20120294543 | SYSTEM AND METHODS OF COMPRESSED SENSING AS APPLIED TO COMPUTER GRAPHICS AND COMPUTER IMAGING - Compressed sensing can be mapped to a more general set of problems in computer graphics and computer imaging. Representation of a rendered scene in the formulation y=Âx produces higher-quality rendering with less samples than previous approaches. A filter formulation Φ makes point samples compatible with wavelet and therefore allows reconstruction of 2-D images from a set of measured pixels (point samples). | 11-22-2012 |
20140029849 | SYSTEM AND METHODS FOR RANDOM PARAMETER FILTERING - The invention produces a higher quality image from a rendering system based on a relationship between the output of a rendering system and the parameters used to compute them. Specifically, noise is removed in rendering by estimating the functional dependency between sample features and the random inputs to the system. Mutual information is applied to a local neighborhood of samples in each part of the image. This dependency is then used to reduce the importance of certain scene features in a cross-bilateral filter, which preserves scene detail. The results produced by the invention are computed in a few minutes thereby making it reasonably robust for use in production environments. | 01-30-2014 |

20140376807 | Patch-Based Synthesis Techniques Using Color and Color Gradient Voting - Methods, apparatus, and computer-readable storage media for patch-based image synthesis using color and color gradient voting. A patch matching technique provides an extended patch search space that encompasses geometric and photometric transformations, as well as color and color gradient domain features. The photometric transformations may include gain and bias. The patch-based image synthesis techniques may also integrate image color and color gradients into the patch representation and replace conventional color averaging with a technique that performs voting for colors and color gradients and then solves a screened Poisson equation based on values for colors and color gradients when blending patch(es) with a target image. | 12-25-2014 |

20080242254 | RX DUAL-BAND MIXER - A dual-band input transceiver block is formed to operably receive one of a 2.4 GHz radio frequency signal or a 5.0 GHz radio frequency transceiver signal in a manner that minimizes duplication of circuitry and creates a combined circuit path for RF front end input stages for much of the input stage. More specifically, the embodiments of the present invention include separate amplification and mixing stages whose outputs are combined by a stabilized load with circuitry for removing a common mode feedback signal. As such, downstream components, such as amplifiers, filters, analog-to-digital converters, and other input path circuit elements, are not duplicated and may be used regardless of whether the dual-band transceiver is operating in a first or second frequency band. Operation is, in the described embodiment, only one frequency input at a time though the invention is not limited to such operation. More specifically, a first input section is operably coupled to receive a first local oscillation input and a first frequency band signal input. A second input section is coupled to receive a second local oscillation input and a second frequency band signal input. Outputs of the first and second input sections are produced to a stabilized load with a common mode feedback block for removing a common mode feedback signal. As such, an output signal is produced having a regulated DC level and having any common mode feedback signal eliminated there from. | 10-02-2008 |
