Filters
The filters category focuses on image-domain operations that preserve a retoucher's core signal: texture, edges, and controllable smoothness. These are the pack's foundational cleanup nodes.
- N-01 GPU Frequency Separation — Splits an image into low-frequency color/form and high-frequency detail.
- N-03 Edge-Aware Skin Smoother — Applies bilateral smoothing with mask-aware blending and device controls.
- N-04 High-Frequency Detail Masker — Builds high-frequency protection masks for retouch and inpaint passes.
Flagship pages: N-29 Alpha Matte Extractor, N-33 Mask Edge Smoother, and N-10 Face Detect.
