projection algorithm and intensive study of several kinds of algorithm, including pre-processing, motion vector estimation, motion vector smoothing and motion vector compensation. The gray projection algorithm adopted in this experiment has been proved to meet the demand of accuracy character. In the end of the paper, the problems appear in experiment are analyzed deeply and further research is suggested.
Keywords Electronic Image Stabilization, gray projection, motion vector estimation, motion vector compensation
