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.)

说明：  本程序功能为图像平滑的实现，平滑方法包括中值滤波、均值滤波和高斯滤波算法。可直接下载运行。(The program features for the realization of image smoothing。 The smoothing methods include median filtering, average filtering and Gaussian filtering algorithm. This program can be run directly after downloading.)

本程序为基于快速双边滤波器的边缘保持算法，算法具有平移不变性，具有线性复杂度(this is a edge-preserving denoising method using fast bilateral filter)

该文件包含高斯高通滤波的源代码和高斯低通滤波的源代码，可以运行，效果很好(Gaussian high-pass filter Gaussian low-pass filtering )

圆心检测算法，使用matlab根据sci文章仿写，在图像质量不高的情况下检测效率较高。(Center of a circle detection algorithm, the use of matlab under the sci article仿写, image quality is not high in the case of a higher detection efficiency.)

光流法，经典的LKPR-marzat算法，适合研究光流法的学者使用，可执行，无错误 (Optical flow method, the classic LKPR-marzat algorithm, for research scholars to use optical flow method, executable, error-free)

通过用户给定的标签信息，来提取图像中的标记像素点位置，保存为种子点(Through the label information given by the user, the position of the label pixels in the image is extracted and saved as seed points.)

灰度共生矩阵、灰度梯度共生矩阵提取纹理特征(Gray Level Co-occurrence matrices, gray-gradient co-occurrence matrix texture features extracted)

一种区域生长算法，用于图像分割。自动选择种子点。(A Region Growth Algorithm for Image Segmentation)
