LVCD
Overview :
LVCD is a reference-based line art video coloring technology that employs a large-scale pre-trained video diffusion model to produce colored animated videos. This technology utilizes Sketch-guided ControlNet and Reference Attention to achieve coloring for fast and large movements in animated videos while ensuring temporal coherence. The main advantages of LVCD include maintaining temporal coherence in colored animated videos, effectively handling large movements, and generating high-quality output results.
Target Users :
LVCD is ideal for animators, video editors, and visual effects specialists, as it provides an efficient and high-quality video coloring solution, particularly for animation videos that involve complex movements and demand temporal coherence.
Use Cases
Coloring line art from the animated film 'Spirited Away'
Colorization treatment for the animated film 'Big Fish & Begonia'
Dynamic scene colorization for the animated short film 'Mr. Cat'
Features
Sketch-guided ControlNet: A control network guided by line art, providing additional control for video composition.
Reference Attention: Facilitates color transfer from reference frames to other frames, handling rapid and extensive motion.
Overlapped Blending Module: A module for overlapping blending, designed for long video coloring.
Prev-Reference Attention: A mechanism to maintain temporal coherence in long video generation.
Large-scale pre-trained video diffusion model: Generates colored animated videos using a large-scale pre-trained model.
Temporal coherence enhancement: Improves temporal coherence in video coloring through sequence sampling and attention mechanisms.
High-quality output: Creates animated videos with high frame and video quality.
How to Use
1. Prepare the line art video and reference frames
2. Use Sketch-guided ControlNet for initial coloring
3. Apply Reference Attention for color transfer
4. Utilize the Overlapped Blending Module for coloring long video sequences
5. Ensure temporal coherence using Prev-Reference Attention
6. Fine-tune the model to adapt to specific animation styles
7. Generate the final colored video using a pre-trained video diffusion model
8. Evaluate and adjust the coloring results to meet quality standards

Animate Anyone
Animate Anyone aims to generate character videos from static images driven by signals. Leveraging the power of diffusion models, we propose a novel framework tailored for character animation. To maintain consistency of complex appearance features present in the reference image, we design ReferenceNet to merge detailed features via spatial attention. To ensure controllability and continuity, we introduce an efficient pose guidance module to direct character movements and adopt an effective temporal modeling approach to ensure smooth cross-frame transitions between video frames. By extending the training data, our method can animate any character, achieving superior results in character animation compared to other image-to-video approaches. Moreover, we evaluate our method on benchmarks for fashion video and human dance synthesis, achieving state-of-the-art results.
