Spectral Indexing

Spectral indexing allows users to apply mathematical functions to spectral indices/bands, which can reveal specific characteristics or anomalies within images.

Using Spectral Indexing:

1. Enter channel expressions for the Red, Green, and Blue channels in the text boxes (e.g., ch[50], ch[100]*2, ch[25]/ch[10]).

2. Press Enter or click "Compute" to generate the images.

3. Images with invalid indices will be skipped, and a warning will be displayed.
