摘要： A surface measurement module for 3-D image acquisition of a subject-under-inspection. The module having: (a) a casing to house a pattern shifting device having a fixed-pattern optic through which light from a light source is passed, an output of the pattern shifting device being directed at a polarizing beam splitter and the polarized output of the splitter directed through a lens assembly comprising at least one lens element; (b) a reflector to direct the polarized output exiting the lens assembly, to illuminate a surface of the subject-under-inspection; (c) a scattered light illumination off the surface is directed back through the lens assembly for capture by an image sensor; and (d) the casing also housing the polarizing beam splitter, the lens assembly, and the image sensor. The output of the fixed-pattern optic comprises a multi-frequency pattern. The pattern shifting device may be a linear or rotating type.

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： A method and system for using one or more sensors configured to capture two-dimensional and/or three dimensional image data of one or more objects. In particular, the method and system combine one or more digital sensors with visible and near infrared illumination to capture visible and non-visible range spectral image data for one or more objects. The captured spectral image data can be used to separate and identify the one or more objects. Additionally, the three-dimensional image data can be used to determine a volume for each of the one or more objects. The identification and volumetric data for one or more objects can be used individually or in combination to obtain characteristics about the objects. The method and system provide the user with the ability to capture images of one or more objects and obtain related characteristics or information about each of the one or more objects.

摘要： An automated lenticular photographic system includes an interface that permits a user to upload image files and image processing and printing equipment that is in communication with the interface for receiving the uploaded image files and processing the uploaded image files to create an interlaced print image file that is used to produce an interlaced print sheet containing interlaced print images. A pair of registration marks is formed on the interlaced print sheet outside of borders of the interlaced print images. The system also includes a processing station where the interlaced print sheet is aligned with a lenticular lens sheet with a registration system that detects whether the lenticular lens sheet is off-centered and skewed relative to the interlaced print sheet. The system also includes means for controllably adjusting the position of the lenticular lens sheet relative to the interlaced print sheet until proper registration between the lenticular lens sheet and the interlaced print sheet is achieved. The lenticular lens sheet is at least selectively joined to the interlaced print sheet to provide a lenticular product that can be delivered back to the user.

摘要： An image may be quantized into a pattern of dots, e.g., for devices capable of printing dots of variable size and variable color intensity. One may use a pre-determined mapping of the continuous-tone intensity value into a discrete vector of intensity values, and each intensity value may then be processed by a set of binary quantizers. The resulting binary vector may then be mapped into a combination of available dot sizes and color intensities. Through a scalar multiplier, the pre-determined mapping of continuous-tone intensity values may be used as multiple print resolutions.
