Classpublic final class ToneMapping
ImplementsIFilter

The ToneMapping class is a filter that applies a simple tone mapping to the image.

This filter calculates the world luminance first using \small\exp(\frac{\sum_{x,y}{log(1+Y(x,y))}}{width \cdot height}).

The scale for the luminance is defined by dividing the world luminance by 18. After all for each pixel is the new luminance function \small lum(x,y) = \frac{Y(x,y) \cdot scale}{1+Y(x,y) \cdot scale} used.

Supported formats:


Example 
  
  var filter: ToneMapping = new ToneMapping();
  
  var video: WebCam = new WebCam( 160, 120 );
  var image: Image = new Image( 160, 120, ImageFormat.RGB );
  
  image.loadBitmapData( video.getCurrentFrame(), true );
  
  filter.apply( image );
