| Abstract: | Wavelets, fundamental component of the latest image coding standard JPEG 2000, have proven to be a very useful tool in representation and coding of 2D images. They are also a powerful instrument in catching zero-dimensional singularities, though less efficient in dealing with ?edge? singularities. Ridgelets, by definition, are a powerful tool in catching and representing line singularities in bidimensional space.In this paper we propose a hybrid approach that combines both Ridgelets and Wavelets for a more efficient representation of 2-D images with edgesResults confirm the potential of the combined use of Wavelets and Ridgelets as efficient representation, showing substantial improvements when compared to only Wavelets. | ||
