What is MEMO?
MEMO (Memory-Guided Diffusion) is a cutting-edge AI model designed for generating expressive talking video content from a single image and audio input. The model leverages advanced diffusion techniques combined with memory-guided mechanisms to create realistic and emotionally expressive facial animations.
Implementation Details
The model operates using a sophisticated pipeline that processes both image and audio inputs, utilizing CUDA-enabled GPUs for efficient processing. Under default settings (30 fps, 20 inference steps), it achieves impressive processing speeds of approximately 1 second per frame on H100 and 2 seconds per frame on RTX 4090.
