Systems and methods for registering arbitrary visual features for use as fiducial elements are disclosed. An example method includes aligning a geometric reference object and a visual feature and capturing an image of the reference object and feature. The method also includes identifying, in the image of the object and the visual feature, a set of at least four non-colinear feature points in the visual feature. The method also includes deriving, from the image, a coordinate system using the geometric object. The method also comprises providing a set of measures to each of the points in the set of at least four non-colinear feature points using the coordinate system. The measures can then be saved in a memory to represent the registered visual feature and serve as the basis for using the registered visual feature as a fiducial element.

The present invention is a mixed-reality system including a server and a portable terminal device, the portable terminal device having a display for displaying a virtual object to a user present in a predetermined real space and having a photographing device that photographs the real space, the mixed-reality system serving to display, on the display, a mixed-reality image in which the virtual object is superimposed on a photographed image of the real space, wherein, at each of one or more predefined positions on a real object present in the predetermined space, an MR marker constituted of an identification code containing position information corresponding to that position and an alignment marker having a polygonal shape is disposed. The server includes a virtual-space-data storage unit and an application storage unit, and the portable terminal device includes a browser unit, a marker recognition unit, a position determination unit, and an image generation unit.

The present invention relates to a method and apparatus to determine the position of an image sensor relative to a predetermined continuous pattern of colors and/or objects based on the images said patterns of colors and/or objects produces within the image sensor.

Techniques for generating and processing two-dimensional barcodes are described. One example method includes identifying original content to be encoded in a two-dimensional (2D) barcode structure; and generating a 2D barcode associated with the original content based on at least the 2D barcode structure and the original content, wherein the 2D barcode structure includes at least an identification field and a data field, and the identification field indicates one or more data elements in the data field.

A graphical indicator comprising a plurality of first header blocks, a plurality of second header blocks and a plurality of data blocks for forming an indicator matrix is provided. Each of the first and second header blocks has a header graphical micro-unit, and each of the data blocks has a data graphical micro-unit. An array area is formed by the second header blocks and the data blocks. A first virtual line and a second virtual line are respectively formed by virtual centers of the first and second header blocks, and an included angle between the first and second virtual lines is less than 90 degrees.

A method and system for searching databases of fashion and style using query catching metadata, API's, SKU numbers, CPS tracking and data feeds to filter by search terms, text keywords, numeric values, visual recognition, real-time inventory data and geographic location filtered by the user. The method and system simplifies and improves the user experience by allowing full customization of the above queries to return results based upon turn relationships, editorial assertions, visual recognition, SKU matching and barcoding. The method and system uses an underlying search engine that enhances search results by populating inventory through SKU numbers, numeric values as well as aggregates relative style content and displays links on the results page of retailers, designer brands, style content providers, geographic locations to enhance automatic indexing and identifying store locations having searched for items in its inventory based on its real-time inventory data.

A device for identifying an aluminum alloy die-cast hub includes a laser scanning means, a controller and a computer, in which the laser scanning means includes an image sensor and is configured to shoot an image from the surface of the aluminum alloy die-cast hub; the controller and the computer are in data connection with the image sensor, and the model information of the hub is read from bar code information.

Techniques for generating and processing two-dimensional barcodes are described. One example method includes identifying original content to be encoded in a two-dimensional (2D) barcode structure; and generating a 2D barcode associated with the original content based on at least the 2D barcode structure and the original content, wherein the 2D barcode structure includes at least an identification field and a data field, and the identification field indicates one or more data elements in the data field.

In general, the subject matter described in this specification relates to security credentials for documents, such as identification documents. One example is an identification document that includes a photographic image of an individual associated with the document, and a spiral pattern applied to a region of the identification document. The spiral pattern includes an elliptical spiral segmented into a plurality of arc segments, where wherein the arc segments of the spiral pattern encode identification data associated with the individual. Other implementations include corresponding processes, systems, apparatus, and computer programs related to generating and verifying identification documents with spiral patterns.
