[SLS-DC] CCSDS Data Compression Working Group Spring 2024 TEAMS meeting information

[Aniello Fiengo]

Dear colleagues,

Unfortunately, I won't be able to join you as the time shift is a bit complicated to handle.
However, there are a couple of things I'd like to share with you.

First, I had a discussion with the people from CHIME, they are collecting a dataset for the cloud detection algorithm with cloud masks that will be used to test the "multiclass" (only 2 classes for CHIME) compression. They are willing to share with us the dataset with both the cloud images and the cloud masks once ready.

Also, in CHIME we have discussed the use of some additional metrics for the compression that could be of interest for the 123B3 green book:

  *   The covariance between input and ouput
  *   The crosscorrelation between input and compression error
  *   The crosscorrelation between output and compression error
We had an intern working on compression using the 123B2 with different preprocessing and the Generalised Anscombe Transformation and those metrics were quite insightful, it could be worthed to consider them.

I wish you all a good meeting, I'll try to keep track of the discussions through email.

Best regards,
Aniello
