Spectrum Viewer

Spectrum Viewer is a quick and easy way to view and interact with hyperspectral data in an image that doesn’t load the entire data into memory enabling it to view very large images.

Spectrum Viewer is available in Breeze as its own tab when viewing a measurement, or as a standalone program you can run without Breeze as a quick way of previewing images.

Features include full-resolution pseudo-RGB display, viewing data in reflectance absorbance and radiances modes, interactive pixel and region-based spectral analysis. Create sub samples by clicking and dragging and compare the spectra. Add sub samples to the Breeze Table for further analysis.

Spectrum Viewer tab for a measurement

Spectrum Viewer is available in Breeze as its own tab when viewing a measurement. Since it does not load the entire image into memory it is quicker to use for large images than the Pixel Explore tab.

If you edit a large image, do not select a too large part of it, as it requires loading everything into memory.
