Hyperspectral Viewer

Visualize hyperspectral and multispectral data

Description

Add-On Required: This feature requires the Hyperspectral Imaging Library for Image Processing Toolbox add-on.

The Hyperspectral Viewer app visualizes hyperspectral and multispectral data, enables you to create spectral profiles of points and regions in the data, plot endmembers, compute spectral indices, and export results.

Note

The Hyperspectral Imaging Library for Image Processing Toolbox™ requires desktop MATLAB^®, as MATLAB Online™ and MATLAB Mobile™ do not support the library.

Open the Hyperspectral Viewer App

• MATLAB Toolstrip: On the Apps tab, under Image Processing and Computer Vision, click the Hyperspectral Viewer app icon.

• MATLAB command prompt: Enter hyperspectralViewer. For more information, see Programmatic Use.

Examples

Open Hyperspectral Viewer

Construct a hypercube object with the Indian Pines hyperspectral data set.

hcube = imhypercube("indian_pines.dat");

Open the Hyperspectral Viewer app with the Indian Pines data.

hyperspectralViewer(hcube);

Programmatic Use

hyperspectralViewer opens the Hyperspectral Viewer app.

hyperspectralViewer(spcube) opens the Hyperspectral Viewer app, loading the hypercube or multicube object spcube into the app. If spcube is a multicube object and it does not have uniform resolution across all spectral bands, the app chooses the resolution of one of the spectral bands and resamples the all the bands to the chosen resolution.

hyperspectralViewer(spcube,resolution) opens the Hyperspectral Viewer app, loading the multicube object spcube into the app after resampling all the bands to the resolution specified by resolution. The input argument resolution must be the resolution of one of the spectral bands of the multicube object spcube. (since R2025a)

hyperspectralViewer(cube) opens the Hyperspectral Viewer app, loading the 3-D array cube. When not loading a hypercube or multicube object, the capabilities of the app are limited.

hyperspectralViewer close closes all open Hyperspectral Viewer apps.
