Gabor Model
The Gabor function model of cortical receptive fields was first proposed by Marcelja in 1980
[Marcelja 1980] however the functions themselves are often credited to Gabor
[Gabor 1946] who supported their use in communications.
- Gabor functions are complex valued functions.
- In 1D they can be characterized as the product of a complex exponential and a Gaussian.
These are plots of the real and imaginary parts (left and right respectively) of a 2D function
made up of a Gabor function along the x-axis and a Gaussian along the y-axis. As was the case
with the receptive fields, these functions have some nominal activity (grey) which inceases (white)
and decreases (black) in local, oriented bands.
