Publication number: 20220044046Abstract: The present invention relates to a device, system and method for object recognition. To improve reliability and robustness of the recognition, the device comprises an input unit (21) configured to obtain a depth image (40) of a scene, a computation unit (22) that computes, from the depth image, a noise variance map (42) by computing pixel noise variances at object boundaries of one or more objects in the depth image, a depth confidence map (43) by filtering depth values based on their distance to the depth camera, and a motion confidence map (44) by filtering out variances caused by motion of a person in the scene. Further, from the noise variance map, the depth confidence map and the motion confidence map, one or more candidate regions (45) and their confidence in the depth image are computed, and the one or more candidate regions having the highest confidence are selected as final region of interest (41) representing the object to be recognized.Type: ApplicationFiled: December 16, 2019Publication date: February 10, 2022Inventors: SHAKITH DEVINDA FERNANDO, LU ZHANG, ESTHER MARJAN VAN DER HEIDE, THOMAS MARIA FALCK

Patent number: 11116423Abstract: The invention provides a patient monitoring system for monitoring a patient in a bed. A video camera is used for capturing video images of the patient. Video analysis is used to determine and track the position of body parts of the patient including the hands. This analysis is enhanced by using sensors which detect interaction by the patient with pieces of equipment in the vicinity of the bed.Type: GrantFiled: October 6, 2015Date of Patent: September 14, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Adrienne Heinrich, Thomas Falck, Esther Marjan Van Der Heide, Yingrong Xie, Frank Mueller

Patent number: 10720240Abstract: There is provided a context detection apparatus for use with a medical monitoring device arranged to measure a physiological characteristic of a subject. The context detection apparatus comprises at least one context sensor comprising a camera; and a processing unit. The processing unit is arranged to receive image data acquired by the camera from the at least one context sensor; analyze the received image data to generate a plurality of different types of context information; wherein each type of context information comprises information which relates to a factor capable of influencing measured values of the physiological characteristic and which is not measurable by the medical monitoring device; and output a signal to the medical monitoring device based on the generated context information.Type: GrantFiled: February 21, 2016Date of Patent: July 21, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Thomas Falck, Teun Van Den Heuvel, Esther Marjan Van Der Heide, Adrienne Heinrich, Yingrong Xie

Publication number: 20190076086Abstract: There is provided a method and apparatus for determining a baseline for one or more physiological characteristics of a subject. One or more physiological characteristics of a subject and contextual information associated with the subject is acquired. A time period in which the subject is in a baseline state is detected based on the acquired one or more physiological characteristics of the subject and the acquired contextual information associated with the subject. The baseline for the one or more physiological characteristics of the subject is determined from a value of at least one of the acquired one or more physiological characteristics in the detected time period.Type: ApplicationFiled: March 9, 2017Publication date: March 14, 2019Inventors: Jens MUEHLSTEFF, Johannes WEDA, Louis Nicolas ATALLAH, Esther Marjan VAN DER HEIDE
