Patent number: 9692929Abstract: A method for correcting an image acquired by a hand-held scanning device. A binarized image of an acquired image is cropped by removing columns on the left end and on the right end of only first components. A work image is created from the cropped image by replacing in each row of components series of first components smaller than a predetermined distance with series of second components. In the work image, a central line is identified. The identified central line in the work image is used to identify the corresponding central line in the cropped image forming a central line image, and in the central line image, the central text line is straightened.Type: GrantFiled: August 31, 2015Date of Patent: June 27, 2017Assignee: I.R.I.S.Inventors: Pierre De Muelenaere, Michel Dauw, Patrick Verleysen, Rene Barbier

Patent number: 9679179Abstract: A method implemented on a mobile device for selecting information on a paper document using a hand-held scanning device. The method provides an interface to the user, receives information from the hand-held pen scanning device connected to the mobile device and determines if the received information is valid information for the type of information to be selected. The invention further relates to using a remote computer for performing image processing and data extraction when more powerful resources are needed.Type: GrantFiled: August 31, 2015Date of Patent: June 13, 2017Assignee: I.R.I.S.Inventors: Pierre De Muelenaere, Michel Dauw, Patrick Verleysen, Rene Barbier

Patent number: 8463054Abstract: A pattern recognition process, a non-transitory computer program product, and a mobile terminal for pattern recognition. An input pattern is normalized and a reliable pattern is generated from the normalized pattern by using at least one morphological operator. The distance between the reliable pattern and selected templates which are selected from a template library using a decision tree, is calculated. The reliable patterns are classified into at least one of the classes of the selected templates by at least one non-parametric classification method.Type: GrantFiled: April 9, 2012Date of Patent: June 11, 2013Assignee: I.R.I.S.Inventors: Pierre De Muelenaere, Michel Dauw, Olivier Dupont, Patrick Verleysen

Patent number: 8411940Abstract: Method for up-scaling a color image prior to performing subsequent processing on said color image, comprising the steps of converting the color image into multiple image layers distinguishable from each other and up-scaling at least one of said multiple image layers. The up-scaling is tuned towards the subsequent processing, for example luminance is upscaled at higher quality than chrominance. Further, a method for interpreting information present on digitally acquired documents, comprising the steps of: (i) determining a country; (ii) identifying a list of languages and character sets in use in said country; (iii) performing optical character recognition simultaneously using all languages and character sets of the list; (iv) performing field parsing to identify fields in the digitally acquired document on the basis of international as well as country-specific field recognition rules; (v) storing the recognized information according to the identified fields in a database.Type: GrantFiled: August 14, 2008Date of Patent: April 2, 2013Assignee: I.R.I.S.Inventors: Michel Dauw, Patrick Verleysen, Xavier Gallez, Pierre De Muelenaere
