Patent number: 10540810Abstract: A method of rendering a graphical object comprises accessing a mapping relating a mesoscale structure and a light scattering parameter of a material to a perceptual appearance characteristic; determining a perceptual appearance characteristic of the graphical object, the graphical object reproduced on an interface to represent an object formed from the material, the perceptual appearance characteristic determined in accordance with the mapping using an initial mesoscale structure and a light scattering parameter of the material; receiving a signal indicating a modification in structure relating to the initial mesoscale structure; and determining, using the mapping, an adjustment of the light scattering parameter preserving the determined perceptual appearance characteristic, based on the modification of the initial mesoscale structure.Type: GrantFiled: June 14, 2018Date of Patent: January 21, 2020Assignee: CANON KABUSHIKI KAISHAInventors: Steven Richard Irrgang, Thai Quan Huynh-Thu, Juno Kim, Vanessa Jeanie Honson, Matthew Raphael Arnison

Patent number: 10198794Abstract: A system and computer-implemented method of altering perceptibility of depth in an image. The method comprises receiving a desired change in the perceptibility of depth in the image; receiving a depth-map corresponding to the image; and determining at least one characteristic of the image. The method further comprises applying an image process to the image, the image process varying in strength according to the depth map, and in accordance with a non-linear predetermined mapping relating a strength of the applied image process to a change in the perceptibility of depth, the mapping being determined with respect to the identified characteristic.Type: GrantFiled: December 16, 2016Date of Patent: February 5, 2019Assignee: Canon Kabushiki KaishaInventors: Nicolas Pierre Marie Frederic Bonnier, Anna Wong, Clement Fredembach, Peter Jan Pakulski, Steven Richard Irrgang

Patent number: 9066036Abstract: Disclosed is a method of generating an electronic document having an enclosed region with a fill color. The method receives a digital representation of a source document, the source document containing an enclosed region and at least one corresponding background region, the enclosed region overlapping at least a portion of the background region. A fill color is determined for the enclosed region from the digital representation as is a reference background color for the enclosed region from the corresponding background region of the digital representation. The method assigns a transparent fill color to the enclosed region based on a comparison of the determined fill color for the enclosed region with the reference background color and stores enclosed region with the transparent fill color to generate an electronic document.Type: GrantFiled: December 14, 2012Date of Patent: June 23, 2015Assignee: Canon Kabushiki KaishaInventors: Yu-Ling Chen, James Austin Besley, Steven Richard Irrgang

Patent number: 8532374Abstract: Disclosed is a method of classifying segmented contents of a scanned image of a document. The method comprise partitioning the scanned image into color segmented tiles at pixel level. The method then generates superpositioned segmented contents, each segmented content representing related color segments in at least one color segmented tile. Statistics are then calculated for each segmented content using pixel level statistics from each of the tile color segments included in segmented content, and then determines a classification for each segmented content based on the calculated statistics. The segmented content may be macroregions. The macroregions may form part of a multi-layered document representation of the document.Type: GrantFiled: December 3, 2008Date of Patent: September 10, 2013Assignee: Canon Kabushiki KaishaInventors: Yu-Ling Chen, Steven Richard Irrgang, Eric Wai-Shing Chong

Patent number: 8238666Abstract: A method (1100) of creating a document comprising a modifiable shape, is disclosed. The method analyzes an image to detect at least a graphical object. The method matches the detected graphical object with at least one of a plurality of predetermined modifiable closed-form non-textual template shapes (e.g., 420) comprising control parameters for modifying the closed-form non-textual template shape in a non-affine manner. The number of control parameters of the predetermined modifiable closed-form non-textual template shape is less than the number of sections making up the modifiable closed-form non-textual template shape. The method creates a document comprising the at least one modifiable closed-form non-textual template shape.Type: GrantFiled: November 28, 2007Date of Patent: August 7, 2012Assignee: Canon Kabushiki KaishaInventors: James Austin Besley, Eric Wai-Shing Chong, Khanh Phi Van Doan, Steven Richard Irrgang

Patent number: 7991233Abstract: A method (1100) of creating an editable document is disclosed. The method analyses a bitmap image to detect at least one bit map representation of a graphical object and a bitmap representation of a line object. The method matches the graphical object with one of a plurality of predetermined template shapes (e.g., 420), the template shape having one or more predetermined non-contiguous connection points. The method selects one of the predetermined connection points for the line object if at least one end of the line object is within a predetermined distance of the selected connection point and associates the line object with the selected connection point. The method creates an editable document comprising the template shape with the line object connected thereto, wherein the line object remains associated with the selected connection point upon the template shape being modified within the document such that the line object remains dynamically connected to the template shape.Type: GrantFiled: November 29, 2007Date of Patent: August 2, 2011Assignee: Canon Kabushiki KaishaInventors: James Austin Besley, Eric Wai-Shing Chong, Khanh Phi Van Doan, Steven Richard Irrgang

Patent number: 7991224Abstract: A method (100), an apparatus, and a computer program product for automatically producing a compact representation of a colour document are disclosed. In the method, a digital image of a colour-document page is segmented (110) into connected components in one-pass, block raster order. The digital image of the page is partitioned into foreground and background images using layout analysis (120) based on compact, connected-component statistics of the whole page. At least one portion of the background image where at least one portion of the foreground image obscures the background image is inpainting (520) in one-pass block raster order. The foreground and background images are combined (130) to form a compact document. A method, an apparatus, and a computer program product for segmenting a digital image comprising a plurality of pixels are also disclosed.Type: GrantFiled: December 20, 2005Date of Patent: August 2, 2011Assignee: Canon Kabushiki KaishaInventors: James Philip Andrew, James Austin Besley, Steven Richard Irrgang, Yu-Ling Chen, Eric Wai-Shing Chong, Michael Jan Lawther, Timothy John Wark
