<br />
{|<br />
|This module can be used to generate a smooth surface segmentation for datasets that were segmented on images with large slice thickness, leading to "staircase" effect. This module was motivated by the need to generate smooth segmentations for prostate MRI images, which typically have high in-plane resolution (0.5mm) relative to the slice thickness (3mm).<br />
<br />
The module operates by resampling the input to isotropic voxel resolution and applying Gaussian smoothing to the resampled image. Note that the resulting image will have larger size than the input.<br />
| [[File:SegmentationSmoothing_example1.png|thumb|400px|Visualization of the segmentation surface before (green) and after (blue) smoothing using this module. Surfaces for this example were generated without using any decimation or smoothing in the ModelMaker module.]]<br />
