The accuracy of 3D face registration algorithm greatly influences the effect of 3D face recognition. While a lot of efforts have been dedicated in developing automatic and accurate registration methods, these methods usually cannot be compared and evaluated on a fair basis because of the lack of a standard quantitative measurement. In this paper, we propose a practical quantitative analysis method...
A segmentation method based on texture gradient is proposed for the high resolution remote sensing images which have rich texture information. First, Nonsubsampled Contourlet Transform is used to extract texture features. Second, texture gradient is calculated, and then it is combined with the intensity gradient to get the final gradient. At last, the labeling watershed algorithm is used in segmentation...
In this paper, we present a novel parallel implementation of Active Shape Model (ASM) on GPU for massive facial feature extractions in video or image sequence. With the Compute Unified Device Architecture (CUDA)-enabled GPU, the acceleration is significant and reported a 48 times performance boost comparing to a CPU implementation. We adopt the hardware built-in bilinear interpolation of texture to...
Realistic facial animation is important in many graphics applications, like animated feature films and computer games, to enrich human computer interaction. In this paper, we propose a physically-based facial animation approach employing knowledge from the anatomy and biomechanics of human facial muscles. First, the 3D face mesh is generated automatically by commercial software and the facial skin...
In this paper, we apply the compute unified device architecture (CUDA) to the 3D cone-beam CT reconstruction using simultaneous algebraic reconstruction technique (SART). With the hardware acceleration, the computationally complex SART can run at speed comparable to the commonly used filtered back-projection, and provide even better quality volume with less samples. The main contributions include...
