实现对函数的步长加速法寻优，并作图直观显示寻优过程和效果(The step function to achieve acceleration method optimization and mapping visual display optimization process and effects)

说明：  顶帽变换的程序，能够实现平滑图像的效果。(Cap transformation process, to achieve the effect of smoothing the image.)

对数极坐标系，做图像配准和场景拼接的朋友应该可以用到(several polar coordinates, so image registration and stitching the scene should be applied to a friend)

说明：  snakes算法简单程序（可运行），对初步学习snakes算法有帮助(snakes simple algorithm (runs), the preliminary study snakes help Algorithm)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

通过使用MATLAB语言建立三维渐开线齿轮啮合模型(use MATLAB to draw 3-D gear)

说明：  通过设置5个不同的时域窗尺度和8个方向（theta），得到40个Gabor滤波器。但在滤波器显示的时候出现了问题。以下分别把程序的源代码、调用代码(Forty Gabor filters are obtained by setting 5 different time window scales and 8 directions (theta). But there was a problem when the filter was displayed. The following procedures are the source code, call code)

可以利用MATLAB编写GDSII图形文件，GDSII是一种时序提供格式，用于设计工具、计算机和掩膜制造商之间进行半导体物理制板的数据传输。得以普遍应用，成为半导体工业最常用的文件格式。在成为工业标准之前，GDSII最初始于GE Calma公司。GDSII格式对分布于每一个制作层的电路单元进行全面描述。这种格式是基于二进制的独立平台。电路单元可包含诸如多晶硅（两维域），连线和其他用于分级设计的单元件。(The program can be used to write GDSII format file. GDSII stream format, common acronym GDSII, is a database file format which is the de facto industry standard for data exchange of integrated circuit or IC layout artwork. It is a binary file format representing planar geometric shapes, text labels, and other information about the layout in hierarchical form. The data can be used to reconstruct all or part of the artwork to be used in sharing layouts, transferring artwork between different tools, or creating photomasks.)

光斑的中心提取：重心法和圆拟合。先用多次迭代求阈值并且对图像二值化，再用重心法和圆拟合提取光斑中心。(light spot method：median point ，circle fitting)

石墨烯的结构编程图,这是费了工作人员很长时间才完成的。(The figures of graphene)
