At first, the authors propose an adjacent pixel gray order-preserving principle. Adjacent pixel gray order-preserving principle is the basement of local enhancement method which ensures that there is no distortion in processed image. And then, the authors propose an iterative algorithm, which could stretch gray-scale difference of adjacent pixels in premise of not changing gray magnitude relationship between adjacent pixels. At last, the authors propose a totally reference image quality assessment method based on adjacent pixel gray order-preserving principle. According to this quality assessment method, the authors made a set of comparative experiments with local histogram equalization and method. Experimental results show that the proposed enhancement method can get higher score and provide better visual effects, fully demonstrating its effectiveness. According to this quality assessment method, the proposed method shows a good effectiveness, through experimental results and comparison with local histogram equalization method.   A higher order compact finite difference algorithm for solving the incompressible Navier-Stokes equations 期刊论文  OAI收割 International Journal for Numerical Methods in Engineering, 2011, 卷号: 88, 期号: 6, 页码: 511-532 作者:  Tian ZF;  Liang X(梁贤);  Yu PX 收藏  |  浏览/下载：45/0  |  提交时间：2012/04/01 Navier-Stokes Equations  Higher Order  Compact Finite Difference  Primitive Variable  Projection Method  Spectral-Projection Method  Numerical-Solution  Flow Calculations  Cavity Flow  Scheme  4Th-Order  Formulation
