TiledWan Image Statistics

Sometimes the node you need does nothing but talk. TiledWan Image Statistics takes an image, prints min, max, mean, variance, and median to your ComfyUI console, and passes the image straight through. That's the whole job, and it's a genuinely handy one when you're debugging a video pipeline.

It ships in Baverne's comfyUI-TiledWan pack, whose real business is tiled Wan 2.1 VACE video inpainting - but debugging utilities like this are why the pack is a set rather than a single node. Where it earns its keep: checking whether an image is properly normalized before it hits a model, catching a near-black or near-white frame that would silently wreck a batch, or verifying that a channel actually spans the range you think it does. The stats land in the console because the node is an output node by design - it's a diagnostic, not a data source.

Inputs: image (IMAGE) and show_per_channel (BOOLEAN, on by default), which adds separate R/G/B breakdowns to the console output. Outputs: the image pass-through plus five FLOAT values - min_value, max_value, mean_value, variance, median_value - in case you want to wire a threshold somewhere.

It's useful precisely because it's boring: no knobs to mis-set, no failure modes to hit. Install it as part of the pack - ComfyUI Manager (search "comfyUI-TiledWan"), or cd ComfyUI/custom_nodes && git clone https://github.com/Baverne/comfyUI-TiledWan, then restart - and it just works. The pack declares no extra dependencies.

If your problem is masks rather than images, the pack's TiledWan Mask Statistics is the sibling for that.
