Video coding using a pyramidal Gabor expansion

A compression technique based on an expansion is presented. The elementary functions of the expansion form a class of pyramidal Gabor functions covering the frequency domain in octave bands. The image sequence is coded by differentially coding selected coefficients of this expansion. Simulation results show sequences reconstructed with good quality for a bit rate less than 64 Kbit/s.
