  • Recovering 3D structure using blur and parallax
    Patent number: 8718357
    Abstract: A system and method for generating a focused image of an object is provided. The method comprises obtaining a plurality of images of an object, estimating an initial depth profile of the object, estimating a parallax parameter and a blur parameter for each pixel in the plurality of images and generating a focused image and a corrected depth profile of the object using a posterior energy function. The posterior energy function is based on the estimated parallax parameter and the blur parameter of each pixel in the plurality of images.
    Type: Grant
