The projection methods are currently among the most popular methods for solving viscous incompressible flow based on the primitive variable formulations.
目前，在计算非定常不可压缩流动的原始变量形式的数值方法中，投影方法得到了越来越广泛的应用。

The texture features such as direction and contrast of the image can be obtained from weighted projection statistics of primitive feature, which are more matched with human vision.
