A simple class of fractal transforms for hyperspectral images

摘要

A complete metric space of function-valued mappings appropriate for the representation of hyperspectral images is introduced. A class of fractal transforms is then formulated on this space. Under certain conditions, the fractal transform T can be contractive, implying the existence of a unique fixed point. We then formulate a simple class of block transforms for the fractal coding of digital hyperspectral images, and illustrate with an example.
