matlab代码 用于遥感图像变化检测

说明：  此算法使用于单波段或者多波段图像中的非监督异常检测，性能很好~(The algorithm used in single-band or multi-band image unsupervised anomaly detection, performance very good ~)

利用Hough变换，可以检测图像中的多条线段，效果很好(using hough transform for line detection)

实现图像文件（如bmp等）的读取、显示、真彩图转换成灰度图、灰度图转化为二值图及绘制图像直方图功能。(Achieve an image file (such as bmp, etc.) to read, display, true color conversion to grayscale, converted to grayscale and binary image histogram function to draw the image.)

医学图像配准，医学图像2D_3D配准，基于vc++开发。(The registration of pre-operative volumetric datasets to intra-operative two-dimensional images provides an im- provedway of verifying patient positionandmedical instru- ment location. In applications from orthopedics to neuro- surgery, it has a great value in maintaining up-to-date in- formation about changes due to intervention. We propose a mutual information-based registration algorithm which es- tablishes the proper alignment via a stochastic gradient as- centstrategy. Ourmaincontributionliesinestimatingprob- ability density measures of image intensities with a sparse histogrammingmethodwhichcouldlead to potentialspeed- up over existing registration procedures and deriving the gradient estimates required by the maximization procedure. Experimental results are presented on fluoroscopy and CT datasets of a real skull, and on a CT-derived dataset of a real skull, a plastic skull and a plastic lumbar spine seg- ment.)

C标准函数源码，十分丰富，便于移植和裁剪。(C standard function source code, is very rich, easy to transplant and tailoring.)

一些阈值图像分割算法：迭代法；局部阈值；otsu；最大熵法等 (Some threshold image segmentation algorithm: the iterative method local threshold otsu maximum entropy method)

改进后的非线性各向异性扩散用于图像中的保边去噪，增加了二阶导数，是滤波效果更好(Improved nonlinear anisotropic diffusion for edge preserving image denoising, an increase of second derivative, is a better filtering effect)

daisy是08年新提出来的特征描述符算法，常用在图像匹配等领域中。文件包含算法的PDF文档和算法提出者编写的相应matlab程序，大家可以根据自己的需要来利用。(A Fast Local Descriptor for Dense Matching，2008.)

利用图像差分，进行人体跟踪，并记录视频帧中目标的坐标，（PS:没有上传视频模板）(Differential use of image for the human body tracking, and record the video frame in the coordinates of the target, (PS: do not upload videos template))

遥感图像配准，手动选取配准点。包括程序和原图像，待配准图像。(Remote sensing image registration, and manually select with punctuality.)
