Color adaptive watermarking
InactiveUS6590996B1Effectively create and manipulateReduce the amount requiredPicture reproducers using cathode ray tubesPicture reproducers with optical-mechanical scanningColor mappingComputer graphics (images)
A color mapping process enhances a watermark by computing a change in colors that is less visible for a given watermark strength. The mapping process provides smooth transitions from one color region to another, and may be implemented efficiently with a 3D look up table. A user interface scheme enables the user to control encoding of the watermark in desired color regions.

Reflective optical stack for privacy display
ActiveUS20190250458A1High image fidelityIncreasing the thicknessMechanical apparatusAntiglare equipmentVisibilitySpatial light modulator
A privacy display comprises a polarised output spatial light modulator, reflective polariser, plural polar control retarders and a polariser. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. Further, display reflectivity is reduced for on-axis reflections of ambient light, while reflectivity is increased for off-axis light. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction and increased frontal reflectivity to ambient light. In a public mode of operation, the liquid crystal retardance is adjusted so that off-axis luminance and reflectivity are unmodified.

Dimple patterns for golf balls
ActiveUS20100113187A1Improves aerodynamic symmetryMinimize visibilityGolf ballsSolid ballsVisibilityEngineering
The present invention provides a method for arranging dimples on a golf ball surface that significantly improves aerodynamic symmetry and minimizes parting line visibility by arranging the dimples in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while eliminating great circles due to parting lines.

Light module, illumination system and method incorporating data in light emitted
ActiveUS20110044701A1Minimize visibilityMaximize detectabilityElectric light circuit arrangementClose-range type systemsUltimate tensile strengthVisual perception
Proposed is a light module (110) comprising at least two primary light sources (111,112,113) capable of emitting a primary color light. This allows the light module to emit light having intensity (Y) and color coordinates (x,y) through additive color mixing of the constituent primary colors. The light module further comprises an modulator (115) capable of modulating the primary light sources enabling embedment of data in the light emitted. The modulator (115) is arranged to modulate the color coordinates of the light emitted for embedding the data. This is especially advantageous as the sensitivity of the human eye to changes in color is lower than to changes in intensity. The invention thus advantageously allows embedding the data into the light emitted from the light modules (110) of an illumination system (100) without reducing the performance of its primary function as an aid to human vision.

Adjustment Of Perceived Roundness In Stereoscopic Image Of A Head
ActiveUS20160219258A1Maintain disparityMaintain directionTwo-way working systemsSteroscopic systemsParallaxDisplay device
In telecommunication video calling and videoconferencing systems, it is strongly desirable for remote observers to interact with natural gaze cues. In natural gaze interaction, the camera for a source observer appears to be co-located in the eye region of a destination observer image and vice versa. The appearance of camera co-location is achieved for stereoscopic camera pair that are placed either side of an autostereoscopic 3D display. Such cameras typically provide stereoscopic images that have disparity distributions that provide unnatural perceived head roundness. The present embodiments achieve perceived head roundness that is closer to that expected in natural face to face interaction by modification of perceived local depth in detected regions of the head.

A fast, low-memory-requiring, adaptive algorithm for determining and correcting for page background color generally involves quantizing the color component values of the pixels of the scanned page, dividing the scanned color space into a set of bins, and assigning each color in the scanned representation to a particular one of the bins to obtain a summary of the distribution of colors. Statistical information that is indicative color component characteristics of colors in a particular bin is collected for each bin. Using this information, each bin that constitutes a color peak is identified, and a region of influence for each color peak with respect to bins that are not color peaks is determined. The color peak corresponding to the background color of the document is then determined, according to predetermined rules that take into consideration the statistical information and region of influence determination. Three 1-D look-up tables are then constructed to adjust scanned colors.

What is disclosed is a novel system and method for minimizing dot visibility in color marking devices capable of dot-on-dot printing. The present method achieves minimum dot visibility for a given dispersed-dot screen by performing a CMYK to CMYKRGB conversion which uses less visible dots as much as possible before more visible dots are introduced. The output color dot coverages are calculated sequentially to minimize the coverage of more visible dots in a decreasing order of brightness. Resulting images have noticeably reduced halftone graininess, particularly in the mid to darker tone areas. The present method is also computationally efficient.
