Handle nodata or other ignore values in raster data sets #58

Open hannah-rae opened 3 years ago

hannah-rae commented 3 years ago

Rasters often have nodata values that should be ignored in analysis (e.g., edges missing data due to registration). These pixels should be given a specific sentinel value (e.g., -9999) instead of being scored.

@bdubayah Have you made this change for the raster pixel loader too? Are you planning to PR/merge or are you still making changes?

bdubayah commented 2 years ago

Still need to do it for raster pixels. I think we also need to decide the merge strategy for overlapping patches - whether to stick with mean or do max instead. I'm going to try with max for the vtfs experiment and see how it works out.
