Symbols are described that contain detection patterns that facilitate the determination of location, alignment, size and orientation of the symbol in an image. Detection patterns are described that possess geometric shapes susceptible to efficient decoding using probabilistic ... 06/07/07 - 20070125862 - Two-dimensional code, and method and apparatus for detecting two-dimensional code A two-dimensional code includes a polygonal exterior region distinguishable from a background on the basis of brightness or color and an interior region disposed at a predetermined distance from the perimeter of the exterior region. The interior region is divided into cells of a predetermined size so that information is ... 03/29/07 - 20070069026 - Two-dimensional code detector and program thereof, and robot control information generator and robot A two-dimensional code detector detecting a two-dimensional code including a plurality of position identifying patterns and an information pattern and generating control information for an object provided with the two-dimensional code, the two-dimensional code detector includes: an image input unit which inputs an acquired image obtained by an image pickup ... 12/28/06 - 20060289652 - Binary code symbol for non-linear strain measurement and apparatus and method for analyzing and measuring strain therewith A binary code symbol for non-linear strain measurement designed specifically for perimeter-based deformation and strain analysis. The symbol is rectangular with a continuous outer perimeter, two data regions along adjacent sides of the rectangle and a utility region adjacent each side opposite the data regions. Each data region is made ... 08/10/06 - 20060175414 - Method for reading out symbol information and device for reading out symbol information To provide a method for reading out symbol information and a device for reading out symbol information which are able to prevent a decline in decoding reliability by reducing noise caused by a quantized error, localized contaminations or the like. The method for reading out symbol information may comprise a ... 04/06/06 - 20060071080 - Information processing method Analyzing copyright information written in a predetermined position of an optically read two-dimensional code symbol (step S41). After that, performing analysis in accordance with the data type, e.g., URL non-display data (UND), text data (TXD), binary data (BND), sound data (MSD), or image data (IMD), of content data in the ... 12/01/05 - 20050263598 - Display apparatus, light receiving apparatus, communication system, and communication method A communication method performed between a display apparatus having a display screen capable of displaying moving pictures and a light receiving apparatus having a light receiving means capable of receiving light by using a two-dimensional dynamic code which is a two-dimensional code changing along the time axis, includes the steps ... 11/03/05 - 20050242186 - 2d rectangular code symbol scanning device and 2d rectangular code symbol scanning method A two-dimensional rectangular code symbol scanning device inputs two-dimensional image data containing two-dimensional rectangular code symbol data and detects code data corresponding to the two-dimensional rectangular code symbol data. The device has a projective transformation calculator for correcting distortion of the two-dimensional rectangular code symbol data by performing projective transformation ... 06/09/05 - 20050121520 - Code type determining method and code boundary detecting method A code type determining method comprises a block selecting step of selecting input image data in units of rectangular blocks, a block determining step of determining whether or not the selected block satisfies a predetermined condition, and a code determining step of determining a type of code included in the ... ### FreshPatents.com Support |
