The Workshop on Use of Context in Vision Processing (UCVP) offers a timely opportunity for the exchange of recent work on employing contextual information in problems of Computer Vision. Recent efforts in defining ambient intelligence applications based on user-centric concepts, the advent of technology in different sensing modalities, as well as the expanding interest in multi-modal information fusion, situation-aware and dynamic vision processing algorithms have created a common motivation across different research disciplines to utilize context as a key enabler of application-oriented vision. Improved robustness, efficient use of sensing and computing resources, dynamic task assignment to different operating modules, as well as adaptation to event and user behavior models are among the benefits a vision processing system can gain through the utilization of contextual information.

Aims and scope

UCVP aims to address the opportunities in incorporating contextual information in algorithm design for single or multi-camera vision systems, as well as systems in which vision is complemented with other sensing modalities, such as audio, motion, proximity, occupancy, and others. The objective of the workshop is to gather high-quality contributions describing leading-edge research in the use of context in vision processing. The workshop further aims to stimulate interaction among the participants through a panel discussion.

Topics of interest to the workshop include:

  • Sources of context:
    (multi-camera networks, multi-modal sensing systems, long-term observation, behavior models, spatial or temporal relationships of objects and events, interaction of user with objects, internet resources as knowledge-base for context extraction)
  • User-centric context:
    (demographic information, activity, user's emotional state, stated preferences, explicit and implicit interfaces, interaction between users)
  • Uses of context:
    (context-driven event interpretation, active vision, multi-modal activation, service provision and switching based on context, response and interaction with user, detection of abnormal behavior, active sensing, task assignment to different sensing modules, guided vision based on high-level reasoning, user behavior modeling, applications in smart environments, human-computer interfaces)

The workshop aims to encourage collaboration between researchers in different areas of computer vision and related disciplines. In addition, by introducing topics of emerging applications in smart environments, multi-camera networks, and multi-modal sensing as sources of context in vision, the workshop aims to extend the notion of context-based vision processing to include high-level and application-driven information extraction and fusion.
