چکیده

We propose an efficient real-time method for markerless 3D human motion capture that requires a single computer. Using input from at least three calibrated webcams, an extended ”Shape from Silhouette” algorithm reconstructs the filmed person in real-time. Fasts 3D shape and 3D skin parts analysis provide a robust and real-time system for human full-body tracking. Animation skeleton and simple morphological constraints ease the motion capture process. Thanks to fast and simple algorithms, and appliance to low-cost cameras, our system is well suited for home entertainment device. Results on long video sequences with fast and complex movements, demonstrate our approach robustness.

Generic Initialization for Motion Capture from 3D Shape

Real time and markerless motion capture is an active research area, due to applications in human-computer interactions, for example. A large part of the existing markerless motion capture methods require an initialization step, consisting in finding the initial position of the different limbs of the subject. In this paper, we propose a new method for interactive time initialization step, only b...

Markerless Motion Capture from Single or Multi-Camera Video Sequence

The modeling of human characters consists of two distinguished processes, namely the definition of 3D shape and 3D movement of the body. To achieve realism, both shape and motion information should be acquired from real persons. The two procedures are usually considered separately, by using full body scanners and motion capture systems. In this paper, we report about deterministic methods devel...

A framework for the functional identification of joint centers using markerless motion capture, validation for the hip joint.

The objective of the study was to develop a framework for the accurate identification of joint centers to be used for the calculation of human body kinematics and kinetics. The present work introduces a method for the functional identification of joint centers using markerless motion capture (MMC). The MMC system used 8 color VGA cameras. An automatic segmentation-registration algorithm was dev...
