本文将DCT变换与SPECK算法相结合
提出了一种基于DCT变换的渐进式图像编码方法.该方法充分利用了DCT变换实现简单的特点
还能充分发挥零树编码的优势实现对图像的高效压缩.输出码流具有嵌入的特性
便于码率控制
具有一定的抗误码能力.同时计算复杂度低
比较适合于低复杂度的图像编码与传输.
DCT transform and SPECK algorithm are combined in this paper. A DCT-based approach to progressive image coding is proposed
which has the characteristic of simplicity and can achieve high compression using zerotree coding method.The output stream is embedded
which is easy to control rate
and error resilient.The algorithm has low computational complexity so it is suitable for image coding and transmission with low complexity.
