C# Class Accord.Imaging.Filters.HomogenityEdgeDetector

Homogenity edge detector.

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): P1 P2 P3 P8 x P4 P7 P6 P5 The corresponding pixel of the result image equals to: 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:

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