In this paper, we present a representation for three-dimensional geometric animation sequences. Different from standard key-frame techniques, this approach is based on the determination of principal animation components and decouples the animation from the underlying geometry. The new representation supports progressive animation compression with spatial, as well as temporal, level-of-detail an...

The MPEG-4 Face and Body Animation (FBA) specifications aims at standardizing an interchange format for specifying virtual face and body modeling and related animation parameters. The scene graph concept, the FBA nodes, semantics and representation of the animation parameters as well as compression and streaming capabilities are successively addressed. The compatibility between virtual characte...

Aesthetics of violence is a common film style and expression technique used in the creation 'adult-oriented' Chinese animation also form artistic exploration violence. The aesthetics relies on virtual world animation, putting bloody romantic poetic veneer, highlighting aesthetic feelings audience, at same time setting values as modern social values, turning into an allegorical "non-child" adult...

Animation art is displayed in front of people the form images, and have long been accustomed to attribute it image similar movies. In a narrow sense, expression anima-tion really single. If we look at generalized animation from original intention animation, has broader development space, there are more derivative possibilities interdisciplinary com-bination. Nowadays, pluralistic society, freed...

Machinima is digital visuals created with game engines that build real-time 3D CG (computer graphic) environment. Composition of scene and facial animation play important role in composition of Machinima’s videos. Character facial animation is frequently used in scene composition that mainly displays face and upper body of the character. Expressing character’s emotion is an important factor in ...

We propose a coupled hidden Markov model (CHMM) approach to video-realistic speech animation, which realizes realistic facial animations driven by speaker independent continuous speech. Different from hidden Markov model (HMM)-based animation approaches that use a singlestate chain, we use CHMMs to explicitly model the subtle characteristics of audio–visual speech, e.g., the asynchrony, tempora...

In recent years, visual models represented by graphs have become very popular in systems development, as the wide-spread use of UML and Petri nets proves. Visual modeling techniques provide an intuitive, yet precise way to model the structure and behavior of systems at their natural level of abstraction. Validating model behavior is one of the main aims of visual behavior modeling. To express t...

Traditional facial animation techniques require either an artist to create and/or clean the animation by hand, which is very time consuming, or rely on motion capture techniques, where fine tuning is usually still required. Generating facial animation becomes even slower when modelling the reactions to external stimuli. Procedural methods are an alternative to these approaches as they rely on a...

Literature on human animation [1] [2] [3] [4] [5] generally emphasizes the human modeling and the animation process. In three-dimensional character animation, the complexity of motion may be arbitrarily divided into three main areas: facial animation [6] [7] [8] [9] [10] [11] [12] [13], hand animation [14] [15] [16] and body animation [17] [18] [19] [20] [21] [22] [23]. In a previous paper [24]...
