Abstract: A method, system, and computer-readable storage medium are disclosed for determining characteristics of light sources. In one embodiment, an image comprising pixels may be received. The image may be affected by a plurality of light sources including a first light source and a second light source. The first light source and the second light source may overlap. The intensity and direction of each of the plurality of light sources in the image may be determined. In one embodiment, the color of each light source may also be determined.

Abstract: A method, system, and computer-readable storage medium are disclosed for generating a three-dimensional (3D) shape based on a two-dimensional (2D) image. In one embodiment, an image comprising a 2D representation of a 3D object is received. Characteristics of one or more light sources affecting the image may be determined. A 3D mesh approximating a shape of the 3D object may be generated based on a first downsampled version of the image. A candidate image may be rendered based on the 3D mesh and the characteristics of the light sources. The 3D mesh may be output if a difference between the image and the candidate image is smaller than a threshold error value.
