Reduce Noise

If you scan a picture, you may wish to clean it up before using or tracing it. Scanning can create a picture with noise, or random pixels that are not part of the picture. Noise reduction removes clusters or pixels below a specified size. This is especially useful for autotracing so that you can trace the actual picture without tracing undesired pixels.

Ensure that you do not set the number of pixels to eliminate larger than important picture data when you are reducing background noise.

To reduce noise in an area or picture: Select an area to change, or deselect a selected area if you want to change the entire picture. Choose the ''Reduce Noise'' command from the ''Effects'' menu to open the ''Reduce Noise'' dialog box. Drag the slider the set the maximum number of pixels in a cluster to remove. Click ''Perform''.
