Classes

CubicInterpolation

Cubic interpolation algorithm

FillPenUpDurations

This transformation fills gaps of online signature by interpolating the last known feature values. Gaps should be represented in the signature with two zero pressure border points.

FillPenUpDurations.TimeSlot

Helper class for FillPenUpDurations

FilterPoints

Removes samples based on a criteria from online signature time series

LinearInterpolation

Performs linear interpolation on the input

NormalizeRotation

Performs rotation normalization on the online signature

NormalizeRotation2

Performs rotation normalization on the online signature

NormalizeRotation3

Performs rotation normalization on the online signature

NormalizeRotationForX

Performs rotation normalization on the online signature

OrthognalRotation

Performs rotation normalization on the online signature

RelativeScale

Maps values of a feature to a specific range.

InputFeature: feature to be scaled.

OutputFeature: output feature for scaled InputFeature

ResampleSamplesCountBased

Resamples an online signature to a specific sample count using the specified IInterpolation algorithm

SampleRate

Performs rotation normalization on the online signature

Scale

Maps values of a feature to a specific range.

InputFeature: feature to be scaled.

OutputFeature: output feature for scaled InputFeature

TranslatePreproc

This transformations can be used to translate the coordinates of an online signature

UniformScale

Maps values of a feature to a specific range and another proportional.

BaseDimension: feature modelled the base dimension of the scaling.

ProportionalDimension: feature modelled the dimension scaled proportionally to the base dimension.

BaseDimensionOutput: output feature for scaled BaseDimension

ProportionalDimensionOutput: output feature for scaled ProportionalDimension

ZNormalization

Maps values of a feature to a specific range.

InputFeature: feature to be scaled.

OutputFeature: output feature for scaled InputFeature
