Jenifer, there's an example implementation of Gabor filters on Wikipedia: http://en.wikipedia.org/wiki/Gabor_filter#Example_implementation

[Walter Roberson]

But those are Gabor filters rather than Log Gabor filters.

Answer 2

[Walter Roberson]

Implementation can follow the description in the paper http://digital.csic.es/bitstream/10261/14763/1/LogGabores.pdf

The paper does reference a MATLAB toolbox that has log gabor filters, but I do not at present see a way to download it. You might have to email the corresponding author of the paper.

[Laurent]

You may simply achieve this in the Fourier domain by designing your filters with a logarithmic scale of frequencies.

if you are interested in python code, something similar is coded using the package available @ https://pythonhosted.org/LogGabor/
