What is Hallo?
Hallo is a sophisticated AI model developed by researchers at Fudan University that enables hierarchical audio-driven visual synthesis for portrait image animation. The model creates realistic facial animations by processing audio inputs and applying them to static portrait images, while maintaining high fidelity and natural movement.
Implementation Details
The model utilizes a hierarchical approach to audio-visual synthesis, incorporating advanced diffusion techniques and safetensors for optimal performance. It's implemented with both ONNX runtime support and traditional tensor operations, allowing for flexible deployment options.
