Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Fractal image compression method

Eastern-European Journal of Enterprise Technologies, 2014
The fractal image compression method is investigated. Among various coding methods, it allows to get the highest compression ratios. The mathematical model is considered, and classical algorithm of image coding-decoding using the fractal method is presented. Its essence lies in searching self-similar image parts based on compression parameters.
