DetectEdges

Detects the edges in the current image using various one and two dimensional algorithms. If the greyscale parameter is set to false the detected edges will maintain the pixel colors of the originl image.

public ImageFactory DetectEdges(IEdgeFilter filter, bool greyscale = true)
    

Parameters

filter

The ImageProcessor.Imaging.Filters.EdgeDetection.IEdgeFilter to detect edges with.

greyscale

Whether to convert the image to greyscale first. Defaults to true.

Available filters are:

• KayyaliEdgeFilter
• KirschEdgeFilter
• Laplacian3X3EdgeFilter
• Laplacian5X5EdgeFilter
• LaplacianOfGaussianEdgeFilter
• PrewittEdgeFilter
• RobertsCrossEdgeFilter
• ScharrEdgeFilter
• SobelEdgeFilter
