| 20090015791 | SYSTEM AND METHOD FOR GENERATING CORRESPONDENCE MAPPINGS USING INFRARED PATTERNS - A method performed by a display system is provided. The method includes projecting a first infrared pattern from a first projection plane of a first projector into a scene, capturing the first infrared pattern from the scene in a capture plane of at least one image capture device, and determining a first correspondence mapping between the first projector and the image capture device from at least the first infrared pattern in the first projection plane and the first infrared pattern in the capture plane. | 01-15-2009 |
| 20090027504 | System and method for calibrating a camera - A method of calibrating a camera includes capturing a set of dark images at each of a plurality of different exposure settings, thereby generating a plurality of sets of dark images. Each set of dark images is averaged, thereby generating a fixed pattern noise image corresponding to each one of the exposure settings. The method includes determining fixed pattern noise for at least one pixel of the camera based on an exposure setting of the camera and at least one of the fixed pattern noise images. | 01-29-2009 |
| 20090027523 | System and method for determining a gamma curve of a display device - A method of determining a gamma curve of a display device includes identifying a region of interest of a display surface of the display device. A centroid of the region of interest is calculated. A plurality of input levels is applied to the display device to generate a corresponding plurality of displayed images on the display surface. At least one image of each of the displayed images is captured with a camera. A gamma curve of the display device is calculated based on the captured images and the centroid. | 01-29-2009 |
| 20090037946 | Dynamically displaying content to an audience - A method of dynamically displaying content to an audience is disclosed. The method includes displaying content to the audience wherein at least a portion of the audience is proximate a display means, capturing a plurality of responses from the audience, aggregating the plurality of responses and dynamically updating the displayed content based on the aggregated plurality of responses. | 02-05-2009 |
| 20110309999 | MULTI-PROJECTOR SYSTEM AND METHOD - A method for automatic delivery of consistent imagery in a multi-projector system includes the steps of dividing the projectors into a plurality of sub-groups of projectors, each projector oriented to project a sub-frame to a sub-group display location, and adjusting the output of each projector in each sub-group to provide selected target display characteristics across all sub-groups. | 12-22-2011 |
| 20120014594 | METHOD FOR TONE MAPPING AN IMAGE - A method for tone mapping a digital image comprised of a plurality of high bit depth intensity values in linear space is disclosed. First, a plurality of liner intensity values are mapped from the linear space to a non-linear space ( | 01-19-2012 |
| 20120019670 | MULTI-PROJECTOR SYSTEM AND METHOD - A method for reducing view-dependent artifacts in a multi-projector system includes the steps of measuring, from multiple viewpoints, projection characteristics of an image projected by a multi-projector system, estimating view-dependent projection parameters that can reduce view-dependent artifacts, and computing rendering parameters for each projector so as to reduce the view-dependent artifacts. | 01-26-2012 |
| 20120092359 | Extraction Of A Color Palette Model From An Image Of A Document - A system and method are provided for determining a color palette model from an image of a document. Pixel values of the image of the document are clustered to provide image clusters. Color layers of the image are determined, each color layer corresponding to an image cluster. Aspects of the color palette model can be determined using the color layers. Aspects of the color palette model include a foreground-background color pair for a content block in the document and a background-area color of the document. | 04-19-2012 |
