ShapeWorks Studio Groom Module
The Groom module provides options to preprocess/groom the input data. Options differ for binary segmentations and meshes. You also have the option of skipping grooming if your data is already prepped.
Image Grooming Parameters
| Parameter | Description |
|---|---|
| Isolate | Isolate the largest object in a segmentation. This removes extraneous noise voxels that would result in disjoint objects. |
| Fill Holes | Fill small holes in segmentation |
| Crop | Crop image down to ROI of segmentation |
| Pad | Pad image with zeroes by a given number of voxels. Typically combined with cropping |
| Antialias | Perform anti-aliasing to reduce segmentation stairstep effect |
| Resample | Resample image spacing either to isotropic (recommended) or any given spacing |
| Distance Transform | Create a distance transform for image based optimization |
| Blur | Perform smoothing on the distance transform using a gaussian blur |
| Convert to Mesh | Optionally convert to mesh at the end of Image Grooming. This enables the Mesh Grooming pipeline and will run the optimization on meshes |
Mesh Grooming Parameters
| Parameter | Description |
|---|---|
| Fill Holes | Fill small holes in the mesh |
| Smooth | Perform either Laplacian or Windowed Sinc smoothing |
| Laplacian Smoothing | Laplacian smoothing option with specified iterations and relaxation factor. In general, it is recommended to use smaller relaxation factors and more iterations rather than larger relaxation and fewer iterations |
| Windowed Sinc Smoothing | Windowed Sinc smoothing with specified iterations and passband (typically between 0 and 2). Lower passpand values produce more smoothing. |
| Remesh | Enabled remeshing using ACVD library |
| Remesh Percent | Specify target vertices as a percentage of existing vertices |
| Remesh Vertices | Specify target vertices directly |
| Remesh Adaptivity | Curvature adaptivity of remeshing (0 = uniform, 2.0 most adaptive). This allocates more triangles/vertices to areas of higher curvature |
Alignment Parameters
| Parameter | Description |
|---|---|
| Reflect | Option to reflect some shapes over a given axis if a given column matches a given value (e.g. reflect 'side' over 'Y' if 'left') |
| Alignment | Option to align with centering (center of mass), iterative closest point (translation and rotation), or landmarks (best fit, when specified) |
