Interface Summary

Interface	Description
SceneMetric	A metric interface for comparing the similarity of two different interpretations of a scene.
Transducer	An interface for cut/copy operations that perform recognition on the cut/copied strokes and returns a different DataFlavor than "application/sketch/strokes".

Class Summary

Class	Description
ApproximateStrokeFilter	An object which filters a pen stroke using "approximation by line segments" technique, (Hanaki, Temma, Yoshida, "An On-line Character Recognition Aimed at a Substitution for a Billing Machine Keyboard", Pattern Recognition, Vol.8, pp63-71, 1976).
AveragingStrokeFilter	Smooth a stroke by averaging a point with its neighboring points.
BulletedData	Native class that defines a collection of TextLine's.
BulletedItem	Native class that defines a collection of TextLine's.
BulletedItems	Native class that defines a collection of TextLine's.
BulletedLine	Native class that defines a collection of TextLine's.
BulletedList	Native class that defines a collection of TextLine's.
CachingStrokeRecognizer	A proxy recognizer implementation that caches the result of the target recognizer.
CompositeTransducer	A composite class that can be used to multiplex between different transducers.
DashedPathData	A typed data that holds a recognized dashed path which consists of a Polyline2D path, an average dash length, and an average gap length.
DashedPathRecognizer	This recognizer recognizes dashed paths from sessions of individual strokes.
DehookingStrokeFilter	Eliminate the serifs at the ends of a stroke.
HMMTrainer	Read a training file and train an HMM for scribble recognitoin.
ImageTransducer	Draw the ink into a bitmap image for cut-and-paste.
InterpolateStrokeFilter	For every 2 consecutive points in a stroke, fill in with evenly spaced points until the distance in between any 2 consecutive points no longer exceeds the threshold distance.
LineRecognizer	This recognizer recognizes lines from strokes.
LLRSceneMetric	A scene metric that calculates the accuracy based on the accuracy of the terminal assignments, where a terminal is the direct parent of the stroke in the highest confidence scene interpretation.
LLRSceneRecognizer	A scene recognizer that groups the highest-confidence LLR results into a single tree with 100% confidence.
ModedIncrRecognizer	An abstract class for "moded" incremental recognizers that examines the first part of a gesture to see if it matches its starting signal and thereafter responds to events in a moded interaction.
NormalizeLengthStrokeFilter	Interpolate a timed stroke so that it contains a specified number of points.
NormalizeTimeStrokeFilter	Interpolate a timed stroke so that its points are spaced evenly over time.
PanRecognizer	A recognizer that recognizes "pan" gestures ("P") and then pans left if the events are "left", etc.
PanRecognizer.PanData	A classification type for paning.
PanZoomController	A controller that combines conventional click- and drag-selection on a pane with gesture-based panning and zooming.
PanZoomInterpreter
RemoveDupPtsStrokeFilter	Remove all duplicate adjacent points from a timed stroke.
RetypingRecognizer	FIXME
SceneTranslator	A utility program for translating old scene database files into new scene database files.
SceneTranslator.OldSceneParser	OldSceneParser parses an XML file representing a single interpretation of a scene into a Scene data structure.
SceneTranslator.OldSceneWriter	SceneWriter writes a single interpretation of a scene to an output stream.
ScribbleRecognizer	A recognizer that recognizes scribble shapes: /\/\/\/\
SketchTransducer	Write a sketch model into an XML string.
StrokeFilter	An object which filters a pen stroke in order to reduce the complexity in the raw data points.
TableTransducer	Recognize the ink as a table and make the recognition available as HTML.
TextAnnotations	An abstract typed data that holds a recognized text string and annotations about the geometry of the text including the character height and width.
TextBlock	Native class that defines a collection of TextLine's.
TextData	A typed data that holds a recognized text string.
TextLine	Native class that defines a line of text.
TrainingToMatlab	A utility class for converting training files to text files that can be read into Matlab matrices directly.
ZoomRecognizer	A recognizer that recognizes "zoom" gestures ("Z") and then zooms in if the the events are "down" and out if the events are "up".
ZoomRecognizer.ZoomData	A classification type for zooming.
