Abstract :
This paper presents a model to reconstruct 3D virtual humans based on a single and spontaneous image. The main goal is to use computer vision and pattern recognition techniques to build coherent virtual humans according to an input picture. To achieve this goal we provide a semi-automatic process that includes 3D posture detection, segmentation of human body parts, and silhouette processing. Such information is used to generate a 3D virtual human, which can be further animated. The approach proposed in this paper aims to speed up the creation of 3D articulated characters, providing avatars based on pictures. Experimental results indicate that our approach is a good option for generating virtual humans from images based on a few mouse clicks.
