Patent number: 11935214Abstract: Presented herein are systems and methods for an end-to-end solution for object removal from a video using adaptive learning. In one or more embodiments, using a pre-trained image inpainting model, in-scene training data may be generated using optical-flow guided sampling. In one or more embodiments, the sampled patches are used to generate a training dataset, which is used to further train the image inpainting model until reaching a stop condition. The adaptively trained inpainting model may be used to generate a modified video in which the desired object or objects have been removed and the corresponding removed portion(s) have been filled (or inpainted) to preserve the integrity of the image.Type: GrantFiled: January 27, 2021Date of Patent: March 19, 2024Assignee: Baidu USA LLCInventors: Zhihong Pan, Daming Lu, Xi Chen

Publication number: 20220092381Abstract: Network architecture search (NAS) received a lot of attention. The supernet-based differentiable approach is popular because it can effectively share the weights and lead to more efficient search. However, the mismatch between the architecture and weights caused by weight sharing still exists. Moreover, the coupling effects among different operators are also neglected. To alleviate these problems, embodiments of an effective NAS methodology by similarity-based operator ranking are presented herein. With the aim of approximating each layer's output in the supernet, a similarity-based operator ranking based on statistical random comparison is used. In one or more embodiments, then the operator that possibly causes the least change to feature distribution discrepancy is pruned. In one or more embodiments, a fair sampling process may be used to mitigate the operators' Matthew effect that happened frequently in previous supernet approaches.Type: ApplicationFiled: September 18, 2020Publication date: March 24, 2022Applicants: Baidu USA LLC, Baidu.com Times Technology (Beijing) Co., Ltd.Inventors: Baopu LI, Yanwen FAN, Zhihong PAN, Teng XI, Gang ZHANG
