Method Summary

void	annotate(float[][][] frame) annotate the RGB frame somehow by color pixels in the rendered pixel frame data.
void	annotate(javax.media.opengl.GLAutoDrawable drawable) Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active).
void	annotate(java.awt.Graphics2D g) each annotator is called by the relevant class (e.g.
void	commandForCar(java.lang.String direction)
void	computeCarInfo()
EventPacket<?>	filterPacket(EventPacket<?> in) Subclasses implement this method to define custom processing.
java.lang.Object	getFilterState() should return the filter state in some useful form
int	getRadius()
int	getX0()
int	getY0()
void	giveCarCommands()
void	initFilter() this should allocate and initialize memory: it may be called when the chip e.g.
void	resetFilter() should reset the filter to initial state
void	setRadius(int radius)
void	setX0(int x0)
void	setY0(int y0)
void	speedControl(java.lang.String s1)

Method Detail

filterPacket

public EventPacket<?> filterPacket(EventPacket<?> in)

Description copied from class: EventFilter2D

Subclasses implement this method to define custom processing.

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packet

Returns:

the output packet

giveCarCommands

public void giveCarCommands()

speedControl

public void speedControl(java.lang.String s1)

commandForCar

public void commandForCar(java.lang.String direction)

computeCarInfo

public void computeCarInfo()

getFilterState

public java.lang.Object getFilterState()

Description copied from class: EventFilter

should return the filter state in some useful form

Specified by:

getFilterState in class EventFilter

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter

getRadius

public int getRadius()

setRadius

public void setRadius(int radius)

getX0

public int getX0()

setX0

public void setX0(int x0)

getY0

public int getY0()

setY0

public void setY0(int y0)

annotate

public void annotate(float[][][] frame)

Description copied from interface: FrameAnnotater

annotate the RGB frame somehow by color pixels in the rendered pixel frame data.

Specified by:

annotate in interface FrameAnnotater

Parameters:

frame - the RGB pixel information. First dimension is Y, second is X, third is RGB

annotate

public void annotate(java.awt.Graphics2D g)

Description copied from interface: FrameAnnotater

each annotator is called by the relevant class (e.g. EyeTracker) and enters annotate with graphics context current, in coordinates with pixel 0,0 in UL corner and pixel spacing 1 unit before scaling transform (which is already active).

Specified by:

annotate in interface FrameAnnotater

Parameters:

g - the Graphics2D context

annotate

public void annotate(javax.media.opengl.GLAutoDrawable drawable)

Description copied from interface: FrameAnnotater

Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). The FrameAnnotater then can use JOGL calls to render to the screen by getting the GL context, e.g. the following code, used in the context of an AEChip object, draws a golden lines from LL to UR of the pixel array.

        GL gl = drawable.getGL();
        gl.glBegin(GL.GL_LINES);
        gl.glColor3f(.5f, .5f, 0);
        gl.glVertex2f(0, 0);
        gl.glVertex2f(getSizeX() - 1, getSizeY() - 1);
        gl.glEnd();
 

Specified by:

annotate in interface FrameAnnotater

Parameters:

drawable - the OpenGL drawable components, e.g., GLCanvas

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Specified by:

update in interface java.util.Observer
