ABSTRACT:
A dental imaging system that extracts still images from a digital movie of a patient's mouth. The system allows still images free of shakes or flutter to be taken using an intraoral camera at the desired angle more easily than using conventional still image capture systems which may require several retakes before realizing a flutter-free image at the correct angle. Another embodiment uses image processing techniques, including color filtering and edge detection, to automatically and rapidly detect teeth in an image of a patient's mouth, without having to manually define the outline of each tooth.
