The cool thing is that it's not a compression algorithm so you could use both. TinyJPG to compress the smaller-sized image, RAISR to upsample the smaller image.

- derefr 10y agoNow create a psychophysical compressor that optimizes for the weighted combination of smallest compressed size and most-faithful RAISR restoration. I wonder if there's a guaranteed-optimal way to do that, given whatever RAISR is using as an algorithm; some logical inverse to the particular way it adds information. Maybe truncated wavelet compression?
