Abstract

A 3D space-time motion detection based DSA control point selection algorithm is proposed. Main content is to detect the movement of image points based on the control selection and registration algorithm and using DSA image sequences to speed up the registration of control points. The image features, such as the edge, are used as the control points to register image effectively. According to the location of control points, 3D space-time characteristics are used to search control points, and it will further reduce the number of control points, and make the control point registration more accurate.
