We present a method that combines performance-driven method with segmented 3D blendshape models to animate a face.First we prepare key sample examples and corresponding key target examples.Next we segment the whole face into two regions,for each region

以XRS-152/153影像增强器DR/CT成像系统为研究对象,在分析其输出像场畸变特性的基础上,从校正精度和校正实时性要求出发,采用空间坐标多项式变换方法进行畸变校正.同时,为了解决畸变校正算法计算量大、运算速度慢的问题,利用可编程图形处理单元(GPU,Graphic Processing Unit)并行计算和高速浮点计算特性,将图像映射为GPU中的纹理,采用多线程并行计算,使得校正算法在GPU
同一目标在不同观察视点下成像后外形可能有较大差异,因此三维目标多视点视图建模是目标识别的关键.针对该问题,提出了基于支持向量数据描述(SVDD,SupportVector Data Description)方法对目标特征进行描述.在视点球面上均匀采样获取目标全姿态图像,以SVDD方法求取在高维空间内包含尽可能多目标特征向量的最小超球体相关参数,得到数量较少的支持向量将作为目标多视点视图的最佳模型.
