Spectral Mapping

 

2D-Spectrum You can group segments not only in the source image, but also in its spectral mapping. Each segment has its own small ball on a two-dimensional spectrum. The size of the ball matches the size of the segment.

Holding "Ctrl" and the left mouse button, you can select the balls and their corresponding segments. The right mouse button cancels the selection. The cursor size can be changed using "Ctrl+Alt" and the mouse wheel. A convenient way to select similarly colored balls is to rotate the mouse wheel Up/Down, pressing "Ctrl".

The selected balls are highlighted. They can be moved with the mouse, changing the color of the corresponding segments of the image. Balls can be grouped. But you can also change the color for the current spectral selection without grouping.
