Image Filters
This option is in the Viewer's Image Menu. The user can select from a list of built-in and user-defined filters. Filters can be 1-D (temporal), 2-D (slice) or 3-D (multi-slice). Temporal and spatial filtering can both be applied to a 4-D image. Most filters act immediately when selected, but the Rank Filter opens a dialog window with options for size, (min, max, median), (slice, image volume, time), providing customization based on needs. NOTE: Filtering operations cannot be undone, but reload will reset the image to its unfiltered state. The built in filters should be adequate for a normal user, but those with knowledge and experience in filter design should enjoy making filters customized for your applications using the 'Add/Edit Filter...' option from the Toolbox Options menu.
