Patent number: 10769480Abstract: An object detection method and a neural network system for object detection are disclosed. The object detection method acquires a current frame of a sequence of frames representing an image sequence, and extracts a feature map of the current frame. The extracted feature map is pooled with information of a pooled feature map of a previous frame to thereby obtain a pooled feature map of the current frame. An object is detected from the pooled feature map of the current frame. A dynamic vision sensor (DVS) may be utilized to provide the sequence of frames. Improved object detection accuracy may be realized, particularly when object movement speed is slow.Type: GrantFiled: August 27, 2018Date of Patent: September 8, 2020Assignees: SAMSUNG ELECTRONICS CO., LTD., BEIJING SAMSUNG TELECOM R&D CENTERInventors: Jia Li, Feng Shi, Weiheng Liu, Dongqing Zou, Qiang Wang, Hyunsurk Ryu, Keun Joo Park, Hyunku Lee

Patent number: 10636164Abstract: The disclosure provides an object detection method and apparatus based on a Dynamic Vision Sensor (DVS). The method includes the following operations of: acquiring a plurality of image frames by a DVS; and, detecting the image frames by a recurrent coherent network to acquire a candidate box for objects to be detected, wherein the recurrent coherent network comprising a frame detection network model and a candidate graph model. By using a new recurrent coherent detection network, a bounding box for an object to be detected is fast detected from the data acquired by a DVS. The detection speed is improved greatly while ensuring the detection accuracy.Type: GrantFiled: November 15, 2017Date of Patent: April 28, 2020Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jia Li, Qiang Wang, Feng Shi, Deheng Qian, Dongqing Zou, Hyunsurk Eric Ryu, JinMan Park, Jingtao Xu, Keun Joo Park, Weiheng Liu

Patent number: 10552973Abstract: Exemplary embodiments provide an image vision processing method, device and equipment and relate to: determining parallax and depth information of event pixel points in a dual-camera frame image acquired by Dynamic Vision Sensors; determining multiple neighboring event pixel points of each non-event pixel point in the dual-camera frame image; determining, according to location information of each neighboring event pixel point of each non-event pixel point, depth information of the non-event pixel point; and performing processing according to the depth information of each pixel point in the dual-camera frame image. Since non-event pixel points are not required to participate in the matching of pixel points, even if it is difficult to distinguish between the non-event pixel points or the non-event pixel points are occluded, depth information of the non-event pixel points can be accurately determined according to the location information of neighboring event pixel points.Type: GrantFiled: November 14, 2017Date of Patent: February 4, 2020Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dongqing Zou, Feng Shi, Weiheng Liu, Deheng Qian, Hyunsurk Eric Ryu, Jia Li, Jingtao Xu, Keun Joo Park, Qiang Wang, Changwoo Shin
