数字图像压缩方向一些经典压缩方法的matlab程序实现(Digital image compression direction, some classic compression methods, matlab program implementation)

本设计主要目的是实现染色体的识别计数。首先对图形进行预处理，将图像转化为灰度图、滤波去噪，然后对图像进行二值化，合理选取阈值，进行直方图阈值处理，最后去除图像中面积过小的杂点，最终实现识别计数。(The main purpose of this design is to achieve the identification of chromosome count. The graphical pre-processing, the image is converted to grayscale, filtering denoising, image binarization, reasonable selection of the threshold, histogram thresholding, and finally remove the image area is too small noise , and ultimately identify the count.)

一个基于内容的图像检索程序，用于相关反馈检索，采用自己研制（已发表）的查询点学习算法。(a content-based image retrieval procedure for relevance feedback retrieval, own research (published) inquiries point learning algorithm.)

基于对尺度的MSR算法的医学图像增强算法。 调试可以通过 对于低对比度的医学图像有很好的效果！(scale based on the MSR algorithm of medical image enhancement algorithms. Debugging through the low-contrast image has good results!)

matlab程序，利用主元分析、T2统计图和贡献率图方法对数据进行故障检测和诊断，贡献率图是变量对失控得分进行贡献率计算(matlab program, using principal component analysis, T2 charts and maps of the contribution rate of the data for fault detection and diagnosis, the contribution rate of the variable on the map is out of control scores calculated contribution rate)

超宽带雷达信号二维FFT求速度和距离，速度补偿后的算法(Ultra-wideband radar signal 2D FFT for speed and distance, speed compensated algorithm)

说明：  进行三维去高后，根据sar参数信息，将斜距转变为地距。(After performing three-dimensional height removal, the slope distance is converted to ground distance according to the sar parameter information.)

第二代离散曲波变换的源程序，包括图像处理中的应用(Second-generation discrete curvelet transform of the source, including the application of image processing)

SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点，其匹配能力较强，可以处理两幅图像之间发生平移、旋转、仿射变换情况下的匹配问题，甚至在某种程度上对任意角度拍摄的图像也具备较为稳定的特征匹配能力。该算法目前外文资料较多，但中文方面的介绍较少.(SIFT feature matching algorithm is at home and abroad feature points matching hot area of ​ ​ research and difficulties in its matching capability that can handle between the two images, translation, rotation, the matching problem in the case of affine transformation, and even to some extent have a relatively stable feature of the ability to match images taken on any angle. The algorithm is more foreign materials, but the Chinese introduction less.)
