本程序采用迎风方案实现推广GAC模型的水平集方法，希望大家借鉴。(This procedure uses the wind to promote GAC model programs to achieve the level set, and I hope everybody' s reference.)

使用regionprops中BoundingBox功能对图片进行处理获得X,Y的坐标值以及长宽度(Use regionprops the BoundingBox of the image processing functions to obtain X, Y coordinate values and long-width)

LBP（局部二值模式）特征提取，用于人脸识别，(LBP feature extraction for face recognition. . .)

使用区域生长法对灰度图像进行分割，显示原图及分割后的图像(Region growing method using gray-scale image segmentation, image display artwork and divided)

包含实验图片，实验代码,对于从事数字图像处理工作有一定帮助(including experimental images and agrithms.It is benificial to image procecing workers.)

Finding MSER regions and Canny edges in natural images

说明：  BMD完整代码，包括灰度图片和彩色图片的去噪、去模糊等功能，去噪效果尤为突出。(Complete code of BMD, including de-noising and de-blurring functions of gray image and color image, especially outstanding de-noising effect.)

A flexible way to capture the image, the main can capture the entire screen, active window, selected regions, fixed region, the selected control, the selected menu, select Web pages, images, various output methods, mainly including documents, clipboard, drawing and printers. Software has to capture the cursor, set the delay before the capture, display screen magnifier, custom capture hotkeys, image file names automatically by time or templates to capture the success of the voice prompts, repeat last capture, preview captured pictures, image print, image cut , the image to the color, the anti-color images, image flip, image rotation, image size setting, commonly used photo editing, wallpaper settings and other functions. Images can be captured to save the image file, copy to the clipboard, export to the drawing, print to a printer output of a variety of ways)

从回波中估计多普勒参数是合成孔径雷达运动补偿的关键。文中研究了多目标回波对参数估计的影响，从理论上推导了估计多普勒中心和调频率对回波的不同要求，并用两个指标举例分析了一段实测机载SAR数据，给出了实际应用中参数估计时选择回波的原则。(Doppler parameters estimation from radar echoes is a key step in SAR(Synthetic Aperture Radar}motion cornpensation． This paper researched the efect of multiple targets echoes to estimate parameters and deducted theoretically the different requirement for echoes in estimating doppler centroid and doppler frequency modulation rate．Th en giving a real airborne SAR echo as example，we analyzed it with two measurements and concluded the principle about choosing echoes in practice．)
