That is 42x spatial compression, but it needs 16 channels instead of 3 for RGB.

That is 42x spatial compression, but it needs 16 channels instead of 3 for RGB.
- ansk 3y agoFurthermore, each of those 16 channels would typically be mutibyte floats as opposed to single byte RGB channels. (speaking generally, haven't read the paper)
- zamadatix 3y agoEven assuming 32 bit floats (the extra 4 on the end): 4*16*24*24*4 = 147,456 vs (removing the alpha channel as it's unused here) 3*3*1024*1024 = 9,437,184 Or 1/64 raw size, assuming I haven't fucked up the math/understanding somewhere (very possible at the moment).
- incrudible 3y agoIt is actually just 2/4 bytes x 16 latent channels x 24 x 24, but the comparison to raw data needs to be taken with a grain of salt, as there is quite a bit of hallucination involved in reconstruction.
