Within this survey an attempt is made to document the present status of video surveillance
systems. The main components of a surveillance system are presented and studied …

Monitoring of human and social activities is becoming increasingly pervasive in our living
environment for public security and safety applications. The recognition of suspicious events …

Although surveillance video cameras are now widely used, their effectiveness is
questionable. Here, we focus on the challenging task of monitoring crowded events for …

Action localization networks are often structured as a feature encoder sub-network and a
localization sub-network, where the feature encoder learns to transform an input video to …

In the last decades, several systems based on video analysis have been proposed for
automatically detecting accidents on roads to ensure a quick intervention of emergency …

In the context of non-speech audio recognition and classification for multimedia applications,
it becomes essential to have a set of features able to accurately represent and discriminate …

Although research in audio recognition has traditionally focused on speech and music
signals, the problem of environmental sound recognition (ESR) has received more attention …

Acoustic event detection is essential for content analysis and description of multimedia
recordings. The majority of current literature on the topic learns the detectors through fully …

In this paper we propose a novel method for the detection of audio events for surveillance
applications. The method is based on the bag of words approach, adapted to deal with the …

Given an audio-visual pair, audio-visual segmentation (AVS) aims to locate sounding
sources by predicting pixel-wise maps. Previous methods assume that each sound …
