A Probabilistic Multi-phase Model for Variational Image Segmentation
Abstract. Recently, the Phase Field Method has shown to be a powerful tool for variational image segmentation. In this paper, we present a novel multi-phase model for probability b...

A variational segmentation framework using active contours and thresholding
Segmentation involves separating distinct regions in an image. In this note, we present a novel variational approach to perform this task. We propose an energy functional that nat...

Reconfigurable Control Variate Monte-Carlo Designs for Pricing Exotic Options
Exotic options are financial derivatives which have complex features including path-dependency. These complex features make them difficult to price, as only computationally intensi...
