A foreground detection system for automatic surveillance
… systems is concerned with accurately segmenting foreground objects from the static background in the videos. In this thesis we introduce a novel system for background subtraction, which takes a di erent approach than the conventional background subtraction systems. We make the assumption that the …

Unsupervised maritime target detection
The unsupervised detection of maritime targets in grey scale video is a difficult problem in maritime video surveillance. Most approaches assume that the camera is static and employ pixel-wise background modelling techniques for foreground detection; other methods rely on colour or thermal …

Robust Event Detection and Retrieval in Surveillance Video
We developed a robust event detection and retrieval system for surveillance video. The proposed system offers vision-based capabilities for the detection and tracking of various objects of interest, and can recognize events such as: 1. a person with certain attributes being present in the scene; 2. …

Optimization-Based Methods for Reconstruction and Structural Quantification of Neurons and Glia from Microscopic Images
… adaptive thresholding to achieve accurate foreground detection in noisy data. Then, GOMS3D formulates an optimization problem to project centerlines detected in 2D to 3D lines, thereby compensating for anisotropy, while MMS3D employs a front‑propagation algorithm that maximizes angular …

Saliency in audio and visual signals
… framework, we propose a novel image saliency detection algorithm and compare its performance with existing algorithms. This framework is also successfully applied to image sequences to detect foreground in dynamic scenes. Besides foreground detection, we also propose two new applications of …
