Patent number: 9928418Abstract: A method for cropping photos images captured by a user from an image of a page of a photo album is described. Corners in the page image are detected using corner detection algorithm or by detecting intersections of line-segments (and their extensions) in the image using edge, corner, or line detection techniques. Pairs of the detected corners are used to define all potential quads, which are then are qualified according to various criteria. A correlation matrix is generated for each potential pair of the qualified quads, and candidate quads are selected based on the Eigenvector of the correlation matrix. The content of the selected quads is checked using a salience map that may be based on a trained neuron network, and the resulting photos images are extracted as individual files for further handling or manipulation by the user.Type: GrantFiled: August 12, 2017Date of Patent: March 27, 2018Assignee: PHOTOMYNE LTD.Inventors: Yair Segalovitz, Omer Shoor, Yaron Lipman, Nir Tzemah, Natalie Verter

Patent number: 9928452Abstract: This invention decodes image data without overwriting the decompression result of the first image data by that of the second image data when the first image data compressed by the first method and the second image data compressed by the second method coexist. To do this, when decoding the image data in which the first image data compressed by the first method and the second image data compressed by the second method different from the first method coexist, a lossy-decoding unit decodes the first image data. Based on boundary information indicating a compression region compressed by the second method, a lossless-decoding unit selectively outputs pixel data decoded by the lossy-decoding unit or pixel data obtained by decoding the second image data of the compression region.Type: GrantFiled: June 1, 2016Date of Patent: March 27, 2018Assignee: CANON KABUSHIKI KAISHAInventor: Takayuki Nagashima
