  • 区域编码和阈值编码实现压缩
    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.)
