How to handle IHS-RGB transformations

This page presents the procedures to operate "IHS_RGB Transformation..." window.

Performing an IHS transformation:

  • select an image model IL at the "Control Panel" ( );
  • click on Image - IHS<->RGB Transformation ... at the main menu;
  • choose at the option IHS<->RGB Transform... the desired option (RGB->IHS, IHS->RGB, RGB->Image, IHS->Image);
  • in Input Images inform which bands will take part in the transformation (R, G, and B or I, H and S). Use the window "Categories and ILs" to insert the input ILs you will use ( learn more about this window); click on the list of categories and choose an IL; click again in Apply. Observe that the selected IL and the resolution are presented;
  • in Output Layer: type the name of the output image. This name will be used as a prefix to generate the output images. For example, for a RGB-IHS transformation and Output Layer named "Trans1", the outcome will be: "Trans1_I, Trans1_H e Trans1_S". For a RGB-Image transformation and output layer "Trans2", the outcome will be "Trans2_C";
  • in Output Resolution choose on of the three options. It is not necessary to type the value because the resolution can only be the same as the images used as input (I, H and S or R,G and B);
  • set number of bits for the Output image.
  • click on Apply to perform the transformation.

NOTE: Notice on the "Control Panel" that the outcome images will always be associated to the same category as the input images.
