Class LineProperties

java.lang.Object
  org.shapelogic.imageprocessing.LineProperties

All Implemented Interfaces:

Calc0<java.util.Set<LineType>>, CalcInvoke<java.util.Set<LineType>>, CalcValue<java.util.Set<LineType>>, LazyCalc<java.util.Set<LineType>>

public class LineProperties
extends java.lang.Object
implements CalcInvoke<java.util.Set<LineType>>

LineProperties contains properties that are important for a line when you are dealing with curved multi line.

Sami Badawi Properties to keep track of Min and max point Number of positive, almost zero and negative pixels Sum of positive and sum of negative distances If direction change for the 2 adjacent point is different sign Assumptions I do not think that this class is going be reused

LineProperties()

Method Summary

LineType	calcLineType() The main LineType for a line there are 3 options: straight, arch, wave.
double	distanceToPoint(CPointInt point) Same unnormalized point distance to line used in splitting line.
java.util.Set<LineType>	getValue() Starts a lazy calculation.
java.util.Set<LineType>	invoke()
boolean	isConcaveArch() lineType needs to be set first.
boolean	isDirty() When dirty is false that means that the calculated value can be used
void	setup() Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.

Method Detail

setup

public void setup()

Description copied from interface: LazyCalc

Currently not super well define used for 2 purposes: Reset: called from the outside if you want to reuse it init: Called from the inside when calculation start to have everything setup maybe the semantic could work for both? TODO: This should be separated better.

Specified by:

setup in interface LazyCalc<java.util.Set<LineType>>

invoke

public java.util.Set<LineType> invoke()

Specified by:

invoke in interface Calc0<java.util.Set<LineType>>

getValue

public java.util.Set<LineType> getValue()

Description copied from interface: CalcValue

Starts a lazy calculation. If dirty do calc() else return cached value. This should maybe be moved up in the hierarchy

Specified by:

getValue in interface CalcValue<java.util.Set<LineType>>

calcLineType

public LineType calcLineType()

The main LineType for a line there are 3 options: straight, arch, wave.

distanceToPoint

public double distanceToPoint(CPointInt point)

Same unnormalized point distance to line used in splitting line.

Parameters:

point - an input

Returns:

unnormalized distance to the line from the star to end point

isConcaveArch

public boolean isConcaveArch()

lineType needs to be set first.

isDirty

public boolean isDirty()

Description copied from interface: LazyCalc

When dirty is false that means that the calculated value can be used

Specified by:

isDirty in interface LazyCalc<java.util.Set<LineType>>
