Filtering Workspace



The purpose of the Filtering workspace is to provide an interface to apply filters on images and to visualize results of filtering processes on a given image by comparatively displaying the output image beside the input image.



Filtering workspace consists of 3 main parts :

- the central window : a comparative view to display result of a filtering processes (view called "Result of filtering") regarding the given input image (view called "Input to be filtered").
- the left panel : "Patient" is a navigator that displays all available images to process belonging to a selected patient.
- the right panel : "View Properties" is the common toolbox for view controls. "Filtering View" is the main toolbox used to select a filter among available filtering processes and to store the results in the database.


Running a filter

To apply a filter on an image, just select an image from the left panel and drag and drop it to the central window ("input to be filtered").

Note : you may also want to switch to another workspace (e.g. Visualization, Diffusion or Registration) then get back. No problem, the current state of the workspaces remains unchanged when switching to another one.
