>>45768495>>45768794Canny is good for lineart and stuff, where you want the "detail shape" of something, basically tracing.
Openpose is good for full-body images, especially scenes from movies and the like where you want the general idea of a pose but nothing about the background etc.
Depth is your go-to for turning real ass into anime ass, as well as other 3dpd smut conversion uses
HED is my workhorse jack-of-all-trades, great for "redrawing" an image, but needs a lot of fine tuning in its weight.
