Patent number: 10181088Abstract: A system and method for performing foreground/background separation on an input image. The method identifies a corresponding model visual element in a scene model associated with the input image, the model visual element being associated with a set of element models, each element model including a plurality of visual data sets. Select an element model from the set of element models, dependent upon a visual distance between the input visual element and a visual data set of the selected element model satisfying a predetermined criterion. The method classifies the input visual element as one of foreground and background, dependent upon the selected element model, and then updates each visual data set in the selected element model, dependent upon the input visual element and at least first and second different methods of updating a visual data set.Type: GrantFiled: October 20, 2011Date of Patent: January 15, 2019Assignee: Canon Kabushiki KaishaInventors: Amit Kumar Gupta, Ashley Partis, Xin Yu Liu

Patent number: 8837781Abstract: Disclosed herein are a computer-implemented method and a camera system for determining a current spatial representation for a detection in a current frame of an image sequence. The method derives an expected spatial representation (820) for the detection based on at least one previous frame, generates a spatial representation (810) of the detection, and extends the spatial representation (810) to obtain an extended spatial representation (830), based on the expected spatial representation (820). The method determines a similarity measure between the extended spatial representation (830) and the expected spatial representation (820), and then determines the current spatial representation for the detection based on the similarity measure.Type: GrantFiled: October 29, 2013Date of Patent: September 16, 2014Assignee: Canon Kabushiki KaishaInventors: Peter Jan Pakulski, Daniel John Wedge, Ashley Partis, David Kenji See

Patent number: 8837823Abstract: Disclosed herein are a system and method for performing foreground/background separation on an input image. The method pre-classifies (1010, 1020) an input visual element in the input image as one of a first element type and a second element type, dependent upon a predetermined characteristic. The method performs a first foreground/background separation (1030) on the input visual element that has been pre-classified as the first element type, wherein the first foreground/background separation step is based on color data and brightness data of the input visual element. The method performs a second foreground/background separation (1040) on the input visual element that has been pre-classified as the second element type, wherein the second foreground/background separation step is based on color data, brightness data, and texture of the input visual element.Type: GrantFiled: October 25, 2011Date of Patent: September 16, 2014Assignee: Canon Kabushiki KaishaInventors: Ashley Partis, Amit Kumar Gupta, Peter Jan Pakulski, Qianlu Lin
