CINoiseReduction

CINoiseReduction

Reduces noise using a threshold value to define what is considered noise. Small changes in luminance below that value are considered noise and get a noise reduction treatment, which is a local blur. Changes above the threshold value are considered edges, so they are sharpened.

• -inputImage <image> : The image to use as an input image. For filters that also use a background image, this is the foreground image.
• -inputSharpness <number> : The sharpness of the final image. The larger the value, the sharper the result. [Default 0.4]
• -inputNoiseLevel <number> : The amount of noise reduction. The larger the value, the more noise reduction. [Default 0.02]
