The efficient representation of data is a topic of great importance in computing.
In particular, images and volumetric objects are essential elements in Graphic Computing and Visualization and are represented by spatial structures and both their storage and transmission pose challenges in relation to their representations.
The representations based on Wavelets and more recently those based on bandelets, curvelets and countourlets are bases that allow a multi-scale representation of objects and, in many cases, can be considered the best approximation of it.
