I was doing change detection using ERDAS Imagine DeltaCue wizard mode for the years 2016 and 2018 which were aquired from World-view 2, preprocessd in the same way upto pan-shaprpening and subsetting. However, when I insert the images it says: "imput images have diffrent image sizes" look the image below, as a result I couldn't do the change detection. As far as I know, the two images have a very small pizes size diference (like 1.88.. and 1.9 around but not sure. If you want I will let you know). So, could you suggest me any solution either editing/matching the pixel sizes or any other technique to finish my task using DeltaCue technique?
Thank you so much for your usual suggestions!

You will need to resample one image so that the pixel size matches for both images before selecting them as the inputs for IMAGINE DeltaCue. You can use the Resample tool to perform this task. Open one of the images in the Image Metadata tool first and record it’s exact X and Y pixel size so that you know the precise pixel size to enter for the other image in the Resample tool.
