Patent number: 11281899Abstract: Embodiments of the invention relate to a method for determining that an object in a sequence of images is a human. The method may include the steps of detecting an object in a first image from the sequence of images and assigning a first score to the object. The object is tracked to a second image from the sequence of images and a second score is assigned to the object in the second image. The second score is compared to a threshold that is inversely related to the first score and a determination that the object in the second image is a human is made based on the comparison.Type: GrantFiled: April 26, 2018Date of Patent: March 22, 2022Assignee: POINTGRAB LTD.Inventors: Ram Nathaniel, Moshe Nakash, Uri Zackhem

Patent number: 10049304Abstract: A method and system for detecting occupancy in a space use computer vision techniques. In one embodiment an object is detected in an image of the space. If the object is detected in a first area of the image, a shape of the object is determined based on a first shape feature of the object and if the object is detected in a second area of the image, the shape of the object is determined based on a second shape feature of the object. The object may be determined to be an occupant based on the determined shape of the object.Type: GrantFiled: January 10, 2017Date of Patent: August 14, 2018Assignee: POINTGRAB LTD.Inventors: Yonatan Hyatt, Benjamin Neeman, Jonathan Laserson

Patent number: 9483691Abstract: A system and method for computer vision based tracking of a human form may include detecting a shape of an object in an image of a space and determining the probability of object having a human form shape based on movement of the object. If the probability of the object of being of a human form is above a predetermined threshold the object is tracked and if the probability is below the threshold then the tracking is terminated.

Patent number: 8938124Abstract: A system and method for computer vision based tracking of a hand may include receiving a sequence of images, the images including at least one object having a shape of a hand. A first selected feature is tracked from within the hand shaped object. Shape recognition algorithms are applied at a suspected location of the hand shaped object in an image from the sequence of images to detect a shape of a hand in the image and a second feature from within the detected shape of the hand is then selected and tracked, thereby providing verification and updating of the location of the hand shaped object.Type: GrantFiled: June 25, 2013Date of Patent: January 20, 2015Assignee: Pointgrab Ltd.Inventors: Eran Eilat, Amir Kaplan, Ovadya Menadeva, Haim Perski
