Sparse Hidden Markov Models for Surgical Gesture Classification and Skill Evaluation
We consider the problem of classifying surgical gestures and skill level in robotic surgical tasks. Prior work in this area models gestures as states of a hidden Markov model (HMM) whose observations are discr...

In Defence of Negative Mining for Annotating Weakly Labelled Data
We propose a novel approach to annotating weakly labelled data. In contrast to many existing approaches that perform annotation by seeking clusters of self-similar exemplars (minimising intra-class variance), ...

Dual-Force Metric Learning for Robust Distracter-Resistant Tracker
In this paper, we propose a robust distracter-resistant tracking approach by learning a discriminative metric that adaptively learns the importance of features on-the-fly. The proposed metric is elaborately de...

A Unifying Theory of Active Discovery and Learning
For learning problems where human supervision is expensive, active query selection methods are often exploited to maximise the return of each supervision. Two problems where this has been successfully applied ...

Gait Recognition by Ranking
The advantage of gait over other biometrics such as face or fingerprint is that it can operate from a distance and without subject cooperation. However, this also makes gait subject to changes in various covar...

A Novel Visual Organization Based on Topological Perception
What are the primitives of visual perception? The early feature-analysis theory insists on it being a local-to-global process which has acted as the foundation of most computer vision applications for the past...
