public class ThresholdedDifference : BaseFilter2
The filter produces similar result as applying Difference filter and then Threshold filter - thresholded difference between two images. Result of this image processing routine may be useful in motion detection applications or finding areas of significant difference.
The filter accepts 8 and 24/32color images for processing. In the case of color images, the image processing routine differences sum over 3 RGB channels (Manhattan distance), i.e. |diffR| + |diffG| + |diffB|.
// create filter ThresholdedDifference filter = new ThresholdedDifference( 60 ); // apply the filter filter.OverlayImage = backgroundImage; Bitmap resultImage = filter.Apply( sourceImage );
