In this paper, a facial sketch system based on real-time video is presented. This system automatically synthesizes facial edge sketch by tracking facial main control points (MCPs) accurately. There are four key steps in the system. First, dozens of main control points are obtained from frontal face image by Active Appearance Model (AAM). Second, when face moved or rotated, the new positions of MCPs...
An effective and fast face pose estimation method in video sequence has been proposed based on estimating the relative location of mouth in a face. Firstly, Faces are detected in the first several frames of video sequence. Then the detected face region is being tracked by the CAMShift (Continuously Adaptive Mean Shift) algorithm and an ellipse model is used to locate human face regions and angles...
This paper examines the performance of three different approaches in estimating the firm parameters of structure models by simulation, including the simultaneous equation system approach, maximum likelihood estimation approach and the iteration approach. The simulation results show that iteration approach has smaller estimation errors than the other two approaches and thus performs the best.
