Accuracy of different implem

1 - 10

Lumen

	𝕰𝖒𝖗𝖊 Oh ssimu2rs is less accurate. VSHIP on the other hand can even have better MOS correlation. And the native binary can work on different image types and extensions as a bonus 🙂

2025-06-27 01:12:40	Beware than ffvship can be less accurate than vship because it transmits uint16 instead of float to the gpu

2025-06-27 01:13:22	FFVship is very slightly different from VSHIP.

Lumen

2025-06-27 01:13:45

Usually a bit higher score

𝕰𝖒𝖗𝖊

2025-06-27 01:13:56	I think it's totally worth with the speed benefit.
2025-06-27 01:14:05	If you use the same impl; it doesn't matter for comparison.
2025-06-27 01:14:19	Or for direct quality testing; the margin of difference shouldn't matter anyways

sadly vship is not hardware agnostic which makes it ill suited for my needs.

If only projects like chipstar were more mature...
