We present a computational, group-theoretic approach to steerable functions. The approach is group-theoretic in that the treatment involves continuous transformation groups for wh...

An alternative to representing curves at a single scale or a fixed number of multiple scales is to represent them only at their natural (i.e. most significant) scales. This allo...

A new approach for implementing filters based on order statistics is proposed in this letter. As an illustration realisations of range, a-trimmed mean and WMMR filters are present...
