Patent number: 11321837Abstract: A flexible, artifact-free, and lensless fiber-based imaging system for biological objects. This system combines image reconstruction by a trained deep neural network with low-loss image transmission through disordered glass-air Anderson localized optical fiber. High quality images of biological objects can be obtained using short (few centimeters) or long (more than one meter) segments of disordered fiber with and without fiber bending. The deep neural network can also be designed to perform image classification. The system provides the unique property that the training performed within a straight fiber setup can be utilized for high fidelity reconstruction/classification of images that are transported through either straight or bent fiber making retraining for different bending situations unnecessary.Type: GrantFiled: June 10, 2020Date of Patent: May 3, 2022Assignee: University of Central Florida Research Foundation, Inc.Inventors: Shuo Pang, Yangyang Sun, Jian Zhao, Axel Schulzgen

Patent number: 11256918Abstract: In implementations of object detection in images, object detectors are trained using heterogeneous training datasets. A first training dataset is used to train an image tagging network to determine an attention map of an input image for a target concept. A second training dataset is used to train a conditional detection network that accepts as conditional inputs the attention map and a word embedding of the target concept. Despite the conditional detection network being trained with a training dataset having a small number of seen classes (e.g., classes in a training dataset), it generalizes to novel, unseen classes by concept conditioning, since the target concept propagates through the conditional detection network via the conditional inputs, thus influencing classification and region proposal. Hence, classes of objects that can be detected are expanded, without the need to scale training databases to include additional classes.Type: GrantFiled: May 14, 2020Date of Patent: February 22, 2022Assignee: Adobe Inc.Inventors: Zhe Lin, Xiaohui Shen, Mingyang Ling, Jianming Zhang, Jason Wen Yong Kuen
