Face Animation Parameter Extraction in Real Video Environment

One of the challenging problems in machine vision and computer graphic is realistic face modeling and animation. Using markers on the face key points and tracking the movements of the markers is a low cost method to determine these parameters. Since MPEG4 standard has defined parameters for face modeling and animation, we place markers on the key points defined in MPEG-4 standard, and propose a system for accurate tracking of them. We examine the system in real movie capturing conditions. Various distortions such as change of lightening, Gaussian noise, blurring, compression, and temporal filtering are examined, and the system degradation in each case is reported.
