The Research And Realize Of Expression Symbol In Cartoon Character Animation

With the advent of the digital age, traditional animation is experiencing arevolutionary transformation from2D to3D,with its unique visual form and aestheticrequirements,2D animation image are accepted by more people.; the animationimage with its visual world universal" language " has become a world cultural factorsinfluence. How effective will be three-dimensional and two-dimensional animationfusion to form a new aesthetic way has become an important research topic.2D cartoon character expressions tend to be more emotional mixed results, ishighly concentrated in human nature, is the real-life characters or character ofexaggeration and abstraction, because of the unique features of the plurality ofdifficult to be exact division for a specific expression category. Review existing facialexpression recognition technology are used to reference human facial feature,ignoring the two-dimensional cartoon facial expressions unique visual form andaesthetic emotion, for the two-dimensional cartoon character expression identificationand classification method is still not a uniform definition.The existing mainstream facial modeling and animation techniques can be finefor shaping the role of facial expressions and deformation of realistic, but due to theactual operation of these techniques the presence of facial model reconstructionprocess steps and details the complex and tedious, adjusting the speed is relativelyslow shortcomings; also because of the arrangement of deformation parametersvariety, in achieving the required repeated ratio selection of testing parameters, timeconsuming the lack of convenience.With the creation of the animation and animation courses in colleges isincreasing and related technology, using optimization techniques to improve theteaching process in the difficulty of realization, auxiliary teaching course of study will become extremely meaningful work.In view of this, this paper analysis of two-dimensional animation facialexpression feature, put forward train of thought and expression recognitionclassification method; optimized3D technique or method of realization and thedebugging are set reasonable parameter range.In this paper, the research focuses and main achievements of this thesis are asfollow:1. This paper introduces the main character animation facial expressionrecognition, facial modeling, animation and other aspects of the technology, and therole of facial expression recognition and3D technology realization way and the linkbetween their respective advantages and disadvantages are analyzed in detail.2. System analysis of two-dimensional cartoon facial expression feature andexpression classification, solves the cartoon facial expressions of individualdifference characteristics. cartoon characters reflect the characteristics of emotionexpression and restored its visual effect.3. Using Pixol towing point modeling expression model of shaping and localfeatures of expression adjustment, in order to improve the traditional modeling toolfor facial model reconstruction of complex process steps and tedious details, the rapidrealization of diversified expression characteristics of the model.4. A wire binding fusion expression of ideas, design uses a drive-by-wire methodbinding expression fusion expression parameter debugging, can rapidly on theexpression of capture, quick access to specific expression of the parameter values ofthe effect, the effective realization of interface interaction.5. According to the above theory and technology analysis, systematicallysummarizes the different types of expression symbol; on the facial expression ofsymbol design3D models, face model formation.
