特征提取是图像配准的重要步骤，使用Harris角点检测算法实现图像拼接。(Feature extraction is an important step in image registration, using Harris corner detection algorithm for image mosaic.)

需安装Halcon

ncc查询匹配的方法，可以用来做各种图像匹配的简单代码(ncc query matching method can be used for a variety of image matching short code.)

基于OpenCV实现的图像切割程序，通过程序中参数设置分块的数量和大小(The project is uesd to break an image into block)

图像识别，包括人脸识别和虹膜识别，在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置，先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心，该圆心只要能落在瞳孔内部即可。(Image recognition, including face recognition and iris recognition, iris position in the digital image of the iris recognition and effective positioning is the key issue. Using a model based on active contour method of positioning the iris position, the first gray projection method used to detect a point within the pupil as a pupil of the pseudo-center of a circle, the center of a circle can be as long as it falls within the pupil.)

IDL平台环境下，envi温度植被干旱指数计算TVDI(Calculation of envi temperature and Vegetation Drought Index under IDL platform TVDI)

有效地MR图像重建算法，主要用于在MR图像的成像过程中对图像进行压缩(Efficient MR Image Reconstruction for Compressed MR Imaging)

用matlab实现了分形，效果还是不错的，是分形学习中的基础内容(Matlab realize the use of fractal, the effect is still good, is a fractal study based on content)

心血管分割，多尺度， 对于中心点的位置有很强的鲁棒性(Edge forcing)
