So the fast algorithms of discrete sine transform, the discrete cosine transform and the discrete W transform are unified.
这样，离散余弦、离散正弦、离散w变换快速算法就有了一个统一的格式。
The theoretical and experimental results show that the proposed algorithm can achieve higher compression efficiency than DCT and the W transform based method in very low bit rate communication.
理论和实验表明，在超低比特率图象通信应用领域，该算法图象压缩效率高，图象恢复效果好。
