Define cell boundaries with Membrane-based Segmentation

Finding cell boundaries based on membrane-localized contrast is made many times easier by new algorithms that enhance membranes in 3D and an operator designed to segment cells in 3D.

This new workflow allows use of any image filters upstream of the Membrane-based Segmentation, which enables optimization of results and/or application to challenging images.
Users can select between Membrane Enhancement and Objectness Measure (sheets) filters depending on data quality and time constraints. Membrane Enhancement gives the highest quality but takes longer while Objectness Measure computes faster. All the other filters in arivis Vision4D (Morphology, Denoising, etc.) are at the users disposal for fine tuning.
The Membrane-based Segmentation is adjusted interactively to increase cell segmentation yield and “over splitting” is easily proof-edited with the Merge tool.

Enhance your membrane stains

Find out how you can enhance your membrane stains with arivis Vision4D

 

Step 1

Determine the width of membranes

Measure the width of membranes and optimize the voxel filters in your pipeline.

Step 2

Optimize the Membrane-based Segmentation

Adjust the Threshold to define the borders of cells and tune the sensitivity to increase or decrease 3D splitting of cells.

Optimize the Membrane-based segmentation

 

Step 3

Edit segmentation objects

Edit segmentation objects

 

Fix over-splitting via the Merge Objects tool.

Work with the results

The Objects database in arivis Vision4D calculates measurements based on the segmented objects. You can highlight individual or groups of cells interactively in the Objects table, or  in the 2D / 4D Viewers.
Measure and sort by myriad features such as volume, sphericity, mean intensity and more.
Export the relevant measurements to Excel or CSV for any other software for additional analysis.
