| Abstract: |
| Motion Capture methods consist in techniques for recognition of movements of ordinary objects. Typically, motion capture systems based on mechanical, electromagnetic or acoustic devices have several problems which influences in the capture process. Therefore, the present work deals with optic based methods for the capture of human motion data without the use of special markings on the actor’s body. The implementation of such task comprehends the digitalization of video data, background scene removal, detection of moving objects in the video scene, analysis of the silhouette for objects in the scene, in order to detect the human being figure, segmentation of the silhouette for identification of the body parts’ 2D positioning, identification of the 3D positioning of the body parts and reconstitution of the movements in a 3D virtual marionette. This work presents innovative techniques for background scene removal and analysis of the silhouette for objects in the scene. The techniques presented here are original contributions to the literature. As validation for the considered method, a software prototype was developed using the Java language implements from the digitalization of video data to detection of the human being figure and part of the segmentation process of the human being figure. |
