All Implemented Interfaces:

CustomisableProcess, SourceClassifiable, java.io.Serializable

public class ColorBackgroundSubtractor
extends BackgroundSubtractor

The color version of the general background. You have to set a threshold between 0 and 1 (0%-100%) and a general background color. If the difference between a background pixel (in a specific position) and a pixel in the current frame (in the same position) is less than the threshold value, the pixel of the current frame will be changed to the adjusted background color. The algorithm performs this operation pixel by pixel.

Description copied from class: BackgroundSubtractor

Adds a new frame to the general background.

Overrides:

addFrame in class BackgroundSubtractor

generateFilter

protected void generateFilter()

Description copied from class: BackgroundSubtractor

Generates the general background from the added frames.

Overrides:

generateFilter in class BackgroundSubtractor

public void setThreshold(double threshold)

Sets the threshold value.

Parameters:

threshold - between 0-1.

getBackground

public int getBackground()

Returns the RGB value of the background.

Returns:

You can convert it to java.awt.Color(int rgb)
