Constant Constant pattern generator, i.e., a solid, uniform field of the same value. |
|||
|
PatternGenerator A class hierarchy for callable objects that can generate 2D patterns. |
|||
|
Null A constant pattern of zero activity. |
|||
|
HalfPlane Constant pattern on in half of the plane, and off in the rest, with optional Gaussian smoothing. |
|||
|
Gaussian 2D Gaussian pattern generator. |
|||
|
ExponentialDecay 2D Exponential pattern generator. |
|||
|
SineGrating 2D sine grating pattern generator. |

|
Gabor 2D Gabor pattern generator. |
|||
|
Line 2D line pattern generator. |
|||
|
Disk 2D disk pattern generator. |
|||
|
Ring 2D ring pattern generator. |

|
OrientationContrast Circular pattern for testing responses to differences in contrast. |
|||
|
RawRectangle 2D rectangle pattern generator with no smoothing, for use when drawing patterns pixel by pixel. |
|||
|
Rectangle 2D rectangle pattern, with Gaussian smoothing around the edges. |
|||
|
Arc 2D arc pattern generator. |
|||
|
Curve 2D curve pattern generator. |
|||
|
TwoRectangles Two 2D rectangle pattern generator. |
|||
|
SquareGrating 2D squarewave grating pattern generator. |
|||
|
Sweeper PatternGenerator that sweeps a supplied PatternGenerator in a direction perpendicular to its orientation. |
|||
|
Composite PatternGenerator that accepts a list of other PatternGenerators. |
|||
|
SeparatedComposite Generalized version of the Composite PatternGenerator that enforces spacing constraints between pattern centers. |
|||
|
Selector PatternGenerator that selects from a list of other PatternGenerators. |
|||
|
GaussiansCorner Two Gaussian pattern generators with a variable intersection point, appearing as a corner or cross. |
|||
|
Translator PatternGenerator that translates another PatternGenerator over time. |
|||
|
DifferenceOfGaussians Two-dimensional difference of gaussians pattern. |
|||
|
Sigmoid Two-dimensional sigmoid pattern, dividing the plane into positive and negative halves with a smoothly sloping transition between them. |
|||
|
SigmoidedDoG Sigmoid multiplicatively combined with a difference of Gaussians, such that one part of the plane can be the mirror image of the other. |
|||
|
PowerSpectrum Outputs the spectral density of a rolling window of the input signal each time it is called. |
|||
|
Spectrogram Extends PowerSpectrum to provide a temporal buffer, yielding a 2D representation of a fixed-width spectrogram. |
