RIC-CNN: Rotation-Invariant Coordinate Convolutional Neural Network
Hanlin Mo, Guoying Zhao
In recent years, convolutional neural network has shown good performance in many image processing and computer vision tasks. However, a standard CNN model is not invariant to image…
Geometric Graph Representation with Learnable Graph Structure and Adaptive AU Constraint for Micro-Expression Recognition
Jinsheng Wei, Wei Peng, Guanming Lu +3
Micro-expression recognition (MER) is valuable because micro-expressions (MEs) can reveal genuine emotions. Most works take image sequences as input and cannot effectively explore…
Learning Optimal K-space Acquisition and Reconstruction using Physics-Informed Neural Networks
Wei Peng, Li Feng, Guoying Zhao +1
The inherent slow imaging speed of Magnetic Resonance Image (MRI) has spurred the development of various acceleration methods, typically through heuristically undersampling the MRI…
Uncertain Label Correction via Auxiliary Action Unit Graphs for Facial Expression Recognition
Yang Liu, Xingming Zhang, Janne Kauttonen +1
High-quality annotated images are significant to deep facial expression recognition (FER) methods. However, uncertain labels, mostly existing in large-scale public datasets, often…
Flexible-Modal Face Anti-Spoofing: A Benchmark
Zitong Yu, Ajian Liu, Chenxu Zhao +3
Face anti-spoofing (FAS) plays a vital role in securing face recognition systems from presentation attacks. Benefitted from the maturing camera sensors, single-modal (RGB) and mult…
Gaussian-Hermite Moment Invariants of General Multi-Channel Functions
Hanlin Mo, Hua Li, Guoying Zhao
With the development of data acquisition technology, large amounts of multi-channel data are collected and widely used in many fields. Most of them, such as RGB images and vector f…
