变化检测是从不同时期的遥感数据中定量分析和确定地表变化的特征与过程；遥感变化检测是一个确定和评价各种地表现象随时间发生变化的过程；遥感变化检测是遥感瞬时视场中地表特征随时间发生的变化引起两个时期影像像元光谱响应的变化(Change detection is the characteristic and process of quantitative analysis and determination of surface variation in remote sensing data different periods. Remote sensing change detection is a process of determining and uating various surface phenomena over time. Remote sensing change detection is the change of the surface feature over time in remote sensing instantaneous field.)

二维图形图像处理，高斯平滑的源代码，图像预处理(Two-dimensional graphic image processing, Gaussian smoothing of the source code, image preprocessing)

这个算法是仿真linghong的基于指纹码的方法 内有最新的指纹奇异点检测算法(the simulation algorithm is based on fingerprint linghong the code within the latest fingerprint singular point detection Algorithm)

matlab本身不带yuv视频读取函数，此函数读取并转换为RGB格式保存(Matlab itself does not have the yuv video reading function, which is read and converted to RGB format)

提出一种基于特征点的运动场景图像拼接算法。基于相似变换消除选取在运动物体上的特征点，并使用RANSAC算法进行外点的剔除。在融合阶段，根据齐次变换矩阵求得对2幅图像的差异图像，并执行区域增长算法。从而分割出运动区域。使用一种分段映射算法生成全景图像。实验证明了算法的有效性。(A feature-based algorithm for image mosaics of 8c宅Iles with moving objects is pI．oposcd．The algorithm eliminates the feature points which arc selected in moving objects using similarity transform，and the outliers are eliminated using RANSAC algorithm．In the image blend phase，a difference of two images is created using homogeneous transformation matrix，and a region growth algorithm is implemented SO as to segment the movmg object region．A piecewise mapping algorithm for generating panoramic images is used．Experimental results show the effectiveness of the algorithm．)

运用小波阈值实现图像去噪，同时有小波的分解与重构。(Wavelet threshold is used to realize image denoising and wavelet decomposition and reconstruction.)

说明：  使用了色调映射算法，调整图片的灰度，更好表达原图里的信息与特征。(The hue mapping algorithm is used to adjust the gray level of the image and better express the information and features in the original image.)

说明：  雷达模拟LFM脉冲信号，模拟目标回波（目标距离50km，速度100m/s）和噪声信号（信噪比）(Radar simulated LFM pulse signal, simulated target echo (target distance 50km, speed 100M / s) and noise signal (signal-to-noise ratio))
