摘      要：Digital image stabilization technique plays important roles in video surveillance and object *** useful electronic image stabilization algorithms have been studied.A real-time algorithm is proposed based on field image gray projection which enables the regional odd and even field image to be projected into x and y directions and thus to get the regional gray projection curves in x and y directions,*** the odd field image channel,motion parameters can be estimated via iterative minimum absolute difference based on two successive field image regional gray projection *** motion compensations can be obtained after using the Kalman filter ***,the odd field image is adjusted according to the *** the mean time,motion compensation is applied to the even field image channel with the odd field image gray projection curves of the current *** minimizing absolute difference between odd and even field image gray projection curves of the current frame,the inter-field motion parameters can be ***,the even field image can be adjusted by combining the inter-field motion parameters and the odd field ***,the stabilized image sequence can be obtained by synthesizing the adjusted odd and even field *** results show that the proposed algorithm can run in real-time and have a good stabilization *** addition,image blurring can be improved.
