  • Patent number: 9161010
    Abstract: A system and method for generating robust depth maps includes a depth estimator that creates a depth map pyramid structure that includes a plurality of depth map levels that each have different resolution characteristics. In one embodiment, the depth map levels include a fine-scale depth map, a medium-scale depth map, and a coarse scale depth map. The depth estimator evaluates depth values from the fine-scale depth map by utilizing fine-scale confidence features, and evaluates depth values from the medium-scale depth map and the coarse-scale depth map by utilizing coarse-scale confidence features. The depth estimator then fuses optimal depth values from the different depth map levels into an optimal depth map.

  • Patent number: 8284260
    Abstract: Improving color calibration, and similar operations, by generating an optimal raw RGB color chart, in the raw RGB domain, for an imaging device with a given type of image sensor, such as for a digital still camera. Calibration is performed in response to a constraint which takes into account the spectral sensitivity of the image sensor used on the camera as well as spectral reflectance and spectral radiance of multiple illuminants. Calibration is performed using the raw RGB color chart which is illuminant independent and image sensor specific and which can match the calibration performance of known calibration standards, such as Macbeth 24.
