All Implemented Interfaces:

Signal

public class BinarySignal

extends Object

implements Signal

BinarySignal is a 1-d array of byte. All the values in a BinarySignal are always either 1 or 0.

Field Summary

protected byte[]	data One dimensional byte array
protected int	length Cartesian width

Constructor Summary

BinarySignal()
Creates an empty one dimensional BinarySignal with a length of zero

BinarySignal(BinarySignal img)
Creates a one dimensional BinarySignal (shallow copy) from BinarySignal img

BinarySignal(DiscreteSignal img)
Creates a one dimensional BinarySignal from a DiscreteSignal.

BinarySignal(int x)
Creates a one dimensional BinarySignal with a length of x

BinarySignal(int x, byte[] dat)
Creates a one dimensional BinarySignal with a length of x from array dat.

BinarySignal(RealSignal img)
Creates a one dimensional BinarySignal from a RealSignal.

Method Summary

BinarySignal	compliment() Returns the complement signal of this signal
Signal	copy() Makes a deep copy of this Signal
int	count() Counts the number of "on" pixels
BinarySignal	difference(BinarySignal signal) Returns the difference of this signal and a BinarySignal
byte	get(int x) Returns the pixel value at the given x value
BinarySignal	intersection(BinarySignal signal) Finds the intersection between this image and another BinarySignal
int	length() Returns the width (maximum length value)
void	set(int x, int value) Sets the pixel value at x to a given value
BinarySignal	shift(int horizontal) Performs a shift on this image.
BinarySignal	union(BinarySignal signal) Finds the union between this signal and another BinarySignal

Constructor Detail

BinarySignal

public BinarySignal()

Creates an empty one dimensional BinarySignal with a length of zero

BinarySignal

public BinarySignal(int x)

Creates a one dimensional BinarySignal with a length of x

BinarySignal

public BinarySignal(int x,
                    byte[] dat)

Creates a one dimensional BinarySignal with a length of x from array dat. If dat[k]>0,the value of the signal is set as 1. Otherwise the value is set to 0.

Parameters:

x - width of image

dat - one dimensional array of short. The array is length x.

BinarySignal

public BinarySignal(DiscreteSignal img)

Creates a one dimensional BinarySignal from a DiscreteSignal. It converts a DiscreteSignal to a BinarySignal.

BinarySignal

public BinarySignal(RealSignal img)

Creates a one dimensional BinarySignal from a RealSignal. It converts a RealSignal to a BinarySignal.

BinarySignal

public BinarySignal(BinarySignal img)

Creates a one dimensional BinarySignal (shallow copy) from BinarySignal img

Method Detail

copy

public Signal copy()

Makes a deep copy of this Signal

Specified by:

copy in interface Signal

Returns:

a deep copy of BinarySignal

length

public final int length()

Returns the width (maximum length value)

Specified by:

length in interface Signal

get

public final byte get(int x)

Returns the pixel value at the given x value

Parameters:

x - the length coordinate

set

public final void set(int x,
                      int value)

Sets the pixel value at x to a given value

Parameters:

x - the length coordinate

value - the value to set the pixel to

union

public final BinarySignal union(BinarySignal signal)

Finds the union between this signal and another BinarySignal

Returns:

this

intersection
