List of Spatial Filters

The following is a list of the predefined spatial filters that can be applied using the SpatialFilterCommand:

Value

Meaning

EmbossNorth

EmbossNorthEast

EmbossEast

EmbossSouthEast

EmbossSouth

EmbossSouthWest

EmbossWest

EmbossNorthWest

Creates an image with an embossed appearance. (This is used for artistic effect, but is listed here because it is one of the predefined filters.) Choose the appropriate value for the direction of the effect.

GradientEdgeEnhancementNorth

GradientEdgeEnhancementNorthEast

GradientEdgeEnhancementEast

GradientEdgeEnhancementSouthEast

GradientEdgeEnhancementSouth

GradientEdgeEnhancementSouthWest

GradientEdgeEnhancementWest

GradientEdgeEnhancementNorthWest

Detects edges using a Gradient directional filter. All pixels not on the detected edges are changed to black. Choose the appropriate value for the direction of the effect.

LaplacianFilter1

LaplacianFilter2

LaplacianFilter3

LaplacianDiagonal

LaplacianHorizontal

LaplacianVertical

Applies Laplacian line detection. There are three omnidirectional filters and three bi-directional ones. All pixels not on the detected lines are changed to black.

SobelHorizontal

SobelVertical

Applies Sobel edge detection. All pixels not on the detected edges are changed to black. (The usage is the same as Prewitt, but the algorithm is different.) Choose the appropriate value for horizontal or vertical detection.

PrewittHorizontal

PrewittVertical

Applies Prewitt edge detection. All pixels not on the detected edges are changed to black. (The usage is the same as Sobel, but the algorithm is different.) Choose the appropriate value for horizontal or vertical detection.

ShiftAndDifferenceDiagonal

ShiftAndDifferenceHorizontal

ShiftAndDifferenceVertical

Applies shift-and-difference edge detection. All pixels not on the detected edges are changed to black. Choose the appropriate value for diagonal, horizontal, or vertical detection.

LineSegmentHorizontal

LineSegmentVertical

LineSegmentLeftToRight

LineSegmentRightToLeft

Applies line segment line detection. You can use this filter to find line discontinuities in an image. All pixels not on the detected line segments are changed to black. Choose the appropriate value for horizontal, vertical, left-to-right diagonal, or right-to-left diagonal detection.
