Image 'quality' filter

[globalshrug]

I'm wondering if an image quality filter is viable.

I've noticed that quality can't really be nailed down to any of resolution, file size, or bitrate, with some exceptions. But a high-resolution low-bitrate image can still "look good", if the resolution is high enough that your eye doesn't notice the grain introduced by low bitrate.

And obviously different compression algorithms basically render filesize a useless metric to gauge quality, without at least considering the format and resolution. I'm wondering if it's possible to create page with some sliders (bitrate, file size, resolution) and show which images would be accepted or rejected based on the selected slider positions, for a given bulk image import?

With the next logical step being to accept the parameters and lock those in for "this import" or "all imports" in place of the importer min filesize/resolution settings. I find those to be a bit inflexible.

Another thought on this: replacing the importer criteria with a normal search filter page.

E.g. when importing, let me pull up a filter page, but populate it with all the same controls everyone is used to: a "search" page. But this one controls the import itself. You can put in e.g. "system:filetype = image" and "system:filesize > 1mb" to import only images that are > 1mb. Build out the import you want on the fly and be able to save it as a template or as the default set to use for future imports.

There would have to be an additional section to choose what to do with files that didn't pass the filter. E.g. move them to some folder, delete them, leave them but don't import them, etc.
