Edge Detect
Detect the edges in an image.
Edge Detect
Method #
This node evaluates an image to try and identify details and edges within. Useful for creating neon effects from a simple video image with a Glow node, or for highlighting edges of an image when in additive mode.
Parameters
These properties control the core behaviours of the node.
Parameter Details
Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount Changes the opacity of the new effect over the original image.
Blend Mode (RGB) Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha) Change how the generated effect blends with the parent image alpha.
Mode Change which edge detection method is used.
Colour Edit the colour of the edge
Threshold Change the threshold for the edge detection.
Scale Scale the brightness for the effect.
Width Change the width of the output lines detected.
Pixel Width When sobel mode is chosen pixel width defines the width of the edge
