- I have implemented "steerable filters" (Freeman & Adelson, PAMI Sept.
- 1991)
- using PV~WAVE. Filtering via convolution in frequency domain. I only
- implemented line element rather than edge detection & location.
-
- You should checkout the MegaWave package from France. It does anisotropic
- blurring (Saint-Marc, Chen, & Medioni; PAMI June 1991).
