[Feature request] Image preprocessors, e.g. HED, Canny edge, Depth

[jamesWalker55]

I would like to suggest implementing image pre-processors like HED edge detection or depth, these could process images loaded with the LoadImage node. This would be very useful for Controlnet workflows since it automates the generation of control images.

not sure if controlnet loader can suit your need? https://comfyanonymous.github.io/ComfyUI_examples/controlnet/controlnet_example.png

someone made them as custom nodes: https://github.com/Fannovel16/comfy_controlnet_preprocessors

I think it would be awesome to have them already implemented though, as they pretty much go hand in hand with controlnets.

I haven't done HED edge detection but I have depth and canny as stande-alone nodes, no installation steps, just extract and it installs what it needs: https://civitai.com/models/20793

Is HED any good? Honestly only used openpose, depth, and canny

I added edge detection. It's "normal" whatever that is to PIL, and laplacian kernel.

Any good? Hed is the best so far for consistency. I barely use other pp.
