VR-Render basic image filtering

Several filters have been added in VR-Render allowing to basically modify a selected image. When a filter is applied, a copy of the selected image is created and added in the image selector. To distinguish the resulting image from the native image, the selector indicates a set of information allowing to precisely know the origin of the image and the parameter of the filter that has been used (see next image). This information is located in the comment area and is presented as follows: In : Operator [Iorigin] (parameters of the operator), where n is an automatic incremental value from 1, In the nth images resulting from filtering application and Iorigin the image on which the Operator is applied.

In VR-Render 0.8, we have decided to limit the set of filters to five basic operators: Rotation (90° rotation for decubitus patient position), Cropping (limitation of the initial image to a reduced area), Subsampling (reducing the number of slice and thus increasing the voxel dimension of the selected axis), Windowing (reducing or increasing the initial grey level to a new defined window) and Median (smoothing the initial image with a median filter). Each selection of these operators starts a window allowing to parameterize the operator (see next image).
