An End-to-End Autofocus Camera for Iris on the Move
Leyuan Wang, Kunbo Zhang, Yunlong Wang +1
For distant iris recognition, a long focal length lens is generally used to ensure the resolution ofiris images, which reduces the depth of field and leads to potential defocus blu…
CASIA-Face-Africa: A Large-scale African Face Image Database
Jawad Muhammad, Yunlong Wang, Caiyong Wang +2
Face recognition is a popular and well-studied area with wide applications in our society. However, racial bias had been proven to be inherent in most State Of The Art (SOTA) face…
All-in-Focus Iris Camera With a Great Capture Volume
Kunbo Zhang, Zhenteng Shen, Yunlong Wang +1
Imaging volume of an iris recognition system has been restricting the throughput and cooperation convenience in biometric applications. Numerous improvement trials are still imprac…
Recognition Oriented Iris Image Quality Assessment in the Feature Space
Leyuan Wang, Kunbo Zhang, Min Ren +2
A large portion of iris images captured in real world scenarios are poor quality due to the uncontrolled environment and the non-cooperative subject. To ensure that the recognition…
Alignment Free and Distortion Robust Iris Recognition
Min Ren, Caiyong Wang, Yunlong Wang +2
Iris recognition is a reliable personal identification method but there is still much room to improve its accuracy especially in less-constrained situations. For example, free move…
Dynamic Graph Representation for Partially Occluded Biometrics
Min Ren, Yunlong Wang, Zhenan Sun +1
The generalization ability of Convolutional neural networks (CNNs) for biometrics drops greatly due to the adverse effects of various occlusions. To this end, we propose a novel un…
