notchfilter

本代码可以实现图像的维纳滤波，经过调试无错误，对于学习图像处理有较好帮助。(This code can achieve the image filtering, error-free through the debugging, better for learning image processing help.)

说明：  多边形裁剪是逐次多边裁剪法，它的基本思想是以窗口的四条边界线单一逐次对多边形裁剪(polygon clipping is Successive multilateral cutting, its basic idea is a window four successive boundaries of a single polygon clipping)

高斯分布二维的数据的产生和画图函数，供数据仿真分析用(Two-dimensional Gaussian distribution of data generation and drawing functions, for simulation data analysis)

三维图像配准中的互信息程序。加入边界处理。(脠媒脦 卢 脥 录 脧帽脜盲 脳 录 脰脨渭脛 禄楼 脨脜脧 垄 鲁 脤脨貌 隆 拢 录 脫脠毛 卤 脽 陆 莽 )

对彩色图像进行小波融合，融合后图像在视觉上有了很大的改善。(Color images of wavelet fusion images visually a great improvement.)

说明：  使用openmv实现人脸识别。。。。。。。。。。。。。。。。。。(Face recognition is a kind of biometric technology based on facial feature information. A series of related technologies, also known as portrait recognition and face recognition, that use cameras or cameras to collect images or video streams containing faces, and automatically detect and track faces in the images, and then perform face recognition on the detected faces.)

用于脸部识别时，使用基于像素和区域的图像特征核的稀疏表示的识别算法。(When used in face recognition using image recognition algorithm based on feature pixel and regional nuclear sparse representation.)

剪切波是小波变换的一种，常用于增强或者去噪，本代码用于去除图像噪声(The shear wave is a wavelet transform, often used to enhance or de-noising, the code is used to remove the image noise)

对自适应双边滤波进行图像增强，使图像去噪效果更好(Adaptive bilateral filtering for image enhancement, image denoising effect is better)

说明：  采用 MATLAB 开发环 境，提出了一种图像信息隐藏算法，实现了图像信息隐藏的两大基本功能，即信息的嵌入和信息的提取．同 时，模拟常见的攻击方法，验证了添加隐藏信息后的图像的抗攻击能力(Using MATLAB to develop the environment, an image information hiding algorithm is proposed, which realizes two basic functions of image information hiding, i.e. information embedding and information extraction. At the same time, common attack methods are simulated to verify the anti-attack capability of the image added with hidden informati)
