Cancelable biometric filters for face recognition

M Savvides, BVKV Kumar… - Proceedings of the 17th …, 2004 - ieeexplore.ieee.org
In this paper, we address the issue of producing cancelable biometric templates; a necessary
feature in the deployment of any biometric authentication system. We propose a novel …

Bounding box regression with uncertainty for accurate object detection

Y He, C Zhu, J Wang, M Savvides… - Proceedings of the …, 2019 - openaccess.thecvf.com
Large-scale object detection datasets (eg, MS-COCO) try to define the ground truth bounding
boxes as clear as possible. However, we observe that ambiguities are still introduced …

Local binary convolutional neural networks

…, V Naresh Boddeti, M Savvides - Proceedings of the …, 2017 - openaccess.thecvf.com
We propose local binary convolution (LBC), an efficient alternative to convolutional layers in
standard convolutional neural networks (CNN). The design principles of LBC are motivated …

How to generate spoofed irises from an iris code template

S Venugopalan, M Savvides - IEEE Transactions on …, 2011 - ieeexplore.ieee.org
Biometrics has gained a lot of attention over recent years as a way to identify individuals. Of
all biometrics-based techniques, the iris-pattern-based systems have recently shown very …

Feature selective anchor-free module for single-shot object detection

C Zhu, Y He, M Savvides - … of the IEEE/CVF conference on …, 2019 - openaccess.thecvf.com
We motivate and present feature selective anchor-free (FSAF) module, a simple and effective
building block for single-shot object detectors. It can be plugged into single-shot detectors …

Freematch: Self-adaptive thresholding for semi-supervised learning

…, W Hou, Y Fan, Z Wu, J Wang, M Savvides… - arXiv preprint arXiv …, 2022 - arxiv.org
Pseudo labeling and consistency regularization approaches with confidence-based
thresholding have made great progress in semi-supervised learning (SSL). In this paper, we …

Usb: A unified semi-supervised learning benchmark for classification

…, S Nakamura, W Ye, M Savvides… - Advances in …, 2022 - proceedings.neurips.cc
Semi-supervised learning (SSL) improves model generalization by leveraging massive
unlabeled data to augment limited labeled samples. However, currently, popular SSL evaluation …

Deep reinforcement learning in computer vision: a comprehensive survey

…, VS Rathour, K Yamazaki, K Luu, M Savvides - Artificial Intelligence …, 2022 - Springer
Deep reinforcement learning augments the reinforcement learning framework and utilizes
the powerful representation of deep neural networks. Recent works have demonstrated the …

Reactnet: Towards precise binary neural network with generalized activation functions

Z Liu, Z Shen, M Savvides, KT Cheng - … Glasgow, UK, August 23–28, 2020 …, 2020 - Springer
In this paper, we propose several ideas for enhancing a binary network to close its accuracy
gap from real-valued networks without incurring any additional computational cost. We first …

Semantic relation reasoning for shot-stable few-shot object detection

…, U Ahmed, Z Shen, M Savvides - Proceedings of the …, 2021 - openaccess.thecvf.com
Few-shot object detection is an imperative and long-lasting problem due to the inherent long-tail
distribution of real-world data. Its performance is largely affected by the data scarcity of …
