open-in-new
<p>The <a href="/facts/Scale_space_representation/XJNvTH1N">scale space representation</a> of a signal obtained by <a href="/facts/Gaussian_smoothing/4LzxTJP0">Gaussian smoothing</a> satisfies a number of special properties, <a href="/facts/Scale-space_axioms/zRVymsT4">scale-space axioms</a>, which make it into a special form of multi-scale representation. There are, however, also other types of "multi-scale approaches" in the areas of <a href="/facts/Computer_vision/Tl2Yyk66">computer vision</a>, <a href="/facts/Image_processing/zenalNCf">image processing</a> and <a href="/facts/Signal_processing/Npaja6zb">signal processing</a>, in particular the notion of <a href="/facts/Wavelets/3XcX4uIP">wavelets</a>. The purpose of this article is to describe a few of these approaches: </p>
