Patent number: 10789464Abstract: At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. Based on the registered image frames, the data processing unit produces eye/gaze tracking data with respect to the subject.Type: GrantFiled: April 9, 2019Date of Patent: September 29, 2020Assignee: Tobii ABInventors: Mattias Kuldkepp, Marten Skogo, Mattias Hanqvist, Martin Brogren, Dineshkumar Muthusamy

Patent number: 8478040Abstract: The present invention deals with an identification apparatus (100) in a video surveillance system for identifying properties of an object captured in a video sequence by a video surveillance camera. The identification apparatus comprises: an object identification unit (102) for identifying a specific object in a video sequence; a color histogram generator (104) for generating a color histogram in at least two dimensions of a color space based on color and intensity information of the specific object identified in the video sequence, the color and intensity information originating from a plurality of images of the video sequence; and an object properties identificator (106) for identifying properties of the object based on the generated color histogram. The identified properties can then be used in a tracking device (200) of the video surveillance system for tracking an object between different video sequences, which may be captured by two different video surveillance cameras.Type: GrantFiled: May 22, 2007Date of Patent: July 2, 2013Assignee: Axis ABInventors: Martin Brogren, Markus Skans, Johan Almbladh, Daniel Elvin
