测量航测技术规划书 已通过审核，可供航测飞行技术设计参考(Aerial measurement technology planning book has been reviewed for technical design reference aerial flying)

说明：  标注节点距离，批量标注节点距离。节省画图时间 提高画图效率(Marking Node Distance)

数字图像处理试验程序 包括图像的压缩 模糊 锐化(Digital image processing, testing procedures, including image compression blur sharpening)

JPEG2000matlab实现 最新的图像压缩标准(JPEG2000matlab achieve the latest image compression standard)

基于DMRS和CP的频偏估计算法仿真，算法的CDF曲线(Simulation of frequency offset estimation algorithm based on DMRS and CP)

图像经过双随机处理和分数阶傅里叶变换，可以达到加密解密的功能，且对密钥敏感性较强。(The image undergoes double random processing and fractional Fourier transform, which can achieve the function of encryption and decryption, and has strong sensitivity to the key.)

说明：  将原图二值化处理后，对二值图像进行腐蚀处理去掉图中主体以外的噪点或小斑迹(After binarization of the original image, the binary image is corroded to remove the noise or small spots outside the main body of the image)

图像分割方法，可以自动获取目标图像的边界，并且可以有效分割灰度不均匀图像(The level set segmentation method can automatically obtain the boundary of the target image, and can effectively segment inhomogeneity image.)

均值偏移算法，在图象的平滑和分割方面是一种很有用的处理方法(mean deviation algorithm, the image smoothing and segmentation is a very useful approach)

实现对图像的任意形状的裁剪。注意：图像裁剪后带有背景色(Realization of arbitrary shape image cropping. Note: the image is cropped with a background color)
