#### Chatter Edges *Toolbox:* Preprocessors *Supported ROI(s):* Rectangle, *Supported image type(s):* MONO8, *Description:* Edge detector for noisy or blurred edges. Filter size is programmable. Edge detector developed to find edges created when a mechanical bearing "chatters". The output is a binary or clipped gray-scale image. See [Chatter Edges](ChatterEdges.htm) for more details. *Parameters:* • "edge threshold" \[Integer\] - Edge pixels above this threshold are output as gray-scale or white. *Default value:* 30 *Minimum value:* 1 *Maximum value:* 255 • "keep gray above" \[Bool\] - If true, outputs the filter's gray-scale values above the threshold. If false, outputs white(255) for filter output values above the threshold. *Default value: True* • "filter size" \[Integer\] - size of the differentiator filter separation, in pixels. *Default value:* 16 *Minimum value:* 2 *Maximum value:* 255 • "filter direction" \[Enum\] - direction of the edge detector filter. Values: "X (horizontal)" (default) "Y (vertical)" "X and Y" • "transition" \[Enum\] - transition type to detect Values: "dark-to-light" (default) "light-to-dark" "either" *Outputs:* • None
