Perceptual Organization is the process of establishing a meaningful relational structure over raw visual data so as visual primitives arising from the common physical cause are grouped together. A driving motivation behind perceptual organization research in computer vision is to deliver compact representations and to reduce the space of hypothesis for higher-level visual tasks. Since early demonstrations in the 1980s underscored its usefulness in object recognition, the computer vision community has seen various applications of PO in artificial vision systems such as in stereo matching, model indexing, contour completion, figure-ground segmentation, change detection, activity recognition, and more. Recent progress in PO has encouraged more participation from experts in related areas such as texture, motion analysis and recognition. Because of its wide applicability, the potential payoff from perceptual organization research is enormous.
The 6th IEEE POCV Workshop, to be held in conjunction with CVPR 2008 (Anchorage), will bring together experts in perceptual organization and related areas to report on recent research results and to provide ideas for future directions.

  • 2006 CVPR (New York, NY)
  • 2004 CVPR (Washington, DC)
  • 2001 ICCV (Vancouver, Canada)
  • 1999 ICCV (Crete, Greece)
  • 1998 CVPR (Santa Barbara, CA)
Papers are solicited in all areas of perceptual organization, including but not limited to:
  • image segmentation
  • contour completion
  • spatiotemporal/motion segmentation
  • figure-ground discrimination
  • integration of top-down and bottom-up methods
  • perceptual organization for object or activity detection/recognition
  • unification of segmentation, detection and recognition
  • biologically-motivated methods
  • neural basis for perceptual organization
  • learning in perceptual organization
  • graphical methods
  • natural scene statistics
  • evaluation methods
Research progress in perceptual organization depends in part on quantitative evaluation and comparison of algorithms. Authors reporting results of new algorithms are strongly encouraged to objectively quantify performance and compare against at least one competing approach.

Perceptual organization research faces a number of challenges. What kind of representation should they deliver? How can we quantify performance to allow objective evaluation and comparison between algorithms? To try to meet these challenges, we particularly encourage contributions of a more general nature that attempt to address one or more of these questions. These may include theoretical frameworks that might apply to multiple different perceptual organization problems, establishment of useful databases, modeling of underlying natural scene statistics, evaluation methodologies, etc.

Much of the current work in perceptual organization in computer vision has its roots in qualitative principles established by the Gestalt Psychologists nearly a century ago, and this link between computational and biological research continues to this day. Following this tradition, we specifically invite biological vision researchers working in the field of perceptual organization to submit work that may stimulate new directions of research in the computer vision community.

All accepted papers will be included in the Electronic Proceedings of CVPR, distributed on DVD at the conference, and will be indexed by IEEE Xplore. We are also exploring the possibility of a special journal issue on perceptual organization in computer vision, with a separate call for papers.

Submission is electronic, and must be in PDF format. Papers must not exceed 8 double-column pages. Submissions must follow standard IEEE 2-column format of single-spaced text in 10 point Times Roman, with 12 point interline space. All submissions must be anonymous. Please us the IEEE Computer Society CVPR format kit. Stay tuned for exact details on how to submit. In submitting a paper to the POCV Workshop, authors acknowledge that no paper of substantially similar content has been or will be submitted to another conference or workshop during the POCV review period.

  • Submission deadline: 11:59pm EST, March 31, 2008
  • Notification: April 25, 2008
  • Final versions of accepted papers due: May 1, 2008
