Privacy issues related to mass surveillance received unprecedented attention in 2013 and 2014. While the debate so far has focused on internet-based surveillance, the concerns raised by increased awareness of state surveillance capabilities have far reaching consequences for discussions on legislation relating to security, privacy and liberty in a range of domains. Focusing on train/metro trave...

Sewer flooding incidents in the UK are being increasingly associated with the presence of blockages. Blockages are difficult to deal with as although there are locations where they are more likely to occur, they do occur intermittently. In order to manage sewer blockage pro-actively sewer managers need to be able to identify the location of blockages promptly. Traditional closed-circuit televis...

This paper presents a novel approach for automatic people counting in videos captured through a conventional closed-circuit television (CCTV) using computer vision techniques. The proposed approach consists of detecting and tracking moving objects in video scenes to further counting them when they enters into a virtual counting zone defined in the scene. One of the main problems of using conven...

This paper focuses on automatic face identification for forensic applications. Forensic examiners compare different parts of the face image obtained from a closed-circuit television (CCTV) image with a database of mug shots or good quality image(s) taken from the suspect. In this work we study and compare the discriminative capabilities of different facial regions such as eye, eyebrow, mouth, e...

Facial comparison in 2D is an accepted method in law enforcement and forensic investigation, but pose variations, varying light conditions and low resolution video data can reduce the evidential value of the comparison. Some of these problems might be solved by comparing 3D face models: a face model derived from CCTV camera footage and a reference face model acquired from a suspect. In our case...

The problem of sequential detection of anomalies in multimodal data is considered. The objective is to observe physical sensor data from CCTV cameras, and social media data from Twitter and Instagram to detect anomalous behaviors or events. Data from each modality is transformed to discrete time count data by using an artificial neural network to obtain counts of objects in CCTV images and by c...

A key element for efficient video surveillance is situational awareness. Characteristics of human perception (e.g., inattentional blindness) as well as surveillance practice (e.g., CCTV operators have multiple responsibilities) often hinder comprehensive visual recognition of the activities in the monitored area. We support situational awareness and reduce the workload of CCTV operators by comp...
