加权平均图像融合算法

c++语言或MATLAB编程对256×256的灰度图像进行8×8DCT变换，对变换后的结果进行处理： 采用区域编码和阈值编码方法实现图像压缩，保留 50％ 的系数(区域编码保留前 50%个系数，阈值编码保留 50%的大系数）； 再反变换后，对比原始图像和处理后的图像。(C++ or MATLAB programming performs 8 * 8DCT transform on 256 * 256 grayscale images, processing the transformed results: The region coding and threshold coding are used to compress the image, and the coefficient of 50% is retained (the first 50% coefficients are reserved for the region code and the large coefficient of the threshold code is retained by 50%). After inverse transformation, the original image and the processed image are compared.)

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.)
