主题

Compute 3-D Superpixels of Input Volumetric Intensity Image

This example shows how to convert 3-D MRI data into a grayscale intensity image of superpixels.

Explore 3-D Volumetric Data with Volume Viewer App

You can view perpendicular cross-sections of 3-D volumetric data using the Volume Viewer app. Adjust the rendering to reveal structures within the volume.

Explore 3-D Labeled Volumetric Data with Volume Viewer App

You can view 3-D labeled volumetric data using the Volume Viewer app. You can view the volume and the labeled volume simultaneously and change the opacity and color map.

Preprocess Volumes for Deep Learning (Deep Learning Toolbox)

Read and preprocess volumetric image and label data for 3-D deep learning.
