利用脉冲耦合神经网络（pcnn）实现图像滤波的源程序，已经过测试。(Using pulse coupled neural networks (pcnn) the realization of the source image filtering, has been tested.)

粒子群算法的Pareto多目标函数优化，适用于多目标问题的寻优(Particle swarm optimization Pareto multi-objective function optimization, suitable for multi-objective optimization.)

根据RBM深度网络（Hinton，2006）进行MINST手写文字的分类器的训练，利用训练得到的权值制作了这个小程序，通过这个程序可以看出训练结果对数据集内的测试样本和训练样本都能进行很好的识别，但是对其他的手写字体识别就没有那么好了。(According to RBM depth network (Hinton, 2006) conducted MINST handwritten text classifier training, using the training to get the right value to produce this small program, this program can be seen through the results of the training data set and the training sample test samples are can be well identified, but on the other handwriting recognition is not so good.)

人脸图像配准，将同一场景的两幅或多幅图像进行对准，可以实现人脸归一化(Face image registration, the same scene two or more images for the alignment can be achieved face normalization)

图像抠图是将图像的目标物体从背景图像分割出来的技术，这段代码是用MATLAB实现的一段抠图的代码(Image matting is the image of the target object from the background image segmentation techniques, this code is implemented using MATLAB code section of matting)

本程序用于数字水印，可以输入一副图像，嵌入水印信息，然后防止各种各样的攻击，最后可以提取水印信息，恢复原图像(This procedure for digital watermarks, can enter a pair of images, embedded watermark information, and then to prevent the various attacks, the watermark information can be extracted Finally, restore the original image)

VMD分解阈值去噪，进行极优模态分量的选择(VMD decomposition threshold denoising, selection of very excellent modal components.)

说明：  很不错的SVM的MATLAB源码，不用设置路径，比libsvm还好用！(SVM is a good source of MATLAB, do not set up the path, than to use libsvm better!)

在最不重要位替换嵌入算法的基础上引入矩阵编码，增强水印隐蔽性，有效地提高水印嵌入效率。(On the basis of the least significant bit embedded algorithm is introduced to Replace the matrix coding, to enhance hidden watermark, the watermark embedding effectively improve efficiency.)

说明：  利用遗传算法求多项式的最值,jiandande xy uexiGA(GA optimization)
