Constructor

Parameters:

net	- network, this FP will be added to the end of the list of feature planes
l	- layer index
name	- name of the feature plane
w	- width
h	- height
angles	- number of discrete angles (e.g. speeds, orientations)
speeds	- number of speeds (e.g. speed bands, scale bands)
alpha	- alpha
speed	- speed of this fp
isWTA	- participates in Selective Tuning
visible	- should the FP be presented in the UI
neuron	- neuron strategy (what is the output nonlinearity, or the ODE that defines response)
notify	- notification strategy (deprecated, on the way out)
learning	- are weights adjustable through learning?

FeaturePlaneInput * STSOMFeaturePlane::addFilter	(	Filter *	f,
		FeaturePlaneAbstract *	fp,
		int	type,
		int	fpOutputIndex,
		bool	wta
	)		`[virtual]`

Add an input filter/feature plane pair.

Parameters:

f	- filter
fp	- input feature plane
type	- input type: regular, non-Fourier, masking
fpOutputIndex	- in case input feature plane has more than one output, which one are we interested in
