EdgeDetect: Blips In the S_EdgeDetect Plugin. Performs an edge detect on the source image, then finds the intersection of the edges with a rotating beam. The result of this effect can be used to create dots that cycle around the edges of an object, probably for further processing such as with Glint. Inputs: Source:  The clip to be processed.

Parameters:

Center:   X & Y,   Default: [0 0],  Range: any.
The center location of the rotating beam, in screen coordinates relative to the center of the frame. This parameter can be adjusted using the Center Widget.

Angle Start:   Default: 0,  Range: any.
The initial beam angle.

Angle Speed:   Default: 180,  Range: any.
The speed of beam rotation in degrees per second. For variable beam rotation speed, set this to zero and animate the Angle Start parameter.

Beam Width:   Default: 0.05,  Range: 0.001 or greater.
The width of the rotating beam.

Beam:   Popup menu,  Default: 1 Way.
Selects the type of beam.

1 Way:  the beam starts at the Center location and extends outwards in a single direction based on the Angle.

Bidirectional:  the beam extends in both directions from the Center location.

Brightness:   Default: 1,  Range: 0 or greater,  Shared.
Scales the brightness of the result.

Saturation:   Default: 1,  Range: 0 or greater,  Shared.
Scales the color saturation of the result. Increase for more intense colors. Set to 0 for monochrome.

Threshold:   Default: 0,  Range: 0 or greater,  Shared.
Subtracts this value from the result. Increase to remove unwanted noise from minor edges.

Edge Smooth:   Default: 0,  Range: 0 or greater.
Increase for thicker and smoother edges.

Show:   Popup menu,  Default: EDGESxBEAM.
Selects between output options.

EDGESxBEAM:  outputs the edge image intersected with the beam.

EDGES:  outputs only the edge image. Use this when adjusting the edge parameters.

BEAM:  outputs only the beam images. Use this when adjusting the beam parameters.
