Patent number: 10346709Abstract: An enhanced object detecting method and apparatus is presented. A plurality of successive frames is captured by a monocular camera and the image data of the captured frames are transformed with respect to a predetermined point of view. For instance, the images may be transformed in order to obtain a top-down view. Particular features such as lines are extracted from the transformed image data, and corresponding features of successive frames are matched. An angular change of corresponding features is determined and boundaries of an object are identified based on the angular change of the features.Type: GrantFiled: July 18, 2017Date of Patent: July 9, 2019Assignee: APPLICATION SOLUTIONS (ELECTRONICS AND VISION) LTDInventors: Rui Guerreiro, Alexander Sibiryakov

Patent number: 8478051Abstract: A method of detecting a geometrically transformed object in an image comprises comparing a template comprising a plurality of line segments for the object with regions of an image, and determining a similarity measure that uses a statistical measure based on the sums of pixel values of line segments of the image corresponding to each of the line segments of the template. Embodiments of the invention use a discrete set of geometrically transformed versions of the template, for example using the similarity transform.Type: GrantFiled: March 20, 2008Date of Patent: July 2, 2013Assignee: Mitsubishi Electric CorporationInventor: Alexander Sibiryakov

Publication number: 20110150332Abstract: Blurred image data is sharpened by converting three channels of RGB data into a single channel of intensity data, processing the intensity data to generate integral image data, applying a variable size filter to the integral image data to generate box-filtered data, calculating a gain factor for each pixel position in dependence upon the box-filtered data, the intensity data and the size of the filter used for that pixel position, and multiplying the original RGB data of each pixel by the gain factor for that pixel to generate sharpened RGB data. The size of the filter is selected at each pixel position in dependence upon an estimate of the local amount of blur. In this way, as the amount of blur changes, the filter size changes appropriately. By processing the integral image data to generate box-filtered data, a constant number of processing operations are required for image sharpening irrespective of the size of filter that is used.Type: ApplicationFiled: May 19, 2009Publication date: June 23, 2011Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Alexander Sibiryakov, Miroslaw Bober

Publication number: 20100021065Abstract: There is described a method of processing a plurality of images to determine one or more groups of images with each group of images forming a panorama. The method comprises identifying distinctive features in each image, comparing a distinctive feature in one image with distinctive features in other images to identify possible matching features, and processing said possible matches to determine said one or more groups of images. When comparing distinctive features, a distinctive feature in one image is only compared with a subset of the distinctive features in the other images which satisfy one or more predefined criteria. The criteria could involve the similarity of the images, or alternatively whether or not a decision on registration has already been made for the pair of images concerned, hi this way, the number of feature comparisons is reduced.Type: ApplicationFiled: December 20, 2007Publication date: January 28, 2010Inventor: Alexander Sibiryakov
