Method of generating feature vector, generating histogram, and learning classifier for recognition of behavior
Abstract:
Example embodiments disclose a method of generating a feature vector, a method of generating a histogram, a learning unit classifier, a recognition apparatus, and a detection apparatus, in which a feature point is detected from an input image based on a dominant direction analysis of a gradient distribution, and a feature vector corresponding to the detected feature point is generated.
Abstract(Chinese):

示例性实施例公开了一种生成特征向量的方法，生成直方图的方法，学习单元分类器，识别装置和检测装置，其中基于主导方向分析从输入图像检测特征点 生成与检测出的特征点对应的梯度分布和特征向量。
