TCAN

Product Details

TCAN is a novel portrait animation framework based on the diffusion model that maintains temporal consistency and generalizes well to unseen domains. The framework uses unique modules such as appearance-pose adaptation layer (APPA layer), temporal control network and attitude-driven temperature map to ensure that the generated video maintains the appearance of the source image and follows the pose of the driving video, while maintaining background consistency.

Main Features

1
Appearance-Pose Adaptation (APPA layer): Maintains the pose information from the frozen control network while maintaining the appearance of the source image.
2
Temporal control network: Preventing generated videos from crashing due to sudden and erroneous pose changes.
3
Pose-driven temperature maps: Reducing flicker in static regions by smoothing attention scores over temporal layers during the inference stage.
4
Temporal consistency: Ensure the continuity of character postures during animation.
5
Generalization ability: Animation generation that can adapt to different fields and identities.
6
Background Preservation: Maintains the consistency of the background of the source image during animation.
7
Multi-identity animation: Able to transfer actions to people or animated characters with different identities.

How to Use

1
1. Prepare source images and driver videos, making sure they contain the desired character appearance and movement.
2
2. Use the TCAN model for portrait animation generation, input source images and driver videos.
3
3. Adjust the parameters in the TCAN model, such as the weight of the APPA layer and the strength of the time control network, to obtain the best animation effect.
4
4. Use attitude-driven temperature maps to reduce flickering and incoherence in animations.
5
5. Observe the resulting animation to ensure that the timing consistency and background remain as expected.
6
6. Make fine adjustments as needed until you achieve a satisfactory animation effect.

Target Users

TCAN is suitable for fields that require high-quality portrait animation generation, such as film production, game development, virtual reality, etc. It is especially suitable for animators who need to achieve complex movements and posture changes while maintaining the consistency of character appearance and background.

Examples

In film production, used to generate character action scenes.

In game development, it is used to create dynamic representations of characters.

In virtual reality, it is used to generate virtual character animations that interact with users.

MIMO

MIMO

MIMO is a universal video synthesis model capable of simulating anyone interacting with objects in complex movements. It is capable of synthesizing character videos with controllable attributes (such as characters, actions, and scenes) based on simple user-provided inputs (such as reference images, pose sequences, scene videos, or images). MIMO achieves this by encoding 2D video into a compact spatial code and decomposing it into three spatial components (main character, underlying scene, and floating occlusion). This approach allows flexible user control, spatial motion expression, and 3D perception synthesis, suitable for interactive real-world scenarios.
