基于matlab的钢筋计数方法，有ui界面(MATLAB-based steel bar counting method with UI interface)

本程序实现了对影像特征点自动提取，利用Morevac、Forstner、Harris3个经典算子。在此基础上利用相关系数法实现影像自动匹配，并且引入最小二乘平差，使匹配点精度有所提高。 在搜索点过程中，利用了核线影像特性，对二维影像搜索使用了爬山法启发式搜索。对大数据量影像采用影像金字塔结构处理。 1、使用GDAL库读取影片，支持TIFF、PNG、JPEG、JPG、BMP、GIF、IMG格式读取。使用GDI绘图。 2、防止大数据量绘图视图闪烁，图片显示采用双缓存技术。 3、保存视图数据为图片文件，支持TIFF、PNG、JPEG、JPG、BMP、GIF格式保存。 4、TreeCtrl控件、ListCtrl控件的基本操作。 5、MFC单文档程序视图通讯、更换视图、视图分割。(This program of image features automatic extraction point, use Morevac, Forstner, Harris3 a classic operator. Based on the correlation coefficient method using the image matching, realization and introducing least squares adjustment, the matching point to improve precision. In the search process, the use of the image characteristics of nuclear line, 2d image search using the heuristic method of climbing. For large quantity of data using image processing image pyramid structure. 1, using film, read GDAL repository support JPEG, TIFF, PNG, GIF, BMP, JPG, read IMG format. Use GDI drawing. 2 and prevent large amount of data, drawing view pictures showed adopt double caching techniques. 3, save for the image file, views data support JPEG, TIFF, JPG, PNG, GIF, BMP format. 4 and TreeCtrl controls, the basic operation ListCtrl controls. 5 and MFC single document procedure view communication, replace view, view.)

首先将RGB转换到HSV，再根据阈值进行HSV图像的分割(First convert RGB to HSV, then HSV image segmentation based on threshold)

说明：  “求RGB转HSI空间小程序.m”为主函数调用rgb2hsi.m，由于matlab没有自带这个函数，所以自编了一个，用于进行阴影去除。( Seeking RGB to HSI space program. M the main function call rgb2hsi.m, as a result of matlab does not own this function, so a self-compiled, used for shadow removal.)

对图像做spca有监督的主成分分析降维，并投影回图像来降噪，在本程序中，使用正弦函数控制图像变化，函数值作为监督信息(Image do spca supervised principal component analysis dimension reduction, noise reduction and projected back images)

说明：  对多帧图像进行超分辨率处理，得到一副高分辨率的单帧度图像。(Multi-frame image super-resolution processing, get a degree of high-resolution single-frame image.)

这是一个扫描线种子填充算法的程序，这个程序的演示效果不错(This is a scan line seed fill algorithm program, this program demonstrates good results)

说明：  matlab三维重建程序 完整的程序，入门相当不错，值得学习！(matlab program complete three-dimensional reconstruction process started quite well, it is worth learning!)

目标跟踪中常用到的阿尔法-贝塔滤波 有图有真相(Target Tracking commonly used to Alpha- Beta filtering map with the truth)

基于sift算法的图像拼接matlab代码，经过测试，可以运行，对有重叠部分的图像进行拼接，效果不错(Sift algorithm based on the image mosaic matlab code, the test run splicing with overlapping portion of the image, good results)
