Gamma-correction

说明：  利用matlab对多光谱遥感影像进行水体指数（ndwi）以及植被指数（ndvi）提取(Extraction of Water body Index (ndwi) and vegetation Index (ndvi) from Multispectral remote Sensing Images by matlab)

基于LSB的数字水印，有图像有源码，还有各种攻击(LSB-based watermarking, there is a source image, as well as a variety of attacks)

空间金字塔，通过对图片不断的进行层次划分，对每一层的图片信息进行整理用于图片分类等(Beyond Bags of Features: Spatial Pyramid Matching for Recognizing Natural Scene Categories )

本文介绍了一种 )’’ 多系统静态基线数据处理方法!该方法使用统一的方式来处理 &’ 5.)6’’ 北斗 及三者融合的观测数据#这种处理方法已经实现在广州南方测绘仪器有限公司的静态后处理软件中#本文使用实际数据验 证了这种处理方法!得到了较好的结果(This article describes a ) ' multi-system static baseline data processing method! This method uses a unified way to deal & ' ' 5.) 6' ' ' Compass and three observational data fusion# This treatment method It has been achieved in the static Guangzhou South mapping Instrument Co.# post-processing software used herein, the actual data validation of this approach!

说明：  通过比较在预处理中选择了灰度变换增强、选择了中值滤波平滑、Sobel算子锐化并利用Ostu法阈值分割法进行分割；用了小波多尺度检测进行检测，最后计算出大桥裂缝的相关数据，在大桥桥梁裂缝检测方法与研究中可以较好的实现大桥桥梁裂缝图像的检测。(the gray-scale transform enhancement, median filter smoothing, Sobel operator sharpening are selected in the preprocessing, and the Ostu threshold segmentation method is used for segmentation; finally, the wavelet multi-scale detection is used for detection, which can better realize the detection of the bridge surface crack image in the bridge surface crack detection method and research.)

说明：  利用python写的简单降噪程序（根据一个点A的RGB值，与周围的8个点的RBG值比较，设定一个值N（0

说明：  用于相位恢复基于FRENUP,LALALALLALA(FRENUP-based Phase Recovery)

Opencv处理图像，用ostu法实现图像的二值化(Opencv image processing, using ostu method to achieve image binarization)

人脸检测,是采用国外的一个论文中的算法实现，如果想要论文，请发信给我(face detecting)
