Publication number: 20230334846Abstract: Techniques are disclosed relating to automatically determining image quality for images of documents. In some embodiments, a computer system receives an image of a document captured at a user computing device. Using a neural network, the computer system analyzes the image to determine whether the image satisfies a quality threshold, where the analyzing includes determining whether one or more features in the image used in an authentication process are obscured. The computer system transmits, to the user computing device, a quality result, where the quality result is generated based on an image classification output by the neural network. Automatically determining whether a received image of a document satisfies a quality threshold may advantageously improve the chances of a system being able to complete an authentication process quickly, which in turn may improve user experience while reducing fraudulent activity.Type: ApplicationFiled: May 5, 2022Publication date: October 19, 2023Inventors: Chao Wang, Ke Jin, Yunfeng Ma, Wei Sun

Patent number: 11182906Abstract: Technology for performing object tracking of an object in a video image using both object detection algorithm and an object tracking algorithm. Because object detection algorithms are generally slower, but accurate, than object tracking algorithms, only certain sampled video frames are subject to the object detection algorithm. The non-sampled frames locate the object using the object tracking algorithm, using the most recent previous object detected frame as a starting frame. In this way, the object detection algorithm is used to periodically, effectively calibrate the object tracking algorithm by using a lagging detection result to hide latency introduced by the object detection algorithm.Type: GrantFiled: November 24, 2019Date of Patent: November 23, 2021Assignee: International Business Machines CorporationInventors: Yubo Li, Qing Wang, Ke Jin, Shi Lei Zhang, Jie Zhang
