Meziantou.FrameworkEdgeDetector Enum
Selects the operator of ImageProcessingExtensions.DetectEdges.
public enum EdgeDetectorFields
| Name | Value | Description |
|---|---|---|
Sobel | 0 | The magnitude sqrt(gx^2 + gy^2) of the gradients of ConvolutionKernel.SobelX and ConvolutionKernel.SobelY. |
Scharr | 1 | The magnitude sqrt(gx^2 + gy^2) of the gradients of ConvolutionKernel.ScharrX and ConvolutionKernel.ScharrY. |
Prewitt | 2 | The magnitude sqrt(gx^2 + gy^2) of the gradients of ConvolutionKernel.PrewittX and ConvolutionKernel.PrewittY. |
Kirsch | 3 | The largest response of the eight Kirsch compass matrices: [5, 5, 5; -3, 0, -3; -3, -3, -3] (north) and its seven rotations by 45 degrees, made by moving the eight outer weights around the middle one. |
Robinson | 4 | The largest response of the eight Robinson compass matrices: ConvolutionKernel.SobelX and its seven rotations by 45 degrees, made by moving the eight outer weights around the middle one. Each matrix is the negation of the opposite one, so the largest response is the largest absolute response of four of them. |
Laplacian3x3 | 5 | The absolute value of the response of ConvolutionKernel.Laplacian3x3. |
Laplacian5x5 | 6 | The absolute value of the response of ConvolutionKernel.Laplacian5x5. |
LaplacianOfGaussian | 7 | The absolute value of the response of ConvolutionKernel.LaplacianOfGaussian. |
