▍1. 自由衍射
说明: 实现传统单透镜成像,这里有一步衍射,也有两步衍射。此外给出了相关书籍,仅供参考。(Realization of traditional single lens correlation imaging)
说明: lsb数字水印算法,SB算法利用了数字图像处理中位平面的原理,即改变图像的最低位的信息,对图像信息产生的影响非常小,人眼的视觉感知系统往往不能察觉。以一幅256灰度的图像为例, 256 灰度共需要8 个位来表示,但其中每一个位的作用是不一样的,越高位对图像的影响越大,反之越低的位影响越小,甚至不能感知。(Digital watermarking algorithm based on lsb)
说明: 在LS-SVM的基础上进行优化求解,速度更快更优。(On the basis of LS-SVM, the optimization solution is faster and better.)
说明: 本代码实现了K均值聚类,代码简单易懂,容易初学者学习(This code realizes K-means clustering, the code is easy to understand, easy for beginners to learn)
说明: 将原图二值化处理后,对二值图像进行腐蚀处理去掉图中主体以外的噪点或小斑迹(After binarization of the original image, the binary image is corroded to remove the noise or small spots outside the main body of the image)
说明: 用数字图像处理方法提取书法特征 实现书法骨架提取(Using digital image processing method to extract calligraphy features)
说明: k-means,DB-SCAN,基于密度峰值的聚类算法的matlab简单实践Clustering-matlab-master(k-means,DB-SCAN,Clustering-matlab-master of Simple practice of matlab based on density Peak clustering)
说明: 对图像格式进行更改,将mat格式转化为其它格式的程序(Program to change image format and convert mat format to other formats.)
说明: 二维原始Otsu算法的MATLAB实现和其对应的文献。实现效果很好。(MATLAB realization of two-dimensional original Otsu algorithm and its corresponding literature. To achieve good results.)
说明: 该算法实现了数字水印的嵌入与提取,然后对图像进行均衡化处理,分析均衡化处理后的图像对数字水印嵌入和提取效果的影响。(The algorithm realizes the embedding and extraction of digital watermark, and then carries on the equalization processing to the image, analyzes the influence of the equalization processed image on the embedding and extraction effect of digital watermark.)
说明: 处理在圆极化入射下的聚焦电场和相位。通过去除掉入射电场,把x,y,z分量的电场合成交叉极化的圆偏振电场,看到更好的聚焦效果(It deals with the focusing electric field and phase under circularly polarized incidence. By removing the incident electric field and synthesizing the X, y, z component electric field into the cross polarized circular polarized electric field, we can see the better focusing effect)
说明: 基于高斯金字塔建模技术,使用高斯金字塔背景建模法完成的目标检测与跟踪,代码调试既可以使用!(Based on gaussian pyramid modeling technology, using gaussian pyramid background modeling method to complete the target detection and tracking, code debugging can be used!)
说明: 基于MATLAB的行人检测。直接运行imhogtrace主程序,即可得到运行结果。针对不同的图像,需要调整参数,我放的这张图,虽然效果不好,但是可以提供参考意义(Pedestrian detection based on MATLAB. Run the main program of imhogtrace directly to get the running result. For different images, parameters need to be adjusted. Although the effect of this picture I put is not good, it can provide reference significance)
说明: 高斯混合背景建模MATLAB代码,用于背景提取,获得前景(Gaussian mixture background modeling MATLAB code for background extraction, to obtain the foreground)
说明: 非常经典的基于特征的影像匹配,亲测好用,推荐下载试试,基础但好用(Feature-based image matching)
