WORKSHOP GOALS:

The 1st issue of this workshop took place in June 2006 at Dagstuhl/Germany, co-chaired by B. Rosenhahn, D. Metaxas, and R. Klette. This 2nd issue will accompany ICCV 2007.

 

Modeling, tracking and understanding of human motion based on image sequences (such as video) is a field of research of increasing importance,  with applications in sports sciences, medicine, biomechanics, animation (avatars), surveillance, and so forth. Progress in human motion analysis depends on research in computer graphics, computer vision and biomechanics.  Though these fields of research are often treated separately, human motion analysis requires an interaction of computer graphics with computer vision, which also benefits from an understanding of biomechanic constraints.

 

Eadweard Muybridge (1830-1904) is known as the pioneer in motion capturing with his famous experiments in 1887 called ``Animal Locomotion'' (Do all feet leave the ground during the gallop of a horse? He used photography to answer the question.) The field of animal or human motion analysis has developed into many directions since then. However, human-like animation and recovery of motion is still far from being satisfactory. Various groups are dealing with different aspects of modeling, estimation and animation of human motions. Motivations differ, and define directions of research. Examples of motivations are the analysis of movements for disease detection (hip dislocations, knee injuries etc.),  sports movement optimization (ski or high jumping, golf playing, swimming, etc.), the animation of avatars in movies  (e.g. Gollum in Lord of the Rings), or the realistic character animation in computer games.

 

The goal of this workshop is to encourage interaction and to post collaboration between researches in computer vision, animation, and biomechanics.  New results and specific research strategies will be discussed at the workshop to approach this highly complex field. The intention is to discuss theoretical fundamentals related to those issues and to specify open problems and major directions of further development in the field of human motion related to computer vision, computer graphics or biomechanics. The workshop encourages interdisciplinary (vision + graphics, biomechanics + vision, etc.) contributions.

TOPICS:

 

Paper  submissions are solicited in the following topics

 

  • Accurate and anatomically correct modeling of human beings (this includes surface representations, deformable modeling, models of joints, surface morphing, rendering etc.)
  • Image or video processing for human motion (tracking and pose estimation, etc.)
  • Biomechanic constraints during motion modeling and estimation (self occlusion handling, self collision avoidance, joint stiffness modeling, etc.)
  • Sensor fusion for human motion estimation (e.g., using cameras, structured lighting, or a laser range scanner).
  • Learning human motion patterns.

 

Further subjects are possible as long as in the general field of the workshop.
