Volume Segmenter

Segment 3-D grayscale or RGB volumetric images

expand all in page

Description

The app can be used to create and refine a binary or semantic segmentation mask for a 3-D grayscale or an RGB image using automated, semi-automated, and manual techniques.

Note

The app is not supported in MATLAB® Online™. For details, see Specifications and Limitations.

Note

Medical Image Labeler (Medical Imaging Toolbox) is recommended over Volume Segmenter because it offers several advantages, such as:

  • Use of spatial referencing information found in file metadata.

  • Simultaneous display of three orthogonal cross-sections.

  • Improved performance.

Medical Image Labeler requires Medical Imaging Toolbox™.

Volume Segmenter app

Open the Volume Segmenter App

  • MATLAB Toolstrip: Open the Apps tab, under Image Processing and Computer Vision, click the Volume Segmenter app icon.

  • MATLAB command prompt: Enter volumeSegmenter.

Examples

Load a volume into the workspace.

load(fullfile(toolboxdir("images"),"imdata","BrainMRILabeled", ...
    "images","vol_001.mat"));

Load the corresponding labeled volume into the workspace. 

load(fullfile(toolboxdir("images"),"imdata","BrainMRILabeled", ...
    "labels","label_001.mat"));

Open Volume Segmenter specifying both the volume and the labeled volume.

volumeSegmenter(vol,label)

Programmatic Use

volumeSegmenter opens the Volume Segmenter app.

volumeSegmenter(V) opens the Volume Segmenter app, loading the volume V into the app. Volume V is an m-by-n-by-p or m-by-n-by-p-by-3 image of data type uint8, uint16, uint32, int8, int16, int32, single, or double.

volumeSegmenter(V,L) opens the Volume Segmenter app, loading the volume V and the labeled volume L into the app. The labeled volume L is an m-by-n-by-p image of data type logical, categorical, uint8, uint16, uint32, int8, int16, int32, single, or double.

volumeSegmenter(___,Show3DDisplay=TF) logical value that specifies whether Volume Segmenter includes a visualization of the 3-D volume in the app. The default value is true. Hiding the 3-D display by specifying Show3DDisplay as false can improve app performance on platforms with limited graphics support, such as Linux platforms or Windows platforms that use software rendering.
