Patent number: 11974811Abstract: This disclosure describes systems, devices, and techniques for training neural networks to identify avascular and signal reduction areas of Optical Coherence Tomography Angiography (OCTA) images and for using trained neural networks. By identifying signal reduction areas in OCTA images, the avascular areas can be detected with high accuracy, even when the OCTA images include artifacts and other types of noise. Accordingly, various implementations described herein can accurately identify avascular areas from real-world clinical OCTA images. In various implementations, a method can include identifying images of retinas. The images may include thickness images, reflectance intensity maps, and OCTA images of the retinas. Avascular maps corresponding to the OCTA images can be identified. A neural network can be trained based on the images and the avascular maps.Type: GrantFiled: April 24, 2020Date of Patent: May 7, 2024Assignee: OREGON HEALTH & SCIENCE UNIVERSITYInventors: Yali Jia, Yukun Guo

Patent number: 11974077Abstract: A system includes a sensor, a weight sensor, and a tracking subsystem. The tracking subsystem receives an image feed of top-view images generated by the sensor and weight measurements from the weight sensor. The tracking subsystem detects an event associated with an item being removed from a rack in which the weight sensor is installed. The tracking subsystem determines that a first person or a second person may be associated with the event. In response to determining that the first or second person may be associated with the event, buffer frames are stored of top-view images generated by the sensor during a time period associated with the event. The tracking subsystem then determines, using at least one of the stored buffer frames and a first action-detection algorithm, whether an action associated with the event was performed by the first person or the second person.Type: GrantFiled: October 15, 2020Date of Patent: April 30, 2024Assignee: 7-ELEVEN, INC.Inventors: Shahmeer Ali Mirza, Sailesh Bharathwaaj Krishnamurthy, Sarath Vakacharla, Deepanjan Paul
