This paper presents a real-time face detection algorithm for locating faces in images and videos. This algorithm finds not only the face regions, but also the precise locations of the facial components such as eyes and lips. The algorithm starts from the extraction of skin pixels based upon rules derived from a simple quadratic polynomial model.(More)
Computer graphics animation often lacks interaction between rigid object and granular material. In this paper, we propose a method for the deformation of the ground surface that consists of granular material when it penetrated by a rigid body object in motion. Meanwhile, the motion of the rigid object is also affected due to the collision with the ground(More)
Static gestures can convey certain meanings and act as specific transitions in dynamic gestures. Therefore, recognizing static gestures is one of the most important aspects of gesture recognition. In this paper, a new approach is presented for recognizing static gestures based on Zernike moments (ZMs) and pseudo-Zernike moments (PZMs). The binary hand(More)
Synthesizing transition textures on succession patterns for displaying visually acceptable terrain is essential to applications such as computer games. In this paper, we exploited the Game of Life model to simulate successions on terrain to show that a good-looking profile can appear quickly and easily. Based on the proposed modified patch-based sampling(More)
In this paper, we utilized Hidden Markov Model (HMM) as a mapping mechanism between two different kinds of correlated signals. Specifically, we developed a voice-driven talking head system by exploiting the physical relationships between the shape of the mouth and the sound that is produced. The proposed system can be easily trained and a talking head can(More)
