A Data Driven Method for Multi-step Prediction of Ship Roll Motion in High Sea States
Dan Zhang, Xi Zhou, Zi-Hao Wang +2
Ship roll motion in high sea states has large amplitudes and nonlinear dynamics, and its prediction is significant for operability, safety, and survivability. This paper presents a…
Learning Discriminative Representations for Fine-Grained Diabetic Retinopathy Grading
Li Tian, Liyan Ma, Zhijie Wen +2
Diabetic retinopathy (DR) is one of the leading causes of blindness. However, no specific symptoms of early DR lead to a delayed diagnosis, which results in disease progression in…
Proximal Policy Optimization with Mixed Distributed Training
Zhenyu Zhang, Xiangfeng Luo, Tong Liu +5
Instability and slowness are two main problems in deep reinforcement learning. Even if proximal policy optimization (PPO) is the state of the art, it still suffers from these two p…
A Novel Method for Extrinsic Calibration of Multiple RGB-D Cameras Using Descriptor-Based Patterns
Hang Liu, Hengyu Li, Xiahua Liu +3
This letter presents a novel method to estimate the relative poses between RGB-D cameras with minimal overlapping fields of view in a panoramic RGB-D camera system. This calibratio…
Construction of all-in-focus images assisted by depth sensing
Hang Liu, Hengyu Li, Jun Luo +2
Multi-focus image fusion is a technique for obtaining an all-in-focus image in which all objects are in focus to extend the limited depth of field (DoF) of an imaging system. Diffe…
