    摘要： A method for preparing an article of lenticular imaging. The method comprises receiving a plurality of source images, superimposing at least one deghosting element on the plurality of source images, the deghosting element being formed to reduce an estimated ghosting artifact from the article, interlacing the plurality of processed source images so as to form a spatially multiplexed image, and preparing the article by attaching an optical element to the spatially multiplexed image.

    摘要： A system and method for determining the track of a projectile use a thermal signature of the projectile. Sequential infrared image frames are acquired from a sensor at a given position. A set of frames containing spots with characteristics consistent with a projectile in flight are identified. A possible projectile track solution for said spots is identified. A thermal signature value for each pixel of each spot of the possible solution is determined. The determined thermal signature is then compared to an actual thermal signature for a substantially similar projectile track to ascertain whether the determined thermal signature substantially matches the actual thermal signature, which indicates that the possible projectile track solution is the correct solution.

    摘要： A technique, associated system and program code, for retrieving depth information about at least one surface of an object, such as an anatomical feature. Core features include: projecting a composite image comprising a plurality of modulated structured light patterns, at the anatomical feature; capturing an image reflected from the surface; and recovering pattern information from the reflected image, for each of the modulated structured light patterns. Pattern information is preferably recovered for each modulated structured light pattern used to create the composite, by performing a demodulation of the reflected image. Reconstruction of the surface can be accomplished by using depth information from the recovered patterns to produce a depth map/mapping thereof. Each signal waveform used for the modulation of a respective structured light pattern, is distinct from each of the other signal waveforms used for the modulation of other structured light patterns of a composite image; these signal waveforms may be selected from suitable types in any combination of distinct signal waveforms, provided the waveforms used are uncorrelated with respect to each other. The depth map/mapping to be utilized in a host of applications, for example: displaying a 3-D view of the object; virtual reality user-interaction interface with a computerized device; face—or other animal feature or inanimate object—recognition and comparison techniques for security or identification purposes; and 3-D video teleconferencing/telecollaboration.

    摘要： The present invention embodies a technique, referred to as Secure QR Codes, which not only provides aesthetically enhanced QR codes but also allows for security. It can embed a standard black and white QR code, referred to as a public QR code, and a secret QR code, both into a secure QR code. The secure QR code produced is composed of colored cells. The public black and white QR code must first be, either aesthetically enhanced into an enhanced colored QR code, or transformed into a colored QR code with cells of uniform color obtained by transforming each of the black and white cells of the public QR code into cells that takes a color from a subset of possible colors, such that the luminance of each colored cell approximates accurately the black or white luminance values of the public QR code.

    摘要： Spectral imaging sensors and methods are disclosed. One spectral imaging sensor includes a light source, an array of coded apertures, one or more optical elements, and a photodetector. The light source is configured to emit a plurality of pulses of light toward an object to be imaged. The array of coded apertures is positioned to spatially modulate light received from the object to be imaged. The optical elements are configured to redirect light from the array of coded apertures. The photodetector is positioned to receive light from the one or more optical elements. The photodetector comprise a plurality of light sensing elements. The plurality of light sensing elements are operable to sense the light from the one or more optical elements in a plurality of time periods. The plurality of time periods have a same frequency as the plurality of pulses of light.
