3-6 An Image Approximation Method Using Deformable Continuous Functions and Its Application to Image Coding

Abstract

In the previous work, we proposed an image approximation method based on a linear combination of deformable continuous functions and showed its potential as a new image coding tool. In this paper, we investigate the statistical properties of parameters which describe shapes of the functions optimized by our method. Based on the results, we also introduce an entropy coding technique into several kinds of the parameters aiming at better coding performance.
