REV Estimator
Free IPSDK Explorer plugin to guide you in definig your Representative Elementary Volume (REV / RVE).
General description
The Representative Elementary Volume (REV) (also called Representative Volume Element (RVE) or Unit Cell) is the smallest volume over which a measurement can be made that will yield a value representative of the whole.
IPSDK Explorer free-of-charge REV Estimator plugin enables you to automatically determine the optimal dataset size you need to use to save computing time and workstation requirements costs without impacting the final result.
Based on robust image processing techniques, the REV Estimator plugin analyzes all possible blocks of a given size using a linear sliding block technique on entire dataset.
The statistics are then used to determine the standard deviation from the block density..
IPSDK optimized implementation provides a robust and noise-free REV estimation.
Achieve the optimum size: the right balance between compactness and reliability, tailored to your criteria.
As output of this plugin, you will obtain your optimal size, defined as the smallest block that meets statistical stability in accordance with the threshold you specify.
The REV Estimator plugin is particularly relevant for any type of dataset application (histology, rock analysis, composite materials…) to
- determine Mechanical properties
- understand Porous media structures
- generate Simulation inputs
No need to be an Image Analysis expert to dettermine your dataset REV.
Once your settings are defined and stored, you can use them automatically as a “press button application” image per image or using batch processing on every image in a folder.
The REV Estimator Plugin interface can be used to select a binary image from a preliminary segmentation (manual or automatic).
The supported images can be either 2D or 3D.
The configuration window helps you to precisely adjust the analysis parameters according to the size of your dataset together with a maximum variability applicable to your analysis:
- Block size range
- Step blocks
- Standard deviation maximum target
Once your settings are defined and stored, you can use them automatically as a “press button application”.
Last but not least: the Python code behind this plugin is available. You can modify it if needed or integrate it into a Python script. For more information concerning this plugin, please read our User Guide.
