现有的代数特征的抽取方法绝大多数采用一维的方法,即首先将图像转换为一维向量,再用主分量分析(PCA),Fisher线性鉴别分析(LDA),Fisherfaces式核主分量分析(KPCA)等方法抽取特征,然后用适合的分类器分类。针对一维方法维数过高,计算量大,协方差矩阵常常是奇异矩阵等不足,提出了二维的图像特征抽取方法,计算量小,协方差矩阵一般是可逆的,且识别率较高。(existing algebra feature extraction method using a majority of the peacekeepers, First images will be converted into one-dimensional vector, and then principal component analysis (PCA), Fisher Linear Discriminant Analysis (LDA), Fisherfaces audits principal component analysis (KPCA), and other selected characteristics, then use the appropriate classification for classification. Victoria against an excessive dimension method, calculation, covariance matrix is often inadequate singular matrix, a two-dimensional image feature extraction method, a small amount of covariance matrix is usually reversible, and the recognition rate higher.)

elevator_matlab
某居民楼共21层,从6:00到9:00,平均有500人出,200人进门,没有人楼层之间窜门,电梯运动通过
一层距离时间为1秒,启动和制动另需1秒,开门关门需要2秒,一个人进出电梯平均时间0。5秒,电梯容量
为15人,呼叫间隔服从指数分布,楼层等概率,上行将乘客送完,下行时有更低楼层呼叫(只要时间允许)就
带走,6:00时电梯在一楼,无乘客停在刚才服务的楼层,一般先先呼叫谁先接受服务,但上行时不接受更低呼叫
下行时不考虑更高楼层呼叫
