最大灰度梯度清晰度评价函数

matlab例程，用于计算任意层数平板波导结构。其中slabexec为主程序，readme中有程序使用的详细说明。可以计算任意层数的平板波导结构的有效折射率，光场分布和远场分布。(matlab routines used to calculate the arbitrary layer slab waveguide structure. Which mainly slabexec procedures, readme has procedures used in detail. Can calculate the arbitrary layers of planar waveguide structure of the effective refractive index, optical field distribution and far-field distribution.)

SIFT，即尺度不变特征变换（Scale-invariant feature transform，SIFT），是用于图像处理领域的一种描述。这种描述具有尺度不变性，可在图像中检测出关键点，是一种局部特征描述子。[1] 该方法于1999年由David Lowe[2] 首先发表于计算机视觉国际会议（International Conference on Computer Vision，ICCV），2004年再次经David Lowe整理完善后发表于International journal of computer vision（IJCV）。截止2014年8月，该论文单篇被引次数达25000余次。(SIFT, namely Scale Invariant Feature Transform (Scale-invariant feature transform, SIFT), it is a description for image processing. This description has scale invariance, can detect critical point in the image, it is a local feature descriptor. [1] The method in 1999 by David Lowe [2] First published in the International Conference on Computer Vision (International Conference on Computer Vision, ICCV), 2004 was again perfect finishing after David Lowe published in the International journal of computer vision (IJCV) . As of August 2014, the paper cited the number of times a single article of more than 25,000 times.)
