-Even

Use the even symm. Gabor filter, as described by Farrokhnia

-Gen

Use the general Gabor filter, as described by Dunn. Parameters: SigmaX, SigmaY

-s

Filter structure string, defined as a quad tree. See the module filtertree (CompileFiltStructTree) for a description of the structure.

-sb

Filterstructure string, defined as a binary tree. See the module filtertree (CompileFiltStructTreeFromBin) for a description of the structure.

-sn

Filter structure number, between 1 and 11 (default 4). See the module filtertree (BuildFiltStructTree) for a description of the structure.

-tanh

Use the tanh() nonlinearity, as described by Farrokhnia

-alpha

alpha parameter in tanh() nonlinearity, as described by Farrokhnia

-U0

Centre frequency parameter(s) to the Gabor filter and the tanh() nonlinearity

-V0

Second centre frequency parameter(s) for a general Gabor filter. If specified, the number of values must equal the number of values for U0. See Dunn.

-theta

Angle parameter(s) to the Gabor filter.

-suvf

Sigma U factor: parameter to the Gabor filter (Farrokhnia) Sigma V factor: parameter to the Gabor filter (Farrokhnia)

-sf

Factor to sigma in tanh()

-navg

Do not average the feature-images

-nnl

Do not perform any nonlinear transform, or rather only apply the magnitude operation.

A parametervalue of -1 means automatic calculation This program will not accept inputsequences with more than one frame. Specifying no parameters implies applying a even-symmetric Gabor filter with Farrokhnias default parameters.
