用于快速分类，图像，人脸识别，等，在机器学习，人工只能，数据挖掘领域有较多的使用。-for rapid classification of images, face recognition, etc., in machine learning, artificial only. Data mining areas with more use.

在基于特征提取方法之上, 研究用算法对目标多视角问题进行分类器设计。在对 图像进行独立成分分析后, 针对多姿态角目标识别问题, 提出了角度优先粗分类的设计方法-Feature extraction method based on above research objective of the algorithm to classify multi-view design problem. In the right image independent component analysis, t
