将处理过的二进制比特流写入图像，保存显示 (The treated binary bit stream to write the image )

时隙 ALOHA（Slotted ALOHA）算法是在纯ALOHA 算的基础上将时间分成了多个离散的时隙，被分割成的时隙的长度要大于标签所携带数据信息帧的长度(Slot ALOHA (Slotted ALOHA) algorithm is based on pure ALOHA time will be counted into the slot more discrete, divided into the slot length is greater than the length of the data label information carried by the frame)

说明：  该程序加载组织样本的图像，计算其强度直方图并绘制。(This program loads an image of a tissue sample, calculates its intensity histogram and draws it.)

经典的图像处理常用图片，包括Lina，Barbana, Cameraman(Classic image processing commonly used pictures, including Lina, Barbana, Cameraman)

说明：  可以获取连通域的最小外接矩形，然后做些其他处理(You can get the minimum external rectangle of a connected domain,and you can do something else.)

为数字图像水印提供多种攻击方式，其中包括JPEG压缩、高斯低通滤波等多达十种攻击方式。(Offers a variety of attacks of digital watermarking ,including the jpeg compression, Gaussian low-pass filtering, up to ten different attacks)

说明：  一、课题介绍 本设计为基于MATLAB的火焰烟雾火灾检测系统。传统的采用颜色的方法，误识别大，局限性强。结合火焰是实时动态跳跃的，采用面积增长率，角点和圆形度三个维度相结合的方式判断是否有火焰。该设计测试对象为视频，通过下一帧和上一帧的差异发现是否有火情，并可发出语音报警。本设计带有一个人机交互式GUI界面，界面友好。是个不错的bishe选题。 二、算法流程 结合火焰的面积增长率，角点和圆形度三个维度综合判断。并且得出每帧图像火焰部分的该三个参数，实时显示在GUI上。 三、GUI界面设计(This design is based on MATLAB flame smoke fire detection system. The traditional method of using color has large error recognition and strong limitation. Considering that the flame is real-time and dynamic jumping, the area growth rate, corner and roundness are combined to determine whether there is flame. The test object of the design is video. Through the difference between the next frame and the previous frame, whether there is fire is found and the voice alarm can be sent out. This design has a personal computer interactive GUI interface, the interface is friendly. It's a good choice for BiShe.)

此文件是关于图像处理中灰度视频播放等相关知识的综合运用。(it is about the gray in image processing)

分别利用均值滤波、自适应滤波和中值滤波对噪声图像g1和g2进行滤波，利用峰值信噪比对去噪性能进行比较。(Respectively, using the mean filter, adaptive filtering and median filtering images g1 and g2 noise filtering, denoising performance comparison using the peak signal-to-noise ratio.)

图像球面化，对于输入的图片进行球面变换达到图形变形的效果(Spherical image of, for input images to spherical transformation to achieve the effect of graph distortion)
