Abstract: PURPOSE: A method for detecting the movement of a face based on an optical flow and a recording medium thereof is provided to analyze the movement of the face in real time. CONSTITUTION: A method for detecting a movement of a face based on an optical flow comprises steps of dividing a face area and matching the face area to a three-dimensional mesh model, and changing the three-dimensional face model using an extracted motion parameter. In the method, the process for dividing the face area comprises steps of deciding a reference map by learning, dividing an image using the reference map, extracting a feature to remove a noise, and dividing the face area. The matching process comprises steps of extracting a feature point from an image, matching the feature point to a generic mesh model, and moving a node of the generic mesh model using a linear interpolation to perform a matching process of each portion. The optical flow is calculated by a differential way.

Abstract: PURPOSE: A facial expression method is provided to express more natural and realistic face look and automate a facial expression animation by using a spring mass damper model based on a physical property and a muscle model based on a parameter base model. CONSTITUTION: A facial expression method comprises steps of generating a polygonal face mesh model with a plurality of nodes and edges, assuming each edge as a spring by applying a spring-mass-damper model to a facial mesh model, obtaining a dynamic equation modeling a force transferred to an adjacent node via the edge, imposing a force to an arbitrary part of the facial mesh model according to a facial expression, and limiting a force transfer area when a force is transferred to an arbitrary part of the facial mesh model. If the force is imposed to the arbitrary part of the mesh model, the force is transferred to a limited area of the adjacent node according to the dynamic equation.
