Patent number: 11669979Abstract: A camera system comprises an image capturing device, object detection module, object tracking module, and match classifier. The object detection module receives image data and detects objects appearing in one or more of the images. The object tracking module temporally associates instances of detected objects, each of which has a signature representing features of the detected object. The match classifier matches object instances by analyzing data derived from the signatures. The match classifier determines whether the signatures match.Type: GrantFiled: October 7, 2021Date of Patent: June 6, 2023Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Mahesh Saptharishi, Dimitri A.

Patent number: 10699115Abstract: A camera system comprises an image capturing device, and connected to it are an object classification module and a calibration module. The object classification module is operable to determine whether or not an object in an image is a member of an object class, and the calibration module is operable to estimate representative sizes of the object. The object classification module may determine a confidence parameter that is used by the calibration module, or conversely, the calibration module may produce a size that is used by the classification module.Type: GrantFiled: August 2, 2019Date of Patent: June 30, 2020Assignee: AVIGILON ANALYTICS CORPORATIONInventors: Mahesh Saptharishi, Dimitri A.

Patent number: 10133922Abstract: A camera system comprises an image capturing device and an object classification module connected to the image capturing device. The object classification module is operable to determine whether or not an object in an image is a member of an object class. The object classification module includes multiple decision steps configured in a cascade configuration, wherein at least one of the multiple decision steps is operable to (a) accept an object as a member of the object class, (b) reject an object as a member of the object class, and (c) call on a next step to determine whether or not an object is a member of the object class.Type: GrantFiled: December 5, 2014Date of Patent: November 20, 2018Assignee: AVIGILON ANALYTICS CORPORATIONInventors: Mahesh Saptharishi, Dimitri A.

Patent number: 9317753Abstract: A camera system comprises an image capturing device, object detection module, object tracking module, and match classifier. The object detection module receives image data and detects objects appearing in one or more of the images. The object tracking module temporally associates instances of a first object detected in a first group of the images. The first object has a first signature representing features of the first object. The match classifier matches object instances by analyzing data derived from the first signature of the first object and a second signature of a second object detected in a second image. The second signature represents features of the second object derived from the second image. The match classifier determine whether the second signature matches the first signature. A training process automatically configures the match classifier using a set of possible object features.Type: GrantFiled: February 18, 2014Date of Patent: April 19, 2016Assignee: AVIGILON PATENT HOLDING 2 CORPORATIONInventors: Mahesh Saptharishi, Dimitri A.

Patent number: 9319666Abstract: A device is configured to receive an image including a calibration pattern and apply a filter to the image based on a first coordinate plane. The device is configured to determine a first set of response peaks associated with the calibration pattern based on applying the filter, the first set of response peaks being associated with a set of control points and a set of boundary points. The device is configured to determine a second set of response peaks associated with the calibration pattern based on a second coordinate plane and a third coordinate plane, the second set of response peaks being associated with the boundary points. The device is configured to determine the control points based on determining the first set of response peaks and the second set of response peaks, and provide information that identifies the control points.Type: GrantFiled: June 3, 2013Date of Patent: April 19, 2016Assignee: The MathWorks, Inc.Inventor: Dimitri Lisin
