DESCRIPTION:<span>Co-authors: Richard Brown		(Massey University)\, Robert 
 McLachlan		(Massey University)        <br></span><span><br>A classic probl
 em in image processing is to recognise the similarity or planar objects (p
 oint sets\, curves\, or images) up to transformations from a local planar 
 group such as the Euclidean\, similarity\, and projective groups. Building
  on Cartan&rsquo\;s solution to the equivalence problem\, an influential n
 ew paradigm for this problem was introduced by Calabi et al.\, the differe
 ntial invariant signature. The general theory has been developed extensive
 ly and many examples computed for planar curves\, including the Euclidean\
 , equi-affine\, and projective groups. In this talk we demonstrate how to 
 develop and apply differential invariant signatures for planar images.</sp
