Enhanced hierarchical mask creation for image coding using saliency maps

摘要

In this paper we analyse a basic hierarchical mask creation methods for image coding using saliency maps. For saliency maps (SM) based image coding we use specific extension of SPIHT algorithm called SM SPIHT that extends region of interest encoding to encoding with individual weight of importance for each pixel in image using the form of saliency map. This approach is proved to be effective. In this article, we compare basic hierarchical mask creation methods and provide one new method that outperforms all previous methods.
