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)
Decoding a fractal compressed image can be seen as solving an aane two-scale functional equation. If the aane term is zero, the dilation equation becomes linear and the solution is similar to the scaling functions from wavelet theory. In both cases a linear operator, parameter-ized with a few variables determines a complicate looking function. We present… (More)
The results of developing a system to illuminate the premises with the use of photovoltaic cells.
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)
