Fast Digital Image Stabilization Algorithm Based on Gray Projection

In aircraft,tanks or other movement imaging platform,the camera will be dithering and get instable image sequences because of the interference by the airflow or the rough road.It will directly affect the follow-up image processing.A fast digital image stabilization algorithm based on gray projection is proposed in this paper:firstly,the image is projected into one-dimensional curves;then calculating movement vector by one-dimensional correlation.Because the algorithm processes gray information directly and could restrain the noises,it can acquire high accurate image stabilization.And it is fast because of smaller amount of computation.The algorithm has been implemented on FPGA and shows good performance.
