Patent number: 8666185Abstract: A first aspect of the invention relates to a method for creating a binary mask image from an a inputted digital image of a scanned document, comprising the steps of creating a binarized image by binarizing the inputted digital image, detecting first text regions representing light text on a dark background, and inverting the first text regions, such that the inverted first text regions are interpretable in the same way as dark text on a light background. A second aspect of the invention relates to a method for comparing in a binary image a first pixel blob with a second pixel blob to determine whether they represent matching symbols, comprising the steps of detecting a line in one blob not present in the other and/or determining if one of the blobs represents an italicized symbol where the other does not.Type: GrantFiled: November 17, 2011Date of Patent: March 4, 2014Assignee: I.R.I.S.Inventors: Michel Dauw, Pierre Demuelenaere

Patent number: 8666190Abstract: The system and method of use are provided for correcting digital images based on the notions of local black points. The system and method are based on determining local black points in a digital image and correcting the intensities of nearby pixels so as to remove bias in the image introduced by atmospheric conditions. By sampling only localized land imagery the claimed method computes black points that are more robust against the localized effects of atmospheric and land reflection effects than black points computed from wider areas. The result of the method is that images corrected by this method are robust to atmospheric conditions that vary with time and viewing angle.Type: GrantFiled: February 1, 2011Date of Patent: March 4, 2014

Patent number: 8594722Abstract: A system and method for distributing at least one digital photographic image is presented, the system and method comprising at least one capturing device and at least one receiving device disposed in a communicative relation with one another via at least one wireless network. In particular, the capturing device is structured to capture the at least one digital photographic image via, for example, a capture assembly, whereas the receiving device is cooperatively structured to receive the digital photographic image via, for example, the at least one wireless network. In addition, the capturing device(s) and receiving device(s) may be disposed in a selectively paired relationship via one or more common pre-defined pairing criteria. Further, the at least one digital photographic image may be filtered via at least one pre-defined transfer criteria disposed on the capturing device and/or receiving device.Type: GrantFiled: March 26, 2013Date of Patent: November 26, 2013Assignee: SRR Patent Holdings, LLCInventor: Leigh M.

Patent number: 8577162Abstract: An output apparatus determines pixels that form an area equal to or greater than a predetermined size and whose pixel values are not different from pixel values of neighboring pixels, and pixels that form an area not equal to or greater than the predetermined size. The apparatus reduces the pixel values of the determined pixels and outputs a binary image formed by the determined pixels with the reduced pixel values.Type: GrantFiled: August 11, 2010Date of Patent: November 5, 2013Assignee: Fujitsu LimitedInventor: Shouichi Kuboyama

Patent number: 8553928Abstract: The present invention relates to an image processing method and image inspecting method with high versatility which enable efficient and highly accurate proof of authenticity of a digital image. The image processing method subjects at least a part of a digital image which can exist temporarily or continuously in a falsification-vulnerable environment, to a first morphology operation using a predetermined structuring element, to process the digital image. The image inspecting method subjects the digital image thus processed, to a second morphology operation using the same structuring element as in the first morphology operation. The morphology operations have the idempotent and the presence or absence of falsification can be detected by determining identity of images before and after the second morphology operation.Type: GrantFiled: March 6, 2007Date of Patent: October 8, 2013Assignees: Sumitomo Electric Industries, Ltd., Tokyo Metropolitan UniversityInventors: Hitoshi Kiya, Kiyoshi Nishikawa, Masaaki Fujiyoshi, Yoichi Hata, Toshiaki Kakii, Yoshimitsu Goto

Patent number: 8538163Abstract: A method for detecting edges within an image. An edge strength indicator for each pixel within the image is determined and the edge strength indicator is classified into at least three classes to generate a map having one value associated to each class. The classified map is then separated into individual maps depending on the classification. A dilation process is applied to at least a part of the individual maps. The processed and/or individual maps are finally combined by logical operation to obtain a final map indicating edges without nearby texture.Type: GrantFiled: September 29, 2010Date of Patent: September 17, 2013Assignee: Sony CorporationInventors: Frank Moesle, Paul Springer

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: 8437570Abstract: A method of geodesic image and video processing is proposed. In an embodiment, the method uses a geodesic distance transform to construct an image filter. The filter can be used in a variety of image editing operations such as segmentation, denoising, texture smoothing, image stitching and cartooning. In one embodiment, the method may be made efficient by utilizing parallelism of the algorithm to carry out processing steps on at least two processing cores concurrently. This efficiency may enable high-resolution images and video to be processed at ‘real time’ rates without the need for specialist hardware.Type: GrantFiled: May 23, 2008Date of Patent: May 7, 2013Assignee: Microsoft CorporationInventors: Antonio Criminisi, Toby Sharp
