Book Description
Abstract: Expressive facial speech animation is a challenging topic of great interest to the computer graphics community. Adding emotions to audio-visual speech animation is very important for realistic facial animation. The complexity of neutral visual speech synthesis is mainly attributed to co-articulation. Co-articulation is the phenomenon due to which the facial pose of the current segment of speech is affected by the neighboring segments of speech. The inclusion of emotions and fluency effects in speech adds to that complexity because of the corresponding shape and timing modifications brought about in speech. Speech is often accompanied by supportive visual prosodic elements such as motion of the head, eyes, and eyebrow, which improve the intelligibility of speech, and they need to be synthesized. In this dissertation, we present a technique to modify input neutral audio and synthesize visual speech incorporating effects of emotion and fluency. Visemes, which are visual counterpart of phonemes, are used to animate speech. We motion capture 3-D facial motion and extract facial muscle positions of expressive visemes. Our expressive visemes capture the pose of the entire face. The expressive visemes are blended using a novel constraint-based co-articulation technique that can easily accommodate the effects of emotion. We also present a visual prosody model for emotional speech, based on motion capture data, that exhibits non-verbal behaviors such as eyebrow motion and overall head motion.

Book Description
Data-Driven 3D Facial Animation systematically describes the important techniques developed over the last ten years or so. Although 3D facial animation is used more and more in the entertainment industries, to date there have been very few books that address the techniques involved. Comprehensive in scope, the book covers not only traditional lip-sync (speech animation), but also expressive facial motion, facial gestures, facial modeling, editing and sketching, and facial animation transferring. It provides an up-to-date reference source for academic research and for professionals working in the facial animation field.

Book Description
Animated interactive characters and robots that are able to function in human social environments are being developed by a large number of research groups worldwide. Emotional expression, as a key element of human social interaction and communication, is often added in an attempt to make them appear more natural to us. How can such artefacts be given emotional displays that are believable and acceptable to humans? This is the central question of Animating Expressive Characters for Social Interaction. The ability to express and recognize emotions is a fundamental aspect of social interaction. Not only is it a central research question, it has been explored in animated films, dance, and other expressive arts for a much longer period. This book is unique in presenting a multi-disciplinary approach to animation in its broadest sense: from internal mechanisms to external displays, not only from a graphical perspective, but more generally examining how to give characters an “anima”, so that they appear as life-like entities and social partners to humans.

Book Description
Intelligent Expression Blending in PDFA Performance Driven Facial Animation (PDFA) provides a cost-effective and intuitive means of creating facial avatars. In Vision based PDFA, facial actions of an input facial video are re-targeted to desired facial model. However, PDFA lacks facilities for intelligent editing of the re- targeted video. This book discusses how to incorporate flexibility to PDFA so that resulting system can intelligently edit the input video on basis of contextual information. It advocates the use of Fuzzy Theory to automatically generate the facial actions that must be blended with the input video's facial actions to truly reflect the current context. These changes can then be translated into facial action parameters for synthesizing context- based facial expressions of the avatar.
