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)
 * 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)
 * Code
 * http://www.cns.nyu.edu/~eero/steerpyr/
 * Simoncelli, Freeman, Adelson should comment on finished article.
