Statistical Analysis

About

Ultraliser integrates a collection of analysis subroutines for analyzing and evaluating the qualities of meshes, morphologies and volumes.

Surface Mesh Analysis

The mesh analysis code is implemented based on the metrics described in the The Verdict Geometric Quality Library. These metrics are used to evaluate the structure of the mesh and are strongly tied to the accuracy of the simulations that use the resulting meshes. We also implemented another set of subroutines for quantiative analysis.

• Number of triangles in the mesh
• Number of vertices in the mesh
• The size of the mesh in kBytes and MBytes.
• The bounding volume (or dimensions) of the mesh, defined by pMin and pMax.

Distributions

• Triangle area
• Triangle aspect ratio
• Triangle edge ratio
• Triangle minimum angle
• Triangle maximum angle
• Triangle shape
• Triangle condition
• Triangle distortion

Morphology Analysis

Neurons

• Number of samples in the morphology
• Number of sections in the morphology
• Number of segments in the morphology

NOTE: Complete analysis can be doen relying on NeuroMorphoVis and NeuroM.

Vasculature

1. Number of samples (or vertices) in the network
2. Number of strands (or segments) in the network
3. Number of sections (or branches) in the network
4. Total network length

NOTE: Complete analysis can be done relying on VessMorphoVis.

Astrocytes

Number of endfeet

NOTE: Complete analysis can be done relying on NeuroMorphoVis.

Volume Analysis

1. Volume dimensions, i.e. width, height and depth.
2. Number of voxels.
3. Total volume.
4. Voxel dimensions.
