“…With multiple connected cameras and multiple sensors the problem of manage the wide amount of multimedia data will be not negligible; therefore, the choice and the organization of the semantic level of knowledge that is extracted and stored for further retrieving operation is particularly critical. For instance, the researches of Ebrahimi et al, [13], explore approaches for standard production of MPEG-7 cameras, capable to provide directly a MPEG-7 description of surveillance-related data; Lopes et al discusses the utility of MPEG-7 descriptions of audio and video data for surveillance [26]. Concerning the stream connectivity, an important focus of the next multimedia surveillance systems will be the process synchronization, the cooperative integration, the scheduling and the planning of the multiple stream productions.…”

The integration of video technology and sensor networks constitutes the fundamental infrastructure for new generations of multimedia surveillance systems, where many different media streams (audio, video, images, textual data, sensor signals) will concur to provide an automatic analysis of the controlled environment and a real-time interpretation of the scene. New solutions can be devised to enlarge the view of traditional surveillance systems by means of distributed architectures with fixed and active cameras, to enhance their view with other sensed data, to explore multi-resolution views with zooming and omnidirectional cameras. Applications regard surveillance of wide indoor and outdoor area and particularly people surveillance: in this case, multimedia surveillance systems can be enriched with biometric technology; the best views of detected persons and their extracted visual features (e.g. faces, voices, trajectories) can be exploited for people identification.VSSN05 is the third edition of the workshop, co-located at ACM Multimedia Conference, that embraces research reports on video surveillance and, since the edition of 2004, sensor networks. This paper gives a short overview of the hot topics in multimedia surveillance systems and introduces some research activities currently engaged in the world and presented at VSSN05.

“…To help filtering the adequate information out of the description, a priority list containing the priority of the parameters or descriptors for diverse users can be associated with the MPEG-7 content database ( Figure 5). Another application that has already been investigated 11,17 but asks for further developments are MPEG-7 compliant smart cameras. These devices output a XML description of visual scenes without any user intervention.…”

MPEG-7 description of generic video objects for scene reconstruction

We present an MPEG-7 compliant description of generic video sequences aiming at their scalable transmission and reconstruction. The proposed method allows efficient and flexible video coding while keeping the advantages of textual descriptions in database applications. Visual objects are described in terms of their shape, color, texture and motion; these features can be extracted automatically and are sufficient in a wide range of applications. To permit partial sequence reconstruction, at least one simple qualitative as well as a quantitative descriptor is provided for each feature. In addition, we propose a structure for the organization of the descriptors into objects and scenes and some possible applications for our method. Experimental results obtained with news and video surveillance sequences validate our method and highlight its main features.

“…A lot of research efforts in image privacy have focused on approaches to incorporate privacy protection into existing security surveillance systems and frameworks, typically, by implementing access rights management and privacy policies [2][3] [4]. Another large body of work is on the development of algorithms and methods to protect visual privacy, such as using watermarking to hide visual personal information [5], scrambling techniques to reversibly distort privacy sensitive regions [6], removal of unauthorized personnel from the video feed [7], and encoder independent geometrical-based reversible distortions [8] [9].…”

Abstract-With the popularization of online social networks (OSNs) and smart mobile devices, photo sharing is becoming a part of people' daily life. An unprecedented number of photos are being uploaded and shared everyday through online social networks or photo hosting services, such as Facebook, Twitter, Instagram, and Flickr. However, such unrestrained online photo or multimedia sharing has raised serious privacy concerns, especially after reports of citizens surveillance by governmental agencies and scandalous leakage of private photos from prominent photo sharing sites or online cloud services. Popular OSNs typically offer privacy protection solutions only in response to the public demand and therefore are often rudimental, complex to use, and provide limited degree of control and protection. Most solutions allow users to control either who can access the shared photos or for how long they can be accessed. In contrast, in this paper, we take a structured privacy by design approach to the problem of online photo privacy protection. We propose a privacy-preserving photo sharing architecture based on a secure JPEG scrambling algorithm capable of protecting the privacy of multiple users involved in a photo. We demonstrate the proposed photo sharing architecture with a prototype application called ProShare that offers JPEG scrambling as the privacy protection tool for selected regions in a photo, secure access to the protected images, and secure photo sharing on Facebook.
