用matlab编写的图像反转程序，编写的目的主要是为模式识别整理样本而用，希望对大家有帮助。(Prepared using matlab image reversal process, the preparation of the main objective is to order samples and to use pattern recognition, in the hope you help.)

完整的matlab程序实现数字下变频，ddc_out为主程序。内有详细的注释，易懂。(Complete matlab program digital down conversion. ddc_out is the main program. There are detailed notes, and easy to understand. )

matlab入门教程，主要介绍了基本运算与函数，流程控制，环境设置及二维画图等。(matlab Getting Started tutorial introduces the basic operations and functions, process control, environmental settings, and two-dimensional drawing and so on.)

很方便的Gabor滤波器做图像纹理方向检测(texture oriantation detection using Gabor filter)

说明：  用于估计未知数据的EM算法，即最大期望算法，用到的地方很多，可用来做同步。(The data used to estimate the unknown EM algorithm, that is the maximum expectation algorithm, used in many places, can be used for synchronization.)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)
