This paper presents a system for performance-driven avatar animation by estimating facial pose and expression parameters from single image. In this system, a 3D shape prediction model is trained based on local binary feature (LBF) algorithm, which use random forest to extract image features and learns a linear regression model mapping these features to 3D shape. With the help of this model, the 3D...
Among all the feature matching algorithms, SURF is famous for its computation efficiency in lots of practical applications. For recently popular stereoscopic videos, sparse feature matching, in which SURF is usually adopted, is the pre-processing of adjusting the 3D effect. However, significant improvement still can be made for SURF in stereo images. In this paper, a new two-layer feature descriptor...
Nowadays, with the rapid development of tereoscopic display technology, grating has been more and more widely used in auto stereoscopic 3DTV. This paper introduces a method that can be used to measure the parameters of lenticular-lens sheet for 3DLCD. This method is mainly based on the pure white-black characteristic image, by making use of the iterative method to get close to the accurate values...
The 2D to 3D conversion technique plays an important role in the development and promotion of three-dimensional television (3DTV), because it can provide adequate supply of high-quality 3D program content. This Paper focuses on the real-time implementation of 2D-3D system, of which the major parts are source depth-map generation and depth image-based rendering (DIBR). The depth-map is generated by...
