Software Tip | How to Perform Change Detection in ERDAS IMAGINE with DeltaCue

This video walks you through how to use DeltaCue’s wizard interface to perform change detection on two images. In this run through we have used two Landsat 5 tiles of South Wales over the Brecon Beacons National Park.
This is a brief first instalment of tip videos on DeltaCue change detection so please look out for future videos.

Hello Pop,
The change algorithm was selected earlier in the video, this defines how the change is calculated.
The amount of change detection shows how much a feature has changed in spectral response from time 1 to time 2. Therefore, the interactive thresholds define how much percentage change in spectral response you are interested in keeping.
There is lots more information in the ERDAS IMAGINE help documents. The DeltaCue user guide may be particularly useful for this (Help Tab > User guides > DeltaCue user guide)

What could be the problem if a normal graph does not appear in the histogram part, peaks appear and it is impossible to select the lower and upper treshhold

I am doing the LULC of my study area, but I faced some problems, the reflection of false color composition represents two different land use as one, it showed me the same colour that is blue light colour ( for the harvested crop land and urban) and after fishing the site training, the result of supervised classification is not right. the crop land area is replaced by urban. how can I solve it? how can i adjust the reflection of the harvested crop land it look the same with the urban land?

Hello,
I asked a little bit: Why when installing Erdas imagine 2018 software (still installed & cracked for one computer) but when installed on another computer, it is not possible?
Thank you very much

Does upper treshold(yellow) shows what has appeard from time 1 to time 2, and the lower treshold(cyan) shows what disappeard from time 1 to time 2? What is the meaning of the Change Detection Treshold histogram values?
