Patent number: 12067728Abstract: A heterogeneous image registration method includes: performing edge detection on collected images, in combination with a curvature scale space strategy to extract contour curved segments in an edge image. Implementing a feature point detection strategy based on global and local curvature detecting feature points in the contour curved segments, and obtaining the nearest minimum local curvature of the feature points pointing to starting and end points of the contour, respectively. Calculating the number of neighborhood sampling points and neighborhood auxiliary feature points of neighborhoods on both edges of each of the feature points according to the nearest minimum local curvature. Using neighborhood auxiliary feature points and feature points to form a feature triangle, calculating an angle bisector vector and a main direction corresponding to the feature point in the feature triangle.Type: GrantFiled: June 8, 2020Date of Patent: August 20, 2024Assignee: Shanghai Jiaotong UniversityInventors: Yadong Liu, Yingjie Yan, Qian Jiang, Ling Pei, Zhe Li, Peng Xu, Lei Su, Xiaofei Fu, Xiuchen Jiang

Patent number: 11810348Abstract: The present disclosure provide a method for identifying power equipment targets based on human-level concept learning, including: creating a dataset of power equipment images, and annotating power equipment in power equipment images; training neural network and Bayesian network with the annotated dataset and respectively acquire identification results and conditional probabilities; calculating probabilities of unions with the conditional probabilities; and filtering the identification result corresponding to the highest probability of the union as identification result of the dataset of the power equipment images and complete the identification of the power equipment. The present disclosure combines Mask R-CNN and probabilistic graphical model. The bottom layer uses Mask R-CNN, and the top layer uses Bayesian network to train in identifying power equipment images, so that a small amount of data samples can achieve good recognition, which improved the performance of Mask R-CNN model.Type: GrantFiled: March 24, 2021Date of Patent: November 7, 2023Assignee: Shanghai Jiaotong UniversityInventors: Yadong Liu, Yingjie Yan, Siheng Xiong, Ling Pei, Zhe Li, Peng Xu, Lei Su, Xiaofei Fu, Xiuchen Jiang

Patent number: 9088379Abstract: Embodiments of the present invention disclose a service transmission processing method, a node device and a network system are provided. One method includes: receiving service data after relay processing by a 3R relay node, where the relay processing includes terminating and regenerating an Optical Channel (OCh) of the service data, and when the OCh is terminated, transparent transmission is performed on an Optical channel Transport Unit (OTU); and performing defect detection on a path of the OTU to obtain a detection result of the path of the OTU. Another method includes: obtaining an overhead in an Optical Transport Network (OTN) frame; and judging whether the overhead includes a Client Signal Fail (CSF) inserted after a signal fails, and if the overhead includes the CSF, determining a path where a defect occurs according to the CSF.Type: GrantFiled: November 4, 2011Date of Patent: July 21, 2015Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jun Yan, Gen Chen, Bo Zhang, Da He, Yu Zeng, Ling Pei, Wei Tan, Min Chen, Xin Xiao
