Abstract: A two-dimensional (2D) image and a three-dimensional (3D) of an environment may be captured. Upon identifying a location and/or contour of an object from the 3D image, the object from the 3D image may be mapped onto the 2D image. The object, including its location and contour, may be identified from the 2D image. Based at least partly on a comparison between the object from the 3D image and the object from the 2D image, a disparity may be calculated. The location and contour of the object may be determined when it is determined that the disparity is less than or equal to a predetermined threshold. Otherwise, the object from the 3D image may be remapped onto the 2D image.

Abstract: Techniques are described for performing automatic focusing of a projected image on a mobile projection surface. Specific regions of the projected image are identified that are likely to be desired to stay in optimal focus, and attributes of those specific regions, such as sharpness and contrast, can be used to determine the need to refocus the image. Advanced knowledge of the image data being projected can be utilized to determine the specific regions of the projected image that require monitoring for optimal focusing.
