C# Class Accord.Imaging.Filters.DifferenceEdgeDetector

Difference edge detector.

The filter finds objects' edges by calculating maximum difference between pixels in 4 directions around the processing pixel.

Suppose 3x3 square element of the source image (x - is currently processed pixel): P1 P2 P3 P8 x P4 P7 P6 P5 The corresponding pixel of the result image equals to: max( |P1-P5|, |P2-P6|, |P3-P7|, |P4-P8| )

The filter accepts 8 bpp grayscale images for processing.

Sample usage:

 // create filter DifferenceEdgeDetector filter = new DifferenceEdgeDetector( ); // apply the filter filter.ApplyInPlace( image );
