Group Classification


Classify Group classifies different color groups detected on the image, enables defining more appropriate colors and classification of those in homogeneous groups fit for purpose and allows to better distinguish from each other, the objects and limits with reflectance values in similar shades.

In this way, pixels with close brightness (reflectance) values are grouped towards the purpose and new colors are assigned and pixel groups required to be displayed in same group and color are completely classified as user-defined.



If you do not want the class definitions to be reflected on the classified image, use the "Active" option. Class line not wanted to be reflected to the final data can be deactivated with double click.


Name and description of the specified class can be entered.


Color definitions specified for the class are viewed. Color definition can be picked from raster or palette with right click and Select Color.
