Eigenheads for Reconstruction
نویسندگان
چکیده
A framework is presented for recovering the 3D structure and visual appearance of a human head from sparse data obtained from a real-time tracking system. An eigenvector decomposition of CyberWare-scanned heads is used to code incoming information. Modular eigenspaces are used to decorrelate eigenfeatures (eyes, nose, and mouth) from the rest of the head data. We observe that the modular eigenspace encoding often does not perform as well as a single eigen-space, and ooer reasons for this based on experimental evidence.

Silhouette-Based 3D Face Shape Recovery
The creation of realistic 3D face models is still a fundamental problem in computer graphics. In this paper we present a novel method to obtain the 3D shape of an arbitrary human face using a sequence of silhouette images as input. Our face model is a linear combination of eigenheads, which are obtained by a Principal Component Analysis (PCA) of laser-scanned 3D human faces. The coefficients of...
متن کاملUse of Local Perforator Flaps for Post Burn Reconstruction
BACKGROUND Mainstay of post-burn reconstruction is release and split skin grafting. Pedicle flaps are cumbersome to the patient, require multiple procedures and hospitalization. Free flaps are technically demanding and facilities are not universally available. Here we evaluated the local perforator flaps for post-burn reconstruction. METHODS We have used sixteen perforator propellar flaps fo...

Background & objective: Trees, as an influential element, have an important role in post disaster reconstruction in four aspects; they can be used as "temporary settlement materials", "reviving collective memories", "creating calm” and “motivation for reconstruction". In addition, as "living memorials”, they remind the disaster and indicate the necessity of preparedness and resilience of societ...
