Patent number: 8366004Abstract: This disclosure describes techniques for detecting a barcode within an image. An image processor may, for example, process an image to detect regions within the image that may be barcodes. The image processor may identify regions of the image that exhibit a high concentration of edges and a high concentration of pixels with low optical intensity co-instantaneously as potential barcodes. The image processor may identify the regions using a number of morphological operations. The image processor may then determine whether the identified regions are actually barcodes by verifying whether the region have unique barcode features. The barcode detection techniques described in this disclosure may be independent of barcode size, location and orientation within the image. Moreover, the use of morphological operations results in faster and more computationally efficient barcode detection, as well as lower computational complexity.Type: GrantFiled: February 22, 2008Date of Patent: February 5, 2013Assignee: QUALCOMM IncorporatedInventors: Hsiang-Tsun Li, Jingqiang Li, Hau Hwang, Xiaoyun Jiang, Joseph Cheung

Patent number: 8322620Abstract: A method is provided for reading distorted optical symbols using known locating and decoding methods, without requiring a separate and elaborate camera calibration procedure, without excessive computational complexity, and without compromised burst noise handling. The invention exploits a distortion-tolerant method for locating and decoding 2D code symbols to provide a correspondence between a set of points in an acquired image and a set of points in the symbol. A coordinate transformation is then constructed using the correspondence, and run-time images are corrected using the coordinate transformation. Each corrected run-time image provides a distortion-free representation of a symbol that can be read by traditional code readers that normally cannot read distorted symbols. The method can handle both optical distortion and printing distortion. The method is applicable to “portable” readers when an incident angle with the surface is maintained, the reader being disposed at any distance from the surface.Type: GrantFiled: January 6, 2011Date of Patent: December 4, 2012Assignee: Cognex Technology and Investment CorporationInventors: Xiangyun Ye, Sateesha Nadabar

Patent number: 8267322Abstract: The present invention is a system and method for decoding an image of a bar code. Decoding the barcode includes tokenizing a plurality of pixels in the image of the barcode based upon a plurality of thresholds to form a first set of tokens. Decoding the barcode also includes re-tokenizing the plurality of pixels in the image of the barcode based upon the intensity of the pixels in the plurality of tokens, and the relativity intensity of neighboring tokens, to form a second set of tokens.Type: GrantFiled: March 8, 2010Date of Patent: September 18, 2012Assignee: Seiko Epson CorporationInventors: Jia Li, Mikhail Brusnitsyn, Eunice Poon, Seungsik Kwak, Guoyi Fu

Patent number: 8267321Abstract: A method of decoding a two-dimensional enhanced-density barcode. A first and a second barcode are encoded in the enhanced-density barcode. The enhanced-density barcode includes a set of blocks. Each block includes a predefined number of sub-pixels. The blocks of the enhanced-density barcode being arranged relatively to each other in a geometrical lattice having a first and a second lattice direction. The method includes the steps of distorting of the enhanced-density barcode in the first lattice direction, resulting in a first distorted barcode, distorting of the enhanced-density barcode in the second lattice direction, resulting in a second distorted barcode, reconstructing the first barcode by low-pass filtering the first distorted barcode, reconstructing the second barcode by low-pass filtering the second distorted barcode.Type: GrantFiled: February 6, 2009Date of Patent: September 18, 2012Assignee: International Business Machines CorporationInventors: Michael Peter Kuyper-Hammond, Michael Charles Osborne, Tamas Visegrady

Patent number: 8259941Abstract: In an MFP, an image on an original is read and the image is stored as a document (input image) in an HDD. A marking-information generation module generates marking information (two-dimensional code information) expressing at least one of information relating to storage of the document and an output parameters of the document. A document-relevance-information management module relates the marking information to the stored image, and an encryption/decryption module encrypts the marking information. A marking generation module generates a marking image from the encrypted marking information, and the marking image is printed out.Type: GrantFiled: July 24, 2008Date of Patent: September 4, 2012Assignee: Ricoh Company, LimitedInventor: Shinsuke Yanazume
