Patent number: 11823050Abstract: A semi-supervised model incorporates deep feature learning and pseudo label estimation into a unified framework. The deep feature learning can include multiple convolutional neural networks (CNNs). The CNNs can be trained on available training datasets, tuned using a small amount of labeled training samples, and stored as the original models. Features are then extracted for unlabeled training samples by utilizing the original models. Multi-view clustering is used to cluster features to generate pseudo labels. Then the original models are tuned by using an updated training set that includes labeled training samples and unlabeled training samples with pseudo labels. Iterations of multi-view clustering and tuning using an updated training set can continue until the updated training set is stable.Type: GrantFiled: December 8, 2022Date of Patent: November 21, 2023Assignee: DEEP NORTH, INC.Inventors: Jinjun Wang, Xiaomeng Xin

Patent number: 10718951Abstract: Systems, devices, and methods for beam combining within laser projectors are described. A laser projector includes first, second, and third laser diodes to generate red, green, and blue laser light respectively, a controllable scan mirror, and a heterogeneous beam splitter system.
