    Abstract: Systems and methods are disclosed for removing details from three dimensional (3D) objects, such as cavities and holes. Complexity reduction via hole filling reduces storage, transfer, and rendering costs without adversely impacting quality and is implemented in an automated manner. In some examples, a 3D object is dilated and eroded, and undesirable webbing is removed to preserve a higher percentage of exterior detail. Holes and cavities, which are obscured in many viewing angles, are filled in (e.g., removed), thereby reducing the burden of storing and processing hidden interior surfaces. Various approaches, leveraging distance fields, may be combined for improved benefit.

  • Patent number: 10667887
    Abstract: Tools are described for preparing digital dental models for use in dental restoration production processes, along with associated systems and methods. Dental modeling is improved by supplementing views of three-dimensional models with still images of the modeled subject matter. Video data acquired during a scan of the model provides a source of still images that can be displayed alongside a rendered three-dimensional model, and the two views (model and still image) may be synchronized to provide a common perspective of the model's subject matter. This approach provides useful visual information for disambiguating surface features of the model during processing steps such as marking a margin of a prepared tooth surface for a restoration. Interactive modeling tools may be similarly enhanced.

  • Patent number: 10453187
    Abstract: A method of suppressing background clutter in video imagery of a scene including a foreground target and background clutter includes applying successive images of the video imagery to a clutter suppression process, thereby producing video imagery of a derived scene in which the background clutter is suppressed. This process includes processing the current image to remove a fixed pattern noise associated with the camera, and spatially re-registering the current image to a fixed geolocation or known clutter pattern of the scene in a reference image of the successive images. The process also includes subjecting independent copies of the current image to two infinite impulse response filters having different time constants to produce filtered, time-delayed images, and differencing the filtered images to reduce the background clutter, thereby producing a clutter-suppressed version of the current image in which the background clutter is suppressed with respect to the foreground target.
