One of the challenging problems in machine vision and computer graphic is realistic face modeling and animation. MPEG4 standard has defined parameters for face modeling and animation. We placed markers on the key points defined in MPEG-4 standard, and proposed a system for accurate tracking of them. We examine the system in real movie capturing […]
An important technique in image and video processing is global motion estimation (GME). The common GME methods can be classified in direct and indirect categories. Whereas the direct global motion estimation techniques boast reasonable precision they tend to suffer from high complexity. As with indirect methods, though presenting lower complexity they mostly exhibit lower accuracy […]
