In this work we present a fractal image compression algorithm for interrintra-frame video coding. We h a ve shown previously how the Iterated TransformationThe-ory ITT compression algorithm proposed by Jacquin can be modeled as the solution of a second kind two-scale functional equation. This approach allows us to introduce a chain of functional equations(More)
We present a new method that extracts lacunarity descriptors from textured regions using wavelet maxima. The distributions of the local wavelet maxima density in a sliding window over the region of interest are compared using different method in order to generate lacunarity parameters. The algorithms have been tested on data from the MelaFind skin cancer(More)
