Sketch-Based Facial Animation
نویسنده
چکیده
We present a sketch-based interface for animating virtual face models. Our approach first converts an input sketch into a set of strokes (curves). Each stroke is automatically associated with a facial element, such as eyes and mouth, and then compared against a set of template curves. The degree of similarity between input strokes and a template element defines the weights for a blendshape-based facial model. Shape and curve matching is performed using a combination of distance functions and similarity metrics, such as the Fréchet distance, modified Hausdorff distance and a simple Euclidean scheme. Our approach can be used for the fast-prototyping of facial expressions in production as well as educational

A Facial Sketch Animation Generator for Mobile Communication
The ability to analyze and reproduce specific-person facial expression is an important multimedia content service for mobile communication. In this paper, a novel three-layer facial animation model is presented for generating the personalized facial sketch animation, and the three layers are motion sequence layer, the reference shape layer, and the painting shape layer. Based on the model, a fa...
متن کاملSketch-Based Posing of 3D Faces for Facial Animation
This paper presents a novel approach to creating 3D facial animation using a sketch-based interface where the animation is generated by interpolating a sequence of sketched key poses. The user does not need any knowledge of the underlying mechanism used to create different expressions or facial poses, and no animation controls or parameters are directly manipulated. Instead, the user sketches t...
متن کاملPainting on Canvas: A Facial Sketching Control System
Facial Animation in films and videogames has traditionally relied on creating all the facial poses and animation controls in the early stages of a production. This process, whether for key framed controls or motion captured animation, takes a lot of time and effort. We present a novel sketching control system inspired in the way artists draw, where a stroke defines the shape of an object and re...
متن کاملSketch-Based Controllers for Blendshape Facial Animation
The blendshape approach is a widely used technique to generate realistic facial animation. However, creating blendshape facial animations using traditional weight editing tools requires either memorizing the function of a large number of parameters, or a trial-and-error search in a high-dimensional space. Direct manipulation interfaces address this problem, allowing the artist to directly move ...
متن کاملA Nonlinear Grayscale Morphological and Unsupervised method for Human Facial Synthesis Based on an Example Image
Human facial generation of example image is used as a requirement for biometric applications for the purpose of identifying individuals. In this paper, face generation consists of three main steps. In the first step, detection of significant lines and edges of the example image are carried out using nonlinear grayscale morphology. Then, hair areas are identified from the face of sample. The fin...
