Field Detail

blur

public java.awt.image.ConvolveOp blur

A ConvolveOp object for blurring.

edge

public java.awt.image.ConvolveOp edge

A ConvolveOp object for finding edges.

threshold

public int threshold

myBuffer

public java.awt.image.BufferedImage myBuffer

myGraphics

public java.awt.Graphics2D myGraphics

myRaster

public java.awt.image.WritableRaster myRaster

rgb

public int[] rgb

Constructor Detail

PixelOperater

public PixelOperater(java.lang.String[] args,
                     int _w,
                     int _h)

Method Detail

main

public static void main(java.lang.String[] args)

Notice I start video now in main

grabReference

public void grabReference()

This stores the current frame for future reference.

newFrame

public void newFrame()

This is the classice nested video loops for scanning through each row and then each column with the row of vdeo.

Specified by:

newFrame in interface VideoListener

Overrides:

newFrame in class WindowWithVideo

performPixelOp

public void performPixelOp(int _x,
                           int _y)

I farmed this out to another method because this is the most likely thing you would want to overide

paint

public void paint(java.awt.Graphics g)

Description copied from class: WindowWithVideo

This gets called everytime you repaint the screen. You would want to override this if you want anything but side by side pictures

Overrides:

paint in class WindowWithVideo

keyPressed

public void keyPressed(java.awt.event.KeyEvent e)

Specified by:

keyPressed in interface java.awt.event.KeyListener

Overrides:

keyPressed in class WindowWithVideo

setEdge

public void setEdge(float[] matrix,
                    int size)

Set up the edge detection. This sets the kernel in case you know what that is. You never really have to set this. The default matrix is,
{ 0.0f, -1.0f, 0.0f,
-1.0f, 4.0f, -1.0f,
0.0f, -1.0f, 0.0f };
always a classic. The size is 3 as in 3x3.

setBlur

public void setBlur(int size)

Sets the degree of blur. This takes an integer that describes how many pixels around each pixel to take into account when averaging. The default is 5 and bigger numbers will really slow things down.

blurRaster

public void blurRaster(java.awt.image.WritableRaster _raster)

edgeRaster

public void edgeRaster(java.awt.image.WritableRaster _raster)
