(check v1.0 page for comparison images)This is a workflow to strip persons depicted on images out of clothes.

Open the image in SAM Editor (right click on the node), put blue dots on person (left click) and red dots on background (right click). Detect and save to node. Retouch the mask in mask editor. Don't forget to actually use the mask by connecting related nodes!Q: Some hair is not excluded from the mask.A: Find "Detect and cut hair" group and decrease treshold there.Q: Got patches of skin around the face.A: Same as above, plus find "Detect face" group and increase "dilation" there. Connect the correct nodes to choose dilated face mask.Q: Gloves persist.A: Connect correct nodes to not exclude hands.Q: Hanging clothes generated.A: Check your prompt. Put that specific clothes piece into negatives.Q: Skin color mismatch anyway.A: Detect a desired skin color manually in any color picker (Paint works). Put RGB values in "Manual skin color" node.Q: Got seams around former siluette.A: Significantly increase denoise in next to last and last nodes. But it might destroy background.Q: Wrong pose/missing limbs.A: Barely fixable. Should insert manually created OpenPose pose, which is pain.Q: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all().A: Update both ComfyUI and Impact Pack.<a target="_blank" rel="ugc" href="https://civarchive.com/user/Postpos/models">Check out my other workflows</a>
