Expression And Gesture Control With Animation Parameters

via “motion intensity and style control”

LivePortrait — AI demo on HuggingFace

Unique: Implements motion intensity control through learned scaling functions that preserve anatomical plausibility across intensity ranges, rather than naive vector scaling which produces distortion at extreme values, by constraining scaled landmarks to valid facial geometry

vs others: More intuitive than low-level parameter adjustment and more flexible than fixed presets because it provides continuous control with automatic constraint satisfaction, enabling users to explore the full expression space without manual tuning
