  • Motion compensation of an image sequence using optimal polyline tracking
    Patent number: 6195445
    Abstract: A technique of displaying a segment of a coronary artery in a stabilized cineangiogram. A computer system receives a sequence of images of a conventional cineangiogram. A user displays a first image on a monitor and selects a point on an arterial segment. The computer system invokes an image tracking procedure that employs active optimal polyline contours to locate the arterial segment and a fixed point in each of the image frames of the conventional cineangiogram. The computer system produces a stabilized cineangiogram by translating the images to place the arterial segment in substantially the same viewing location in each one of the image frames.
