Imgix is the middle, they process the parameters once and cache the result.

  That is just caching. Middle is: You precompute some fixed presets(like him, lower latency) but also have the ability to generate on demand if a preset doesn't exist(used when adding new presets, no reason to wait *days to have the new preset).

    Once you've built a system that works fast enough to handle image rendering work on-demand, then adding batch or precomputational features is largely just creating requester logic to ask for the image before the real demand arrives.
