Edge Detect Filter

 
 
 

Detects lines or edges wherever there is a change in intensity over a small area of pixels, and draws these edges with an intensity proportional to the amount of change.

Requires an Input (Any).

Produces an Output (Any).

Parameters

Detect Type

Sets the type of algorithm used for detecting edges. Select Sobel, Prewitt or Nevatia. Each algorithm produces a slightly different effect; for example, Nevatia produces less noise in areas of low frequency.

Min Level

Sets the minimum change in intensity required to be detected as an edge. The higher the value, the greater the change in intensity required for an edge to be detected.

Scale

Sets the intensity with which edges are drawn. The higher the value, greater the intensity.

Mask
