里面包含了步态识别的整一套流程的代码实现，包括从视频流里面提取图片帧，背景建模，提取运动目标（运动检测），形态学处理（膨胀与腐蚀，连通性检测），归一化大小，步态能量图的构建，主成分分析（PCA）降维,线性判别分析（LDA）分类等等功能的代码实现。均通过测试。-Contains the gait recognition of the whole process of a set of code, including the extraction and picture frames from the video stream, and background modeling, extract the moving object (motion detection), morphology processing (expansion and corrosion, connectivity), normalized size, gait energy diagram construction, principal component analysis (PCA) dimensionality reduction and linear discriminant analysis (LDA) classification code implementation and so on functions. All pass the test.
