Echomimic
EchoMimic is a multimodal human animation framework and diffusion-based video generator. It produces lifelike facial and semi-body animations of a reference image by synthesizing motion and appearance from various source data.
The system enables portrait animation driven by audio, pose sequences, or driver videos. It features a landmark conditioning tool that allows for the precise control of facial movements by modifying specific landmark points.
The framework covers multi-modal motion synthesis and the synchronization of reference images to match the physical movements of a target driver. This includes the ability to transform audio signals into facial pose parameters to drive generated video frames.
