DOE (2)
说明: 衍射光学光束整形元件设计
目标:在透镜后焦面上实现图形的光强分布
实现:
1、波长、衍射光学元件口径、形状、入射波前、二维目标分布及尺寸等都可自行设定;
2、对相位进行8台阶量化,重新计算;
3、更换输出面的采样间隔,重新计算。(Design of Diffraction Optical Beam Shaping Element
Objective: To realize the intensity distribution of the pattern on the focal plane behind the lens.
Realization:
1. Wavelength, aperture, shape, incident wavefront, two-dimensional target distribution and size of diffractive optical elements can be set by themselves.
2. The phase is quantized by 8 steps and recalculated.
3. Replace the sampling interval of the output surface and recalculate it.)

利用聚类技术实现纹理分割
说明: a)针对合成纹理图像(共有4 个合成纹理图像,见文件夹:
Texture_mosaic_data)中每一个像素提取纹理特征向量;
b)利用聚类技术(推荐用k‐均值聚类,可以从网上查找原码)对特征向
量空间中的点进行聚类,类别数可根据图像中的实际纹理类数确定。最后把类
属标签映射成图像形式显示(如下图,其中b、d、f、h 为相应的基准分割图像)。(A) for synthetic texture images (there are 4 synthetic texture images in total, see the folder:
Texture feature vector is extracted from every pixel in texture;
B) use clustering technology (K-means clustering is recommended, and the original code can be found on the Internet) to search the feature direction
The number of categories can be determined according to the actual number of texture classes in the image. Last class
The generic label is mapped to an image (as shown in the figure below, where B, D, F, h are the corresponding reference segmentation images).)
