Connecting the top-down to the bottom-up: Pricing CDO under a Conditional Survival (CS) model
In this paper, we use exact simulation to price CDO under a new dynamic model, the Conditional Survival (CS) model, which provided excellent calibration to both iTraxx tranches an...

Bayesian Modelling of Camera Calibration and Reconstruction
Camera calibration methods, whether implicit or explicit, are a critical part of most 3D vision systems. These methods involve estimation of a model for the camera that produced t...

Tracking Objects Across Cameras by Incrementally Learning Inter-camera Colour Calibration and Patterns of Activity
This paper presents a scalable solution to the problem of tracking objects across spatially separated, uncalibrated, non-overlapping cameras. Unlike other approaches this technique...
