这是一个简单的演示如何评价文本的数学表达式
This a simple demo of how to evaluate mathematical expressions in text
format, including provision for variables and functions. The code consists of
three simple classes: 1) Calc - which does the main calculations, 2) Stack -
which is used to push and pop intermediate operators and numbers and 3)
Symbol Table. The symbol table is a collection of calc symbols, a type structure
consisting of various elements, including the expression name, function name,
and the final value of the expression The evaluation procedure is done in three
steps: 1) simplify the expression by removing all the elements within () and
storing them in subexpressions within the symbol table. 2) Each of these sub
expressions are then converted to RPN format (Reverse polar notation) and
evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text
format, including provision for variables and functi

香港城市大学改进的图像去雾算法
图像去雾雾，包括雾、霾、沙尘、烟等一切导致视觉效果受限的物理现象。由于雾的存在，户外图像质量降低，如果不处理，往往满足不了相关研究、应用的的要求。在雾的影响下，经过物体表面的光被大气中的颗粒物吸收和反射，导致获取的图像质量差，细节模糊、色彩暗淡。通过一定的技术手段，去掉物体表面的雾霭，增强图片效果显得尤为重要。 Tarel等人提出了一种基于中值滤波的去雾算法，该算法虽然速度比较快，但由于中值滤波不能很好的保持边缘信息，导致得到的大气散射光分布不能很好地反映场景的深度信息。在景深发生突变的边缘区域，无法得到令人满意的去雾效果。 在本篇论文中，香港城市大学针对Tarel去雾方法进行改进。 源码包来自作者的英文主页下载，其中包括作者EI论文原文，PPT，以及全部代码和测试集。对图像去雾领域的研究能提供重要的借鉴意义。
