Properties

OptionalgaussianBlurOptions

gaussianBlurOptions?: GaussianBlurOptions

Standard deviation of the gaussian blur (sigma). Value must be between 0 and 1.

Default

{ sigma: 1 }

OptionalhighThreshold

highThreshold?: number

Higher threshold of the gaussian blur (indicates the strong edges to keep). Value must be between 0 and 1.

Default

0.1

Optionalhysteresis

hysteresis?: boolean

Enable/ disable hysteresis steps.

Default

true

OptionallowThreshold

lowThreshold?: number

Lower threshold of the gaussian blur (indicates the weak edges to discard).

Default

0.04

Optionalout

out?: Mask
