区域生长法获取图像边界 必须有种子 可以有很多方法 这里直接鼠标点击(Region growing method to obtain the image the border must have a lot of methods of seed can have a direct mouse click here)

该matlab代码实现了plsa算法。plsa全称是概率隐语义分析，是一个非常重要的隐语义分析模型。(This matlab code implements plsa algorithm, which is the short of probability latent semantic analysis and is a very important latent semantic analysis model.)

共厄梯度方法!!!本程序适用于求解形如f(x)=1/2*x Ax+bx+c二次函数的稳定点； (total Eritrea gradient method! ! ! The procedure will be applicable to solve the shape of f (x) = 1/2* x Ax bx c quadratic Function stability;)

彩色图像的DWT变换及水印提取，可以成功实现(Color image DWT watermark embedding and extraction (attack))

加入乘性噪声和椒盐噪声的图像进行维纳滤波和均值滤波，采用不同窗口看效果(Add the image of multiplicative noise and salt and pepper noise for Wiener filtering and mean filtering, using different windows to see the effect)

说明：  WAV音频的MATLAB读取以及傅里叶变换作频谱图(WAV Audio Reading by MATLAB)

图像边缘提取，边缘整合，有效提取边缘，并进行填充。(Image edge detection, edge integration, effective edge extraction and filling.)

SIFT特征是图像的局部特征，其对旋转、尺度缩放、亮度变化保持不变性，对视角变化、仿射变换、噪声也保持一定程度的稳定性，亲身检测可用(SIFT feature is a local feature of image. It keeps invariant to rotation, scaling, brightness change, and also keeps a certain degree of stability to view angle change, affine transformation and noise.)

8邻域边缘连接，实现闭合边界跟踪，简单实用(8 neighborhood edge connector, to achieve closure boundary tracking, simple and practical)
