getBrightness

public int getBrightness(java.awt.image.BufferedImage src,
                int col,
                int row)

Computes the intensity channel of the pixel at src(x,y).

Parameters:

src -

col -

row -

Returns:

the intensity of src(x,y)

filter

public java.awt.image.BufferedImage filter(java.awt.image.BufferedImage src,
                                  java.awt.image.BufferedImage dest)
