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…
