基于互相关模板匹配的matlab源代码，欢迎有需要的下载(Based on cross-correlation template matching matlab source code, welcome to the needs of downloads)

该程序涉及了M序列的生成，以及相关辨识法的基本实现和概念。(The procedure involves the M-sequence generation, as well as the basic realization of the identification method and concepts.)

本文主要讨论获得图片后如何提取其边界信息，首先利用图像灰度均匀化解决了对比度不清晰的问题，然后利用高斯滤波法对图片进行滤波去噪，进而利用Canny算法实现边缘检测提取边界，该方法与Matlab自带的求边界方法有明显的提高，为利用Matlab程序求图像分形维数提供了更精确的前提。(This article focuses on how to get the image to extract the boundary information, the first to use to the gray uniform solve the contrast is not clear, and then use the Gaussian filter image filtering noise, and then use the Canny edge detection algorithm to extract the boundary of the and Matlab comes boundary method has increased significantly, and provide a more accurate premise for the use of Matlab program for image fractal dimension.)
