Closed circuit television systems (CCTV) are becoming more popular and are being deployed in many offices, housing estates and in the most public spaces. Monitoring systems have been implemented in many foreign cities. This makes for an enormous load for the CCTV operators, as the number of camera views a single operator can monitor is limited by the human factors. The projects focus on the task of automated detection and recognition of dangerous situations for CCTV systems. We propose algorithms that are able to alert the human operator when a firearm is visible in the image and also have focussed on limiting the number of false alarms, in order to allow a real life application of the system. Managed to propose a version of a firearm detection algorithm that offers a near zero rate of false alarms and have shown that it is possible to create a system that are capable of an early warning in a dangerous situation, which may lead to faster and more effective response times and a reduction in the number of potential victims.

“…We have successfully applied MPEG-7 visual descriptors both in this work and in other research directed towards safety-related applications and computer forensics. Examples include the INACT Tool (an intelligent, advanced image cataloging tool [ 28 ] for combating child abuse) and the INSTREET Tool (an application for urban photograph localization [ 29 ]). Detection of dangerous objects is a specific case of general object detection, which can be carried out using methods, such as principal components analysis (PCA) [ 30 ], which is also applied in this work.…”

Closed circuit television systems (CCTV) are becoming more and more popular and are being deployed in many offices, housing estates and in most public spaces. Monitoring systems have been implemented in many European and American cities. This makes for an enormous load for the CCTV operators, as the number of camera views a single operator can monitor is limited by human factors. In this paper, we focus on the task of automated detection and recognition of dangerous situations for CCTV systems. We propose algorithms that are able to alert the human operator when a firearm or knife is visible in the image. We have focused on limiting the number of false alarms in order to allow for a real-life application of the system. The specificity and sensitivity of the knife detection are significantly better than others published recently. We have also managed to propose a version of a firearm detection algorithm that offers a near-zero rate of false alarms. We have shown that it is possible to create a system that is capable of an early warning in a dangerous situation, which may lead to faster and more effective response times and a reduction in the number of potential victims.

Online child pornography is a ubiquitous predicament over the internet, and its pessimistic effects and steady growth are significant in today's society. Online CSAM trading has recently gained much attention as well as “moral outrage” for national and international governments and law officials due to the ease of availability and sustained connectivity. The chapter is structured to highlight a deeper understanding of the term “CSAM” that is more diverse than the stigmatized expression of word child pornography and addresses the dark internet modalities frequently used by pedophiles to attract innocent victims. The authors also explored numerous innovative digital technologies and methods used by law enforcement officers around the world, together with corporate and non-governmental organizations to combat this unseen enemy.
