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…
Sparse Coding and Dictionary Learning for Symmetric Positive Definite Matrices: A Kernel Approach
Mehrtash T. Harandi, Conrad Sanderson, Richard Hartley +1
Recent advances suggest that a wide range of computer vision problems can be addressed more appropriately by considering non-Euclidean geometry. This paper tackles the problem of s…
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…
Classification of Human Epithelial Type 2 Cell Indirect Immunofluoresence Images via Codebook Based Descriptors
Arnold Wiliem, Yongkang Wong, Conrad Sanderson +3
The Anti-Nuclear Antibody (ANA) clinical pathology test is commonly used to identify the existence of various diseases. A hallmark method for identifying the presence of ANAs is th…
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…
