本文证明了一种非正交离散余弦变换──DC3T具有与经典DCT相同的残余相关和更高的变换编码增益,分析了它的熵压缩和能量压缩性质,给出了计算复杂度和递推算法.结果表明DC3T比DCT更适合于图像数据压缩.
A non-orthogonal DCT
the DC3T
is proved to have equal residual correlation as and higher transform gain over the well-known DCT
its entropy and energy compression properties along with its computations are provided.
