为了快速精确地对一个实体进行的三维重建, 提出了一种新的混合建模方法. 该方法利用同一实体在不同视 点下的多幅深度图像, 根据它们之间颜色和纹理的相关性, 通过逆投影变换, 可将图像中象素点映射到三维空间中的正 确位置. 然后再经模型重建和重投影, 可获取实体在任意视点下的图像. 实验结果表明, 这种建模方法具有复杂度恒定、 获取图像真实感强等优点, 适用于形状、 结构复杂的物体的重建.-: In o rder to reconst ruct th ree di mensi on model of an object, a new method of hybr id modeling is p resented . Th is method use mut i p le range i mage of different viewpo int, acco rding to the co lo r and texture, the p ixel po int can be mapped to co r rect po sit i on in th ree di mensi on space by the backp ro ject t ransfo rmat i on. Then the i mage can be go t in any viewpo int by modeling reconst ruct i on and rep ro ject i on. Exper i ments has p roved that th is method can acquire h igh realist ic i mage and has stat ic comp lexit i on. It can be used to reconst ruct some objects w ith comp licated shape and topo logies

利用决策导向无环图的算法，通过PCA进行了降维处理。为了看出不同核函数参数对识别率及运行时间的影响，我们采用了相同的惩罚因子而使用了线性核、二次核、多项式核、rbf核、多层感知器等核函数对这些数字样本进行分类，并对分类结果准确率及分类时间进行输出对比。
