Sketch

说明：  根据论文the missing memory found仿真生成v-i图像(Generate V-I image according to the missing memory found)

Prewitte边缘算子法(Prewitte Edge Operators)

说明：  根据粒径尺寸和数量生成随机骨料，添加钢纤维及聚丙烯纤维(Generate random aggregate)

说明：  在图像上画一条线，提取所在位置的像素。主要是用来观察横向异质性变化的。(Draw a line on the image and extract the pixels at the location. Mainly used to observe changes in lateral heterogeneity.)

连续信号的采样与重构,主要说明信号采样与重构程序(Continuous signal sampling and reconstruction, mainly explain the procedure of signal sampling and reconstruction)

自己写的均匀圆阵，矩形阵的方向图 画法。大家共享！(himself wrote of a uniform circular array, the array of rectangular picture in the direction of France. Share!)

实现SIFT特征点的检测及图像拼接功能，主要在原来作者的基础上添加了显示全部特征点或者只显示重叠区域特征点，能够直接使用(Achieve SIFT feature point detection and image stitching function, mainly on the basis of the original author to add a point or show all the characteristics of overlap only feature points can be used directly)

说明：  该程序SSIM（结构相似度）是基于matlab平台，用于图像的客观质量评价，是FR中精典算法(The program SSIM (structural similarity) is based on matlab platform for an objective image quality evaluation, is in the classical algorithm FR)

说明：  混合高斯背景建模，利用该方法建立动态视频中运动背景建模，得到较好效果(mixture of gaussian)

说明：  hough变换提取直线的程度，有详细注解，适合新人。(hough transform to extract linear extent, with detailed notes, for newcomers.)
