In the Sketch dialog box, adjust any of the following sliders:
|
• |
Sensitivity - determines sensitivity to detail. Low values detect only the main
edges. High values detect the main edges as well as thin lines, such as the lines
around a person's eyes.
|
• |
Smoothing - determines how much noise is filtered out. Higher values result
in wider, lighter, and blurrier lines.
|
• |
Grain - determines how much of the paper grain is revealed in the sketch
marks. Move this slider to the right to show more of the paper grain.
|
• |
Threshold - removes noise after edge detection. Threshold High is used to flag
light pixels which may be just noise in the image. Threshold Low is used to test
surrounding pixels.
