Reconstruction of 3D human hair shape from video captured images and CT data

We propose tree-dimensional (3D) reconstruction method of human hair-shape from rotating head multiple video captyred images and Ct data. It is well known that no hair is present on the polygonal skin surface of the human head (3D-head) reconstructed from CT or MRI data. Our task is to reconstruction and add the hair-shape on the 3D-head to create a realistics human head model for simulating post-surgical facial expressions. Using a sculpturing technique based upon rotating head images we proposed a method of reconstructing the hair-shape as well as concave and semi-occluded parts in the skin-hair junction regions. We have utilized binarized voxel data of the 3D-head (solid-head) in this regard. The sculpturing objects in our definition is the solid-head surrouded by assumed thick hair-voxels. We sculpture the surrounding hair-voxels according to the extracted hair-region from the video captured while keeping the internal solid-head intact. We reconstruct the concave and semi-occluded regions by digging up to the visible skin surface of the solid-head in/near the hair region. We define complete-model as the 3D polygonal surface obtained from solid-head including the resione sculptured hair-voxel on it. Experimentally we have shown that our method yields hair shape to be used in partice.
