Abstract— While the need for image‐sequence compression has long been understood, recent applications have shown that existing methods are not always sufficient. A case in point is the class of applications referred to as “very low bit rate.” These applications require the transmission of sequences over very narrow channels, e.g., 9600 bits/s. The compression ratios required are substantially beyond those that can be accomplished (with reasonable image quality) using standard methods. The Gabor transform is a local frequency decomposition which has been proposed as a model of the early stages of human vision. It has found widespread use for a number of tasks in signal and image processing, including image compression. In this paper, we examine Gabor transform‐based coding for image‐sequence transmission at rates near 10 kbits/s.
