Witryna首先将图像分割成 (512/8)2 个 8×8 子图像，对每个子图像进行 FFT，这样每个子图像有 64 个傅里叶变换系数。按照每个系数的方差来排序，由于图像是实值的，其 64 个复系数只有一半有差别的。舍去小的变换系数，就可以实现数据压缩。这里，我们保留 32 个系数，实现 2:1 的数据压缩，然后进行逆变换的程序。 Witryna7 gru 2010 · subplot (223);imshow (log (abs (g)), []),color (jet (64)); title ('压缩后频谱图'); g=ifftshift (g); g=uint8 (real (ifft2 (g))); subplot (224); imshow (g, []); 本内容试读结束，登录后可阅读更多下载后可阅读完整内容，剩余1页未读，立即下载
