ComfyUI Temporal Mask Tools

Temporal-mask cleaning tools for ComfyUI: union noisy frames to smooth flicker, then drop one-off specks so your mask sequences stay stable.

Nodes

Temporal Mask Union (TemporalMaskUnion)

Combines nearby frames in a temporal mask sequence to suppress flicker.

Input	Type	Default	Notes
mask_batch	MASK	required	Accepts (frames, H, W), (batch, frames, H, W), or (H, W) tensors.
radius	INT	2	Temporal half-window size.
mode	STRING	"or"	"or" keeps any active frame, "majority" uses the threshold.
threshold	INT	3	Minimum active frames within the window when mode="majority".

Temporal Mask Remove Short Objects (TemporalMaskRemoveShortObjects)

Drops one-frame flicker or tiny specks by combining per-frame connected-component filtering with temporal run-length pruning.

Input	Type	Default	Notes
mask_batch	MASK	required	Supports (H, W), (frames, H, W), (batch, frames, H, W) tensors.
min_duration	INT	2	Minimum consecutive frames required to keep a pixel active.
min_area_pixels	INT	10	Connected components smaller than this pixel count are removed.

Usage

1. Clone into ComfyUI/custom_nodes and restart ComfyUI.
2. Drop the desired node into your graph and connect it to a mask sequence batch.
3. Optional: enable node-level debug_output (when available) while tuning parameters.
