Image compression by Gabor expansion
M. Kunt · Optical Engineering · 1991
A compression technique based on a pyramidal expansion is presented. The elementary functions of the expansion form a class of pyramidal Gabor functions partitioning the frequency domain into different regions. Still images and moving image sequences are coded by Selecting and quantizing the coefficients in this expansion. Computer simulation of the proposed method show good quality reconstruction of both still images and image sequences.
