FBG_filter

说明：  calibration摄像机镜头的校正程序(calibration Calibration camera lens calibration procedure)

基于图像检索的matlab代码，基于内容的图像检索中的一些关键环节：特征提取：颜色直方图；纹理特征等 相似度：马氏距离，欧氏距离等 相关反馈：机器学习方法，如SVM，神经网络等 检索与分类：两个很相似的样本距离很小，虽然两个不相似的样本距离未必很大(content-based image retrieval of some of the key issues : Feature Extraction : color histogram Texture characteristics of similarity : Mahalanobis distance, the Euclidean distance relevance feedback : machine learning methods, such as SVM. Neural network search and classification : two very similar samples from the small, although the two are similar to the samples may not be much distance)

主要用于标签文字的识别，效果比较好，实用性较强(Mainly used for the identification of the label text, the effect is better, more practical)

说明：  实现matlab对感兴趣区域（ROI）提取(Implement MATLAB to extract ROI)

显示不同类型的色表，并查找相应区域或位置的值。 基于idl编程 (Show the different types of color tables, and find the corresponding value of the region or location. Idl-based programming)

说明：  Arnold 变换与 Gray 码变换相融合的双置乱算法程序，包括了加密和解密程序(The program of double scrambling algorithm combining Arnold transform and gray code transform, including encryption and decryption program)

matlab环境下的，基于图像颜色特征的图像检索源代码(matlab environment, the color characteristics of image-based image retrieval source code)

距离多普勒成像算法，包含运动补偿距离徙动回波构造距离压缩方位压缩(Distance Doppler imaging algorithm, including motion compensation distance migration echo structure compression compression azimuth compression)

小波图像去噪，全局阈值法，是多阈值小波去噪中两大部分：全局阈值法玉局部阈值法的重要组成部分。(Wavelet denoising, the global threshold method, the multi-threshold wavelet de-noising of two parts: the global threshold method jade local threshold an important part of the law.)

说明：  利用Em算法进行图像分割的代码，可以运行，代码简短清晰，有利于初学者，希望对你有用(Em algorithm using image segmentation code, you can run, code clear brief will help beginners, in the hope that useful to you)
