I managed to finish Chapter 4 today and will continue with Chapter 3 about finite discrete GA tomorrow. Sure, this might not be done within one week as hoped, and one could think that I’m out of my time plan, but I included the sections about the 4D STFT of 2D signals and (non-)separable 2D windows, what I originally had intended for Chapter 5. The chapter spans 21 pages, and so I’m effectively on page 45 of my thesis.
