Book Description
Adding texture to an object is extremely important for the enhancement of the 3D model's visual realism. This thesis presents a new method for mapping texture onto a 3D face model. The complete architecture of the new method is described. In this thesis, there are two main parts, one is 3D mesh modifying and the other is image processing. In 3D mesh modifying part, we use one face obj file as the 3D mesh file. Based on the coordinates and indices of that file, a 3D face wireframe can be displayed on screen by using OpenGL API. The most common method for mapping texture onto 3D mesh is to do mesh parametrization. To achieve this goal, a perspective-projection method is used to map 3D mesh to a 2D plane. To improve the degree of the accuracy, we separates the 3D mesh into three pieces based on three different view positions from left to right. In image processing part, we extracted the face information from the green background images by using image segmentation. Because of the three face images from different view positions, so they have different light illumination. In this thesis, a button controller was made to control the light illumination of three parts separately. The image blending method was used to reduce the texture seam between two different parts of the mesh.The proposed method in this thesis is new way to add detail to a 3D model. It provides a valid texture mapping, also satisfies the man-machine interaction exactly. Even if the images are taken under the different illumination, users can use keyboard to change its illumination for color matching. This new way provides a new method to parametrize and modify the mesh so as to be used for texture mapping.

Book Description
TheAMDO-e2006conferencetookplaceattheHotelMonPort, Portd'Andratx (Mallorca), on July 11-14, 2006, sponsored by the International Association for Pattern Recognition (IAPR), the MEC (Ministerio de Educaciþ on y Ciencia, SpanishGovernment), theConselleriad'Economia, HisendaiInnovaciþ o(Balearic Islands Government), the AERFAI (Spanish Association in Pattern Recognition and Arti?cial Intelligence), the EG (Eurographics Association) and the Ma- ematics and Computer Science Department of the UIB. Important commercial sponsorsalsocollaboratedwithpracticaldemonstrations;themaincontributions were from: VICOM Tech, ANDROME Iberica, GroupVision, Ndigital (NDI), CESA and TAGrv. The subject of the conference was ongoing research in articulated motion on a sequence of images and sophisticated models for deformable objects. The goals of these areas are to understand and interpret the motion of complex objects that can be found in sequences of images in the real world. The main topics considered as priority were: geometric and physical deformable models, motion analysis, articulated models and animation, modelling and visualization of deformable models, deformable models applications, motion analysis appli- tions, single or multiple human motion analysis and synthesis, face modelling, tracking, recovering and recognition models, virtual and augmented reality, haptics devices, biometrics techniques. These topics were grouped into four tracks: Track 1: Computer Graphics (Human Modelling and Animation), Track 2: Human Motion (Analysis, Tracking, 3D Reconstruction and Rec- nition), Track 3: Multimodal User Interaction (VR and AR, Speech, Biom- rics) and Track 4: Advanced Multimedia Systems (Standards, Indexed Video Contents). This conference was the natural evolution of the AMDO2004 workshop (Springer LNCS 3179).

Book Description
3D Face Modeling, Analysis and Recognition presents methodologies for analyzing shapes of facial surfaces, develops computational tools for analyzing 3D face data, and illustrates them using state-of-the-art applications. The methodologies chosen are based on efficient representations, metrics, comparisons, and classifications of features that are especially relevant in the context of 3D measurements of human faces. These frameworks have a long-term utility in face analysis, taking into account the anticipated improvements in data collection, data storage, processing speeds, and application scenarios expected as the discipline develops further. The book covers face acquisition through 3D scanners and 3D face pre-processing, before examining the three main approaches for 3D facial surface analysis and recognition: facial curves; facial surface features; and 3D morphable models. Whilst the focus of these chapters is fundamentals and methodologies, the algorithms provided are tested on facial biometric data, thereby continually showing how the methods can be applied. Key features: • Explores the underlying mathematics and will apply these mathematical techniques to 3D face analysis and recognition • Provides coverage of a wide range of applications including biometrics, forensic applications, facial expression analysis, and model fitting to 2D images • Contains numerous exercises and algorithms throughout the book
