Self similar progressive image coding scheme for multimedia packet switching communications
P. Carlini, Stefano Giordano, Michele Pagano, F. Russo · 2002
Connectionless services provided by best effort networks, such as SMDS and CBDS, are emerging in support of multicast real time communication over a global environment. A major role in the development of these services will be played by voice and video coding. The paper presents a novel coding approach for still images that combines a fractal approach with wavelet transform and multiresolution decomposition. A progressive coding is achieved by finding self-similarities between different scale bands of the wavelet pyramid. This coding technique has been successfully adopted over a regional wide IP environment where some users were connected by dial-up lines, several by N-ISDN and others through a LAN to LAN interconnection service provided by a regional DQDB MAN.
