  • Systems and methods for tracking facial features
    Patent number: 10685213
    Abstract: A computing device determines, in a first frame, a first location of a feature point and also determines in a second frame, a second location of the feature point. The computing device generates a motion vector for the feature point in the first frame and relocates the first location in the first frame to a first refined location based on the motion vector. The computing device generates a smoothed location of the feature point in the second frame based on the refined location and the second location of the feature point in the second frame.

  • GENERATING EFFECTS IN A WEBCAM APPLICATION
    Publication number: 20090257623
    Abstract: A system and a method for generating effects in a webcam application are provided. The method includes identifying a first object and a second object in a video image. The method also includes adding a first user-created object to the video image to create an altered video image and adding a second user-created object to the altered video image to further alter the altered video image. Other steps included are associating the second user-created object with the second object; identifying a movement of the second object; and moving the second user-created object in the altered video image in accordance with the association of the second user-created object with the second object. The first object is a static object, and the first user-created object is manually movable. The movement of the second user-created object in association with the second object is independent of a movement of the first user-created object.
