How to handle IHS-RGB transformations
This page presents the procedures to operate "IHS_RGB Transformation..." window.
Learn more about IHS transformation in SPRING
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.
