说明：  LBP算法实现图像的纹理分类，基于论文：multiresolution gray scale and rotation invariant texture classification with location binary patterns(LBP algorithm to achieve image texture classification, based on the paper: Multiresolution gray scale and rotation variant texture classification with location binary patterns)

This is a Scaling function definition Image cutoff ratio for H = 3

说明：  本部分源码是处理静态图像时候，需要的一部分代码，希望对于那些正在研究图像处理技术的朋友有用。(This section is the source when dealing with a static image, the need for part of the code, I hope for those who are studying image processing technology useful friends.)

说明：  使用python语言编写卷积神经网络的卷积结构。(The convolution structure of convolution neural network is written in Python language.)

说明：  SIFT特征点的提取和匹配，SIFT算法首先在尺度空间上进行关键点检测，确定关键点的位置和关键点所处的尺度，然后使用关键点邻域梯度的主方向作为该点的方向特征，最后由关键点邻域梯度信息生成关键点的特征向量(SIFT algorithm firstly detects the key points in the scale space, determines the location of the key points and the scale of the key points, then uses the main direction of the key point neighborhood gradient as the direction feature of the point, and finally generates the feature vector of the key points from the key point neighborhood gradient information)

局部拉普拉斯滤波代码，效果很好，可以直接运行(Edge-aware Image Processing with a Laplacian Pyramid)

针对FCM算法的运行时间长和计算量大的问题，提出了改进的FCM算法，先将图像分割成窗口大小的子块，然后以子块为单位提取特征向量，用FCM聚类粗分割，然后对边缘子块，以像素为单位从新提取特征向量，进行细分割。分割后的结果提高了运行速度和分割精度。(For the FCM algorithm and the calculation of long run the problem of large proposed improved FCM algorithm, first image into blocks the size of the window, and then sub-block feature vector extraction unit, using FCM clustering coarse partition, and then block on the edge, in pixels from the new Feature Extraction, for fine segmentation. Improve the segmentation results after the speed and accuracy of segmentation.)

使用HIO算法实图像现相位恢复，包含源代码，简单实用。(HIO algorithm real image phase recovery, including source code, simple and practical.)

注意机制，显著图提取，使用PCA算法！效果理想。(Attention mechanism, saliency map extraction, using PCA algorithm! Effect ideal.)
