This paper attempts to estimate a 3D shape of human torso from 2 pictures which are front and side silhouette of a subject. Our method assumes that input pictures have accurate contours of a subject's body. And regions of torsos are extracted manually from input pictures. We use a deformable body model for estimation. This model is generated by principal component analysis to a homologous model database which is made of whole body scanned data. A result shape is computed by optimizing some deformation parameters of the model with comparing model's silhouettes and input silhouettes.
