White Paper: Video Compression for CCTV

Can we ID from CCTV: image quality in digital CCTV and face identification performance

CCTV is used for an increasing number of purposes, and the new generation of digital systems can be tailored to serve a wide range of security requirements. However, configuration decisions are often made without considering specific task requirements, e.g. the video quality needed for reliable person identification. Our study investigated the relationship between video quality and the ability ...

overview of ways to enhance the security of video surveillance networks using blockchain

In recent decades, video surveillance systems have an increasing development that are used to prevent crime and manage facilities with rapid diffusion of  (CCTV)cameras to prevent crime and manage facilities. The video stored in the video surveillance system should be managed comfortably, but sometimes the movies are leaking out to unauthorized people or by unauthorized people, thus violating i...

The right Video Compression for Digital CCTV

Acceptable bit-rates for human face identification from CCTV Imagery

The objective of this investigation is to produce recommendations for acceptable bit-rates of CCTV footage of people onboard London buses. The majority of CCTV recorders on buses use a proprietary format based on the H.264/AVC video coding standard, exploiting both spatial and temporal redundancy. Low bit-rates are favored in the CCTV industry but they compromise the image usefulness of the rec...

Retrieval in Long Surveillance Videos using User-Described Motion & Object Attributes

We present a content-based retrieval method for long surveillance videos in wide-area (Airborne) and near-field (CCTV) imagery. Our goal is to retrieve video segments, with a focus on detecting objects moving on routes, that match user-defined events of interest. The sheer size and remote locations where surveillance videos are acquired necessitates highly compressed representations that are al...
