  • Single image photometric stereo for colored objects
    Patent number: 9396544
    Abstract: Techniques are disclosed for reconstructing the surface geometry of an object using a single image. A computing device is configured to reconstruct a surface for a colored object from a single image using surface integrability as an additional constraint. The image is captured under an illumination of three fixed colored lights that correspond to three color channels, such as red, green and blue (RGB). The RGB image can be separated into three grayscale images, with different lighting for each image, and the geometry can be reconstructed by computing the surface normals of these separate images. Depth can be estimated by integrating the surface normals.

  • GENERATING A COMPOSITE IMAGE FROM VIDEO FRAMES
    Publication number: 20140293074
    Abstract: A method described herein includes acts of receiving a sequence of images of a scene and receiving an indication of a reference image in the sequence of images. The method further includes an act of automatically assigning one or more weights independently to each pixel in each image in the sequence of images of the scene. Additionally, the method includes an act of automatically generating a composite image based at least in part upon the one or more weights assigned to each pixel in each image in the sequence of images of the scene.
