Detailed Description

A class representing a unistroke gesture

This object represents a normalized unistroke gesture stored inside of a gesture recognizer. As the normalization algorithm is deteremined by the current settings, there are no publicly accessible constructors for this class.

Constructor & Destructor Documentation

UnistrokeGesture()

cugl::UnistrokeGesture::UnistrokeGesture ( )

inline

Creates an uninitialized gesture with no information

Member Function Documentation

getAngle()

float cugl::UnistrokeGesture::getAngle

(

const UnistrokeGesture &

other

)

const

Returns the (normalized) angles between the two gestures

Parameters

other

The gesture to compare

Returns

the (normalized) angles between the two gestures

getDollarSimilarity()

float cugl::UnistrokeGesture::getDollarSimilarity

(

const UnistrokeGesture &

other

)

const

Returns the $1 similarity between the two gestures

Parameters

other

The gesture to compare

Returns

the $1 similarity between the two gestures

getName()

const std::string cugl::UnistrokeGesture::getName ( ) const

inline

Returns the string identifier of this gesture

Returns

the string identifier of this gesture

getOrientation()

const Vec2 & cugl::UnistrokeGesture::getOrientation ( ) const

inline

Returns the orientation of the gesture.

The orientation is defined as the vector from the initial point to a (normalized) centroid. This allows us to control the rotation of gestures.

Returns

the orientation of the gesture.

getPoints()

const std::vector< Vec2 > & cugl::UnistrokeGesture::getPoints ( ) const

inline

Returns the vector of 2D points representing this gesture

Returns

the vector of 2D points representing this gesture

getProtractorSimilarity()

float cugl::UnistrokeGesture::getProtractorSimilarity

(

const UnistrokeGesture &

other

)

const

Returns the PROTRACTOR similarity between this gesture and the other

Parameters

other

The gesture to compare

Returns

the PROTRACTOR similarity between the two gestures

getVector()

const std::vector< float > & cugl::UnistrokeGesture::getVector ( ) const

inline

Returns the vectorized representation of this gesture.

The vectorized representation is a normalized, high dimensional vector.

Returns

the vectorized representation of this gesture.
