Just received the final proofs for the 5th Ed. of my monograph on Image Analysis (CRC Press T&F, 2025). The accompanying software (Jupyter notebooks) is already on github.com/mortcanty/CR... and can be run from a Docker container. You can even query the contents with an LLM/RAG if you like.

Just for fun, and because it's "in", I added a LLM/RAG notebook to query the textbook's content informally. Here's poor old Deepseek trying to understand what I want:

The color-coded frequency (or total number) of changes at the port of Odessa, as detected with S1 A and S1 B SAR for the period Jan, 2021 to Aug, 2022 (80 images). Water surfaces are always noisy due to wave effects. Therefore the minimum frequency displayed was set to 5 significant changes.

Ukraine, June 2023, the Kakhovka Dam is breached causing draining of the Zaporizhzhia nuclear power plant's main water source, the Kakhovka Reservoir, about 150 km upstream. This S1 change image shows in red the reduction in VV, VH reflectance. The Dnieper is still connected to the cooling pond.

Sentinel-1C was just launched so let's hope that high frequency, weather independent observations can continue. Here for fun is another time series of changes in Sentinel-1
radar reflectance, this time from a high school parking area in Houston, Texas from Nov, 2017 through July, 2020.
