Constructor Detail

Position

public Position(int x,
                int y,
                int intensityR,
                int intensityG,
                int intensityB)

Holds pixel information i.e. its location, intensity & state

Initially state will be set as inactive ( 0 )

When Pixel location has been explored, it can be set as active ( 1 )

And after all neighbours explored for this location, its state to be set as dead ( 2 )

Parameters:

x - X-coordinate of Pixel location

y - Y-coordinate of Pixel location

intensityR - Red color component intensity at I[y, x]

intensityG - Green color component intensity at I[y, x]

intensityB - Blue color component intensity at I[y, x]

Method Detail

getX

public int getX()

Returns:

X-coordinate of Pixel

getY

public int getY()

Returns:

Y-coordinate of Pixel

getIntensityR

public int getIntensityR()

Returns:

Red color intensity at this location

getIntensityG

public int getIntensityG()

Returns:

Green color intensity at this location

getIntensityB

public int getIntensityB()

Returns:

Blue color intensity at this location

getState

public int getState()

Returns:

State of pixel ( inactive = 0, active = 1, dead = 2 )

setState

public void setState(int state)

Updates state of Pixel

Parameters:

state - State of pixel

isIntensityRWithInRange

public boolean isIntensityRWithInRange(int targetIntensity,
                                       int relaxation)

Checks whether this pixel's red component intensity satisfies

targetIntensity - relaxation <= intensity <= targetIntensity + relaxation

or not

Parameters:

targetIntensity - target intensity, with which this pixel's intensity to be compared

relaxation - targetIntensity - relaxation <= intensity <= targetIntensity + relaxation, needs to be satisfied

Returns:

Result of comparison as true / false

isIntensityGWithInRange

                                       int relaxation)

Checks whether this pixel's green component intensity satisfies

targetIntensity - relaxation <= intensity <= targetIntensity + relaxation

or not

Parameters:

targetIntensity - target intensity, with which this pixel's intensity to be compared

relaxation - targetIntensity - relaxation <= intensity <= targetIntensity + relaxation, needs to be satisfied

Returns:

Result of comparison as true / false

isIntensityBWithInRange

public boolean isIntensityBWithInRange(int targetIntensity,
                                       int relaxation)

Checks whether this pixel's blue component intensity satisfies

targetIntensity - relaxation <= intensity <= targetIntensity + relaxation

or not

Parameters:

targetIntensity - target intensity, with which this pixel's intensity to be compared

relaxation - targetIntensity - relaxation <= intensity <= targetIntensity + relaxation, needs to be satisfied

Returns:

Result of comparison as true / false
