Visualization of the day: Steerable filters

Ooh is that Gabor am I seeing? angle, frequency/wavelength and phase adjustable complex 2d filters I remember something like that from university

Similar, this is the first derivative of a Gaussian.

Interactive demo:

Do eigenfaces next!

On my to do list. Going to have a lot of fun building out new visualizations for my computer vision course this fall 🤓

Nice! How do these relate to the more recent steerable filters proposed by Worrall et al. 2017 (for 2D) and Weiler et al. 2018 (for 3D)?
