N-01 GPU Frequency Separation

JHPixelProFrequencySeparation separates form/color from detail by producing a blurred low layer and a signed high layer. It is the pack's base texture-retouch node for rebuildable frequency-separation chains.

Schema

Name Kind Type / default Description
image Input IMAGE Source image in ComfyUI BHWC format.
radius Widget INT, default 8 Gaussian blur radius in pixels.
sigma Widget FLOAT, default 0.0 Sigma override; 0.0 auto-derives sigma from radius.
precision Widget COMBO, default float32 Uses float32 for exact reconstruction or float16 for GPU speed.
low Output IMAGE Low-frequency color and form layer.
high Output IMAGE High-frequency detail layer.
