IEEE Region 10 International Conference TENCON
作者: M. Das N.K. Loh Department of Electrical and Systems Engineering Oakland University Rochester MI USA
Adaptive predictive coding of digitized images using multiplicative autoregressive (MAR) models is discussed. Three MAR models, designated as nonsymmetric half plane (NSHP) (3*3), quarter plane (QP) (2*3), and NSHP (2... 详细信息
