Multiple Cameras in Smart Rooms: Analysis Strategies

Prof. Josep R. Casas

Abstract

Smart rooms are a paradigm of ambient intelligence and pervasive computing, providing an interesting combination of analysis from sensors, response through actuators and modeling of the situation for the development of consistent strategies in a particular "service" provided by the room. Technically speaking, a smart room is just an advanced computer interface, equipped with sensors and actuators. The tutorial starts from these concepts in order to justify the need of multiple cameras in a smart room for the unobtrusive analysis of the scene. After a brief discussion on the camera setup, framing and spatial coverage, the tutorial focuses on several visual analysis strategies and algorithms which may provide valid scene descriptions for the computer interface to work properly. A review on different fusion approaches for visual analysis in the context of a smart room introduces the description of the low level visual analysis tasks of person location and tracking, person identification, articulated body tracking and head-pose estimation. Higher level analysis requirements allow providing an insight into the more semantically meaningful analysis tasks of detection of focus of attention, gesture recognition or activity and event classification. Finally, the concept of smart room "service" is revisited for the closing of the tutorial, so that the set of visual analysis strategies described before are shown as integrated in a service environment.

Multimodal Human-centered Vision Systems

Prof. Nicu Sebe and Prof. Hamid Aghajan

Abstract

In this tutorial, we take a holistic approach to the human-centered visionsystems problem. We aim to identify the opportunities in addressing novel applications, and the potentials for fruitful future research directions in this area. In particular, we introduce key concepts, discuss technical approaches and open issues in three areas: (1) multimodal interaction: visual (body, gaze, gesture) and audio (emotion) analysis; (2) smart environments; (3) distributed and collaborative fusion of visual information. The tutorial sets forth application design examples in which a user-centric methodology is adopted across the different stages from feature and pose estimation in early vision to user behavior modeling in high-level reasoning. The role of query for user's feedback will be discussed with examples in smart home applications. The course will motivate the use of multiple sensors in the environment as well as contextual information for effective data and decision fusion, and will focus on the user interaction techniques formulated from the perspective of key human factors such as adaptation to user preferences and behavior models. Several applications based on the notion of user-centric design will be introduced and discussed.

Multi-camera and distributed video surveillance

Prof. Rita Cucchiara

Abstract

This tutorial addresses algorithms and techniques of computer vision and pattern recognition for multi-camera and distributed video surveillance. When multiple (heterogeneous) cameras are connected in a forest of sensors, standard techniques used in single- fixed camera surveillance are not sufficient anymore. Different approaches should be taken into account depending on the camera layout (e.g., with overlapped or not overlapped field of view), the camera motion (e.g., fixed or PTZ cameras), the network capability and the availability of computational resource in the smart camera for early processing. The tutorial aims at presenting a short survey of the research activities in this area, mainly focusing on people surveillance; models and algorithms for object segmentation and tracking in multi-camera environments will be presented in details with several demos from ImageLab of Modena. Techniques for people detection in cluttered environment will be presented. Finally, recent advances in trajectory analysis for people behaviour classification in distributed cameras systems will be discussed. Benchmark videos with ground truth and tutorial material will be available for the tutorial attendees.
