Homogenity edge detector.

Namespace:  AForge.Imaging.Filters
Assembly:  AForge.Imaging (in AForge.Imaging.dll) Version: 2.2.3.0 (2.2.3.0)

Syntax

C#
public class HomogenityEdgeDetector : BaseUsingCopyPartialFilter

Remarks

The filter finds objects' edges by calculating maximum difference of processing pixel with neighboring pixels in 8 direction.

Suppose 3x3 square element of the source image (x - is currently processed pixel):

Copy 
P1 P2 P3
P8  x P4
P7 P6 P5
The corresponding pixel of the result image equals to:
Copy 
max( |x-P1|, |x-P2|, |x-P3|, |x-P4|,
     |x-P5|, |x-P6|, |x-P7|, |x-P8| )

The filter accepts 8 bpp grayscale images for processing.

Sample usage:

CopyC#
// create filter
HomogenityEdgeDetector filter = new HomogenityEdgeDetector( );
// apply the filter
filter.ApplyInPlace( image );

Initial image:
