Dictionary Learning and Sparse Coding on Grassmann Manifolds: An Extrinsic Solution
Mehrtash Harandi, Conrad Sanderson, Chunhua Shen +1
Recent advances in computer vision and machine learning suggest that a wide range of problems can be addressed more appropriately by considering non-Euclidean geometry. In this pap…
Dynamic Amelioration of Resolution Mismatches for Local Feature Based Identity Inference
Yongkang Wong, Conrad Sanderson, Sandra Mau +1
While existing face recognition systems based on local features are robust to issues such as misalignment, they can exhibit accuracy degradation when comparing images of differing…
Improved Anomaly Detection in Crowded Scenes via Cell-based Analysis of Foreground Speed, Size and Texture
Vikas Reddy, Conrad Sanderson, Brian C. Lovell
A robust and efficient anomaly detection technique is proposed, capable of dealing with crowded scenes where traditional tracking based approaches tend to fail. Initial foreground…
Patch-based Probabilistic Image Quality Assessment for Face Selection and Improved Video-based Face Recognition
Yongkang Wong, Shaokang Chen, Sandra Mau +2
In video based face recognition, face images are typically captured over multiple frames in uncontrolled conditions, where head pose, illumination, shadowing, motion blur and focus…
Video Face Matching using Subset Selection and Clustering of Probabilistic Multi-Region Histograms
Sandra Mau, Shaokang Chen, Conrad Sanderson +1
Balancing computational efficiency with recognition accuracy is one of the major challenges in real-world video-based face recognition. A significant design decision for any such s…
Spatio-Temporal Covariance Descriptors for Action and Gesture Recognition
Andres Sanin, Conrad Sanderson, Mehrtash T. Harandi +1
We propose a new action and gesture recognition method based on spatio-temporal covariance descriptors and a weighted Riemannian locality preserving projection approach that takes…
