Abstract: Disclosed is a system and method for presenting multiple horizontally offset views, each view comprised of image data. A computer vision tracker device tracks a left and right eye position for a viewer relative to the display to determine a viewpoint for the left and right eye. A pixel modulation module associates two of the multiple views with the left eye position and the right eye position. Image intensity weighting factors are calculated for the two left eye views and the two right eye views. The intensity of each view associated with the left eye position and right eye position are modulated according to the weighting factors determined for the left eye position and the right eye position. The two left eye views and right eye views are blended into respective single views to be perceived by the left eye and right eye when projected on the display.

Abstract: Compensation of ambient illumination. A visible image of an object with ambient illumination is captured. Image brightness of at least a portion of said object of said visible image is sampled. A difference between sampled image brightness of at least said portion of said object and a target brightness profile is determined. The difference is compensated for by projecting additional illumination onto said object.

Abstract: Methods and apparatus to direct attention in a video content display are disclosed. An example method to direct attention in a video content display, includes determining a location in a display interface to which attention is to be directed based on video content to be displayed, and modulating with a stimulus, at a frequency such that the stimulus is detectable by human peripheral vision and is less detectable by human foveal vision, a portion of the video content displayed in the location with a stimulus to direct attention to the location.

Abstract: Various embodiments of the present invention are directed to object segmentation of digital video streams and digital images. In one aspect, a method for segmenting an object in a digitally-encoded image includes designing a non-linear local function that generates function values associated with identifying the object of interest and a combination function that combines the function values, the object of interest encoded in digital image data. The method includes forming orthogonal projections of the digital image data based on the function values and the combination function. In addition, the orthogonal projections can be used to determining boundaries segmenting the object in the digital image data. The method also includes extracting an image of the object that lies within the boundaries.

Abstract: Certain examples of the present invention are directed to an image-recording device. The image-recording device includes an imaging component that records an image of an environment, a projection component that projects, into the environment, an (n,d) reliable M*-sequence of symbols, and a distance component. The distance component identifies j consecutive symbols reflected back to the imaging component from a surface in the environment, where j?n, detects and corrects a misidentified symbol within the j consecutive symbols based on the minimum distance t of the (n,d) reliable M*-sequence, determines a first position of the j consecutive symbols with respect to the image, determines a second position of the j consecutive symbols in the M*-sequence of symbols, and determines, from the first and second position, a distance t from the surface to the imaging component.

Abstract: Images of a document having a surface are captured. In this process, multiple scan lines respectively illuminated from different illumination angles relative to the document surface are scanned across the document surface in a first scan direction in relation to orientation of the document. Multiple scan lines respectively illuminated from different illumination angles relative to the document surface are scanned across the document surface in a second scan direction in relation to orientation of the document. The captured images are generated from scan line illumination reflected from the document surface during the scanning of respective ones of the scan lines across the document surface. A crease or a tear is detected in the document based on the captured images.

Abstract: Embodiments of the present invention relate to reflective surfaces. In one embodiment, a reflective surface comprises a substrate and multiple light-reflecting features disposed on the substrate. One or more images reflected from the multiple features can be produced by selectively covering at least portions of select features with a light absorbing material. Each image can be separately viewed by varying an observer's point of observation or each image can be viewed from a fixed observation point by varying the direction incident light impinges the surface.
