摘　　要：研究单样本如何转化为普通模式识别问题,在平面范围内通过简单二维变换操作生成多张不同的虚拟图像,同时考虑三维空间内人脸姿态问题,在二维平面内映射三维运动,生成具有真实感的多姿态人脸图像。并分析了目前文献中相关方法存在的不足,在已有方法的基础上提出一种改进型异步旋转映射方法。实验结果表明,生成的图像具有姿态旋转、畸变率少、真实感好,且识别率较原方法得到了有效提高。The conversion of a special single sample problem into a general pattern recognition problem is stud- ied by generating several different virtual images using easy 2D transformation in the scope of the plane. The 3D space face pose problems are discussed by mapping 3D movement in 2D plane to generate vivid multi-pose face im- age. The shortages of the existing methods are analyzed and a modified asynchronous rotational mapping method on the basis of the original method is presented. The experimental results show that the generated images are more rotat- able and realistic with lower distortion rate and effectively improved recognition rate.
