DeepSUM: Deep neural network for Super-resolution of Unregistered Multitemporal images (ESA PROBA-V challenge)
May you provide 'dataloader' and 'utils'?
Thanks
Hi,
Great work ! I am interested in components of deepsum (specifically finding features in a wide array of datasets, and then aligning them all together).
Just before digging in more, I would like to have high level advice on how easy or hard that would be and what caveats should I have in mind.
P.S. i do not have any prior experience in machine learning, so I might be doing a lot of back and forth from here onwards.
My first question is :
Should the images to be registered have no geo-information to begin with ?
Thanks

Now I want to pre-train the RegNet with sentinel-2 and SPOT images. But I don't know how to pre-train RegNet without knowing the ground truth.
In your paper, it said
The input data to be used for the pretraining of RegNet
are the feature maps produced by the pretrained SISRNet for
the images in the training set.
Then the next sentence is
As described in Sec. IV-B, the input to RegNet are N feature maps from images of the
same scene. These feature maps are then synthetically shifted with respect to the first one by a random integer amount of pixels. The purpose is to create a balanced dataset where all
possible K 2 classes (shifts) are seen by the network. The desired output is a filter with all zeros except for a one in the position corresponding to the chosen shift.
I don't really understand this part. Where do I get the random integer amount of pixels from? If it's random, does it mean the ground truth is a random vector with a component being 1 and the rest are 0?
My question is what is ground truth data when pretraining the RegNet?
Thank you.
