Book Description
This unique books looks at a cost-efficient, fast and accurate means of facial reconstruction--from segmented, decomposed, or skeletal remains--using computer-graphic and computational means.Computer-Graphic Facial Reconstruction is designed as a valuable resource for those scientists designing new research projects and protocols, as well as a practical handbook of methods and techniques for medico-legal practitioners who actually identify the faceless victims of crime. It looks at a variety of approaches: artificial intelligence using neural networks, case-based reasoning, Baysian belief systems, along with a variety of imaging methods: radiological, CT, MRI and the use of imaging devices.The methods described in this book complement, or may even replace, the less-reliable, more traditional means of securing identification by presumptive means, i.e., recognition of clothing, personal effects and clay reconstruction.- Covers cutting-edge technologies in the context of historical forensic reconstruction methods- Features stellar authors from around the globe- Bridges the areas of computer graphics, animation, and forensic anthropology

Forensic Facial Reconstruction Using 3-D Computer Graphics
Author: Maria Vanezis
Publisher:
ISBN:

Languages : en
Pages : 317
Book Description
This thesis is concerned with computerised forensic 3-D facial reconstruction as a means of identification and involves the restoration of the face on the skull in an attempt to achieve a close likeness of the individual when alive. The reconstruction process begins with the biological identification of the skeletal remains, (age, sex, ancestry and build). Facial reconstruction is then carried out and essentially works by building the "face" up from the skull using soft tissue thicknesses at specific locations from existing data. However, it is used as a last resort on skeletonised, badly decomposed or mutilated corpses, when no other information is available; even then it is only accepted as corroborative evidence in court. It is performed in the hope that it may stimulate recognition, and consequently narrow the field of identification, allowing other tests to be carried out, such as radiographic and/or dental comparisons, DNA analysis or other means, to establish positive identification. The advantages of the computerised method over the manual clay reconstruction are speed, rapid editing capability, production of images that can be stored and reconstructions repeated at any time if required. Furthermore, in many cases, the original skull instead of a cast or model may be used for reconstruction because the 3-D computerised procedure is rapid and non invasive. However, the most significant advantage of this technique with regard to the aims and objectives of the thesis is that a number of alternative reconstructions may be produced sequentially for the same skull by using different facial templates from the database that meet the anthropological/biological criteria of the skull. The issues addressed by the study and therefore its main aims are: a) evaluation and b) improvement of the reliability of facial reconstruction using 3-D computer graphics.

A Deep Learning Approach to Facial 3D Reconstruction and Super-Resolution Rendering

Pages : 0
Book Description
Reconstructing 3D facial shapes is of significant interest in Computer Vision and Computer Graphics. In recent years, deep learning methods have been proposed for cost-effectively acquiring accurate 3D facial shapes. To some extent, these methods can generate accurate 3D facial shapes from a single image. Most of them assume that the resolution of the input images is high enough to reconstruct facial shapes, but this is not always the case, such as in the 3D reconstruction of players in a dynamic sports scene. Due to the large distances between players, one normally cannot acquire a photo showing all the players in focus and some faces could appear blurry. To tackle this problem, we propose a new learning-based architecture that combines a Super-Resolution (SR) network with a 3D Facial Reconstruction (FR) network. First, we input a low-resolution facial photo to the SR network, which generates corresponding SR images. These are input to the FR network, which generates corresponding facial shapes. We generate multiple SR images and corresponding 3D facial shapes because the SR network is a non-deterministic algorithm whose output is not always optimal for 3D reconstruction and rendering. Hence, we choose the best pair considering the noise level of the SR images and the distribution of distances among those facial shapes in order to reconstruct a good-quality 3D facial shape despite the low resolution of the input image.

Point-Based Graphics
Author: Markus Gross
Publisher: Elsevier
ISBN: 0080548822
Category : Computers
Languages : en
Pages : 553
Book Description
The polygon-mesh approach to 3D modeling was a huge advance, but today its limitations are clear. Longer render times for increasingly complex images effectively cap image complexity, or else stretch budgets and schedules to the breaking point. Comprised of contributions from leaders in the development and application of this technology, Point-Based Graphics examines it from all angles, beginning with the way in which the latest photographic and scanning devices have enabled modeling based on true geometry, rather than appearance. From there, it's on to the methods themselves. Even though point-based graphics is in its infancy, practitioners have already established many effective, economical techniques for achieving all the major effects associated with traditional 3D Modeling and rendering. You'll learn to apply these techniques, and you'll also learn how to create your own. The final chapter demonstrates how to do this using Pointshop3D, an open-source tool for developing new point-based algorithms. - The first book on a major development in computer graphics by the pioneers in the field - Shows how 3D images can be manipulated as easily as 2D images are with Photoshop
