Automated Damage Detection

Prototype for automated damage detection in Sentinel 1 imaging of iceselves using unsupervised learning.

The prototype makes use of a VAE architecture, and employs a bespoke input genertation framework to create cutouts for network training from larger imaging tiles.
Notebooks have been used for intial prototyping. These have been converted to scripts for a first production prototype.

Within each directory another README file is included provide more details

• files : contains list of data tiles used for training/testing
• notebooks : contains python notebooks for training, pre- and post-processing
• scripts : contains python scripts for traininig, pre- and post-processing
• training: contains one of of the trained VAE models in a .zip, and an overview of the trained models that are available at /projects/0/einf512/trained_models/

Comments

Last analysis (nov2023) concluded that the predcited damage from the trained VAE, applied to Antarctic wide Sentinel-2 data, was very similar to simple threshold on spectral bands (and so the VAE was not able to deduce interesting patterns after all).
