AI Artifact Removal

AI-based removal of JPEG compression artifacts, blocking, and ringing. Automatic detection mode applies removal only when artifact severity is above the activation threshold.

Requires: NVIDIA GPU for production throughput. CPU mode is available but significantly slower.

Parameters

Parameter	Section	Value	Default	Description
ARmode	Config	0 – 8	2	Mode selection (see below)
arstrength	Gpars	0.0 – 1.0	0.5	Activation threshold — higher value only triggers on more severely degraded images

Modes

Value	Description
0 — Off	No artifact removal
1 — Auto, CPU	CPU-only DCT smoothing when artifacts detected
2 — Auto with AI (default)	Detects artifact severity, selects appropriate AI model
3 — Auto with AI, fast	Faster variant of Auto with AI
4 — Always CPU	Unconditional CPU-based DCT smoothing
5 — Always AI	Unconditional full-quality AI removal
6 — Always AI, fast	Unconditional fast AI removal
7 — Always CPU + AI	Combined CPU and AI passes
8 — Always CPU + AI, fast	Faster combined CPU and AI

Recommended: Mode 2 (Auto with AI) for general production. Use modes 5 – 8 only when you know every input has heavy compression artifacts.
