I have 5 different years (all in the same month) of Landsat TM imagery to perform classification on and I would like to know whether there is a technique to normalise the pixels in each image so my training sites can remain the same for all 5 images.
I understand this is a common technique to perform multiple-date image normalisation using regression but I am unaware of how to apply the technique.
I am using both
ERDAS Imagine and
Arcmap 10.1 for my analysis.
What tool do I run for this?
