Abstract :
This paper proposes a region-selective image compression method that is motivated by the nonuniform sampling structure of the human eye. The approach is based on the nonuniform sampling theorem of Clark et al. (1985) for time-warped bandlimited functions. The theoretical underpinnings of the method are explained and examples are presented to illustrate its implementation and performance.
