The «Histogrm» window is used for displaying of the histogram for the entire image of the ROI(s) selected. Index watershed displays on two different images.
For a selected set of reflection spectrum of biological substances it is possible to construct a heat map of its contribution to the reflection spectrum of the obj under study.
The window «Spectral analysis” is designed for displaying of the spectra corresponding to the ROIs selected in the «ROIs» window. Clicking on a spectrum highlights the whole spectrum with bold line and color.
An excellent module for working with a set of spectral channels.
Save channel list, uninterrupted way to watch channels. Creating an index from a spectral channel.
