针对合成孔径雷达(SAR) 图像含有大量斑点噪声的特点,基于Contourlet 的多尺度、局部化、方向性和各向
异性等优点,并结合隐马尔科夫树( HMT) 模型和隐马尔科夫场(MRF) ,提出了一种基于Contourlet 域持续性和聚
集性的SAR 图像模糊融合分割算法。该算法有效捕获了Contourlet 子带的持续性和聚集性,并分别用HMT 和
MRF 来刻画,再依据模糊测度,将多尺度HMT 和MRF 有机融合,建立Contourlet 域HMT2MRF 融合模型,并导

(1)试利用函数dct2,对该图像进行压缩。压缩时可尝试对DCT 变换后的系数采用不同取舍方法,比较其压缩性能。(函数dct2在matlab本身是有的,可以help dct2看看)
(2)结合课本例8.7.2 的量化方法,对每一个经DCT变换后的8×8 矩阵量化(Huffman编码部分可省略),从而实现图像压缩。在一定压缩比的情况下,和⑴给出的图像质量相比较。
