2D Gabor Wavelet Transform and Inverse Transform (Reconstruction) Demo
using Matlab
http://visiome.neuroinf.jp/modules/xoonips/detail.php?item_id=6894

This Matlab script performs a 2D Gabor Wavelet Transform on an arbitrary image,
displays the resulting transform, and then performs the inverse transform
*slowly* and *sequentially* in animation. With it, one can visualize how the
original image is reconstructed by summing many Gabor wavelets.

Hope this is useful for explaining what simple cells do.

Cheers!
