Patent number: 11176691Abstract: A computing system obtains image data representing images. Each of the images is captured at different time points of a physical environment. The physical environment comprises a first object and a second object. The computing system executes a control system to augment the physical environment. The control system detects a group forming in the images. The control system tracks an aspect of a movement, of a given object, in the group. The control system simulates the physical environment and the movement, of the given object, in the group in a simulated environment. The control system evaluates simulated actions in the simulated environment for a predefined objective for the physical environment. The predefined objective is related to an interaction between objects in the group. The control system generates based on evaluated simulated actions and autonomously from involvement by any user of the control system, an indication to augment the physical environment.Type: GrantFiled: October 1, 2020Date of Patent: November 16, 2021Assignee: SAS Institute Inc.Inventors: Hamza Mustafa Ghadyali, Kedar Shriram Prabhudesai, Mohammadreza Nazari, Bahar Biller, Afshin Oroojlooyjadid, Alexander Richard Phelps, Jonathan Lee Walker, Xunlei Wu, Xingqi Du, Davood Hajinezhad, Varunraj Valsaraj, Jorge Manuel Gomes da Silva, Jinxin Yi

Patent number: 11176692Abstract: A computing system responsive to obtaining original image data, detects a set of data point(s), in the original image data, that indicates an object. The system determines, based on the set of data point(s), a set of pixels associated with the object in the original image data. The system generates an alternative visual identifier for the object that provides a unique identifier for the set of pixels absent in the original image data. The system generates, autonomously from intervention by any user of the computing system, pixel information to conceal feature(s) of the object. The system obtains modified image data comprising the alternative visual identifier. The modified image data further comprises the feature(s) of the object in the original image data visually concealed in the modified image data according to the pixel information. The system outputs an image representation of a trajectory of the object through the modified image data.Type: GrantFiled: October 1, 2020Date of Patent: November 16, 2021Assignee: SAS Institute Inc.Inventors: Hamza Mustafa Ghadyali, Kedar Shriram Prabhudesai, Jonathan Lee Walker, Xunlei Wu, Xingqi Du, Bahar Biller, Mohammadreza Nazari, Afshin Oroojlooyjadid, Alexander Richard Phelps, Davood Hajinezhad, Varunraj Valsaraj, Jorge Manuel Gomes da Silva, Jinxin Yi
