Intro: Finesse raw vs segmented images

[donovanr]

Issue summary

decide how to handle raw vs seg as interesting or not.

Details

I think the emphasis on raw image vs. segmentation input in the current introduction is a red herring. First, not all feature extraction requires segmentation (e.g. very few of the hundreds of CellProfiler features do). Second, it would be fine (desirable!!!) to use segmented images as input into the autoencoder, so don’t make it sound like segmentations are bad.

TODO

• [x] manuscript text

[donovanr]

i think the issue can be clarified as

• structure segmentations rather than cell segmentations
• as an issue for image-based generative models, not all models / featurizations

with those caveats, i think the issue stands as one worth mentioning
