notes for proposed article

[edit]
  • 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
  • some reemergence via SURF (speeded up robust features) descriptor
  • Discuss relationship with steerable pyramid
  • Code
  • Simoncelli, Freeman, Adelson should comment on finished article.
