文字可视化，对于给定的文本，输出可视化效果的程序。(word visualization)

说明：  2019最新的神经网络隐写分析网络，对空域频域均可(The newest neural network steganographic analysis network 2019 is applicable to both spatial and frequency domain)

说明：  matlab编写的直线检测算法，能够有效的提取出直线。和matlab自带的hough变换实现的同样的功能(matlab prepared in a straight line detection algorithm can effectively extract the straight line. And the hough transform matlab own to achieve the same function)

通过对图像进行逆透视变化，得到图像的俯视图，即鸟瞰图(Through the inverse perspective change of the image, we can get the top view of the image, that is aerial view.)

图像处理入门编程 包括动态跟踪和视频处理 有对应的任务指导书(image processing include the mission book)

说明：  实现图像处理中的白平衡调节问题， 可以帮助得到白平衡后的图像,内有帮助文档和实例图像(To achieve the white balance adjusted image processing problems, can help get the image after white balance, there are help files and examples of images)

说明：  用重心法实现光斑中心定位，matlab程序(Facula Center Location by the Method of Center of Gravity)

图像经过双随机处理和分数阶傅里叶变换，可以达到加密解密的功能，且对密钥敏感性较强。(The image undergoes double random processing and fractional Fourier transform, which can achieve the function of encryption and decryption, and has strong sensitivity to the key.)

Dijkstra’s算法的实现,还有具体的实验报告,欢迎下载()

对比BP，OMP，StOMP对自然图像的重构效果,输入图像是一幅256*256的lena图像，我们使用压缩采样后，再用上述三种方法对其进行重构，比较其结果，其中StOMP方法是用不同的阈值(Contrast to BP, OMP, StOMP effect on the reconstruction of natural images, input image is a 256* 256 lena image, we use the compressed sampled, and then reconstruct them the above-mentioned three methods to compare their results, which StOMP method is to use different thresholds)
