Talk:Steerable filter

notes for proposed article

origin of the term steerable
- terminology variant from Linköping: controllable
pioneers behind the method: Granlund, Knutsson, Freeman, Adelson
mathematical underpinnings: Gaussian jets, Koenderink's formalism
quadrature pairs: energy and phase
analytical, exact steerability vs. approximate steerability via SVD
steerable, separable filters
Perona's extension: scalable filters
applications
- interest point characterization (Schmid, Mohr)
- edge and line detection (Freeman, Adelson)
- texture recognition (Malik et al.)
connection to Gabor filters
examples from ter haar Romeny & Lindeberg chapter
fell out of favor with emergence of haar-like wavelets used in Viola-Jones and Varma and Zisserman's texture recognition method
- Or did it fall out of favor? Maybe in the realm of fast feature detection. — Preceding unsigned comment added by Serge.Belongie (talk • contribs) 22:22, 6 January 2012 (UTC)[reply]
some reemergence via SURF (speeded up robust features) descriptor
Discuss relationship with steerable pyramid
- should it remain a separate article? — Preceding unsigned comment added by Serge.Belongie (talk • contribs) 22:38, 6 January 2012 (UTC)[reply]
