weight_tool Algorithm band weight

This tab allows for the definition of band weights that are useful for improving the spectral separability of materials at certain wavelengths (bands). During the classification process, band values and spectral signature values are multiplied by the corresponding band weights, thus modifying the spectral distances. A tab is displayed for every Band set.

1.1. Band weight

  • input_table Band weight: table containing the following fields;
    • Band number : number of the band in the Band set;
    • Band name : name of the band;
    • Weight : weight of the band; this value can be edited;

1.2. Automatic weight

  • reset: reset all band weights to 1;
  • Set weight input_number enter: set the defined value as weight for all the highlighted bands in the table;
