本程序是一幅512*512的lena.raw图像进行快速DCT和其逆变换，整个程序均调试通过，是在C语言环境下编写的，在整个关于快速DCT的源码中，本代码可以说是集大成者，很值得一看。(This procedure is mainly of a float or double type of data, rounding, the float data can be positive or negative, can be, take the whole principle of rounding.)

scikit-image: Image processing in Python：Python编写的图像处理程序，可直接调用，是学习python图像处理的很好参考。(scikit-image: Image processing in Python：Image processing program written in Python, can be called directly, is to learn Python a good reference to the image processing.)

显示24位灰度图象，24位真彩色图像以及图像的转换(shows 24 gray-scale image, 24 true color images and image conversion)

说明：  图像配准，利用互信息进行图像配准，主要针对旋转和平移(Image registration using mutual information for image registration, the main response to rotation and translation)

说明：  本算法包括区域生长法和形态学后处理算法，功能实现了皮肤镜图像的病变区域分割，准确度很高，后处理算法对原图的影响很小；(This algorithm includes region growing method and morphological post-processing algorithm. It can segment the lesion area of dermoscopic image with high accuracy, and the post-processing algorithm has little influence on the original image.)

说明：  能实现图像的分割和识别,能够区分开近似颜色区域的影响(this code can perform image crop and recongition)

在频域下分析提取纹理特征的代码，希望对大家有用(In the frequency domain analysis of extracted texture features of the code, in the hope that useful)

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，学习非常值得(The interface graphics with input and output functions designed by GUI of MATLAB have strong visibility and worth learning.)

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.)
