Abstract muscle action procedures for human face animation

Abstract: A new way of controlling human face animation and synchronizing speech is proposed. It is based on the concept of abstract muscle action procedure (AMA procedure). An AMA procedure is a specialized procedure which simulates the specific action of a face muscle. This paper describes the new technique and presents a methodology for animating the face of synthetic actors based on three levels: the AMA-procedure level, the expression level and the script level. The role of multiple tracks is also emphasized. Pract… Show more

“…Here, we want to highlight a few approaches that have been taken to produce three-dimensional face animations (for a well-known example of highly realistic two-dimensional animation see [Ezzat et al 2002]). The earliest attempts at three-dimensional animation were based on abstract muscle parameterizations [Parke 1982;Magnenat-Thalmann et al 1988], as well as physical modeling of facial muscles using spring-masssystems [Terzopoulus and Waters 1990]. These were later extended to include skin deformations [Köhler et al 2002].…”

“…[Platt and Badler 1981] built a face model using masses and springs including forces generated by muscles, and made use of the Facial Action Coding System (FACS) [Ekman and Friesen 1978]. Other early work included [Waters 1987;Magnenat-Thalmann et al 1988;Kalra et al 1992]. [Lee et al 1995] constructed an anatomically motivated facial model based on scanned data, and endowed it with a mass spring system driven by muscle contractions.…”

“…Most of the existing parametric models of the human face have been developed in the perspective of optimizing the visual rendering of facial expressions (Parke, 1974;Platt & Badler, 1981;Bergeron & Lachapelle, 1985;Waters, 1987;Magnenat-Thalmann, Primeau, et al, 1988;Viaud & Yahia, 1992). Few models have focused on the specific articulation of speech gestures: Saintourens, Tramus, et al (1990); Benoît, Lallouache, et al (1992); Henton and Litwinovitz (1994) prestored a limited set of facial images occurring in the natural production of speech in order to synchronize the processes of diphone concatenation and visemes display in a text-to-audio-visual speech synthesizer.…”
