JoliGEN: A Generative Image-Video Conversion Framework for Real-World Scenarios

JoliGEN is an integrated generative AI framework that supports GANs, diffusion models, and consistency models, focusing on image-to-image translation tasks. It has a clear positioning: to build a toolset for practical applications, bridging the gap between academic research and industrial deployment. Its core advantage lies in enabling practical applications such as domain adaptation, style transfer, and object insertion while maintaining semantic consistency.

Generative AI has made significant progress in image processing, but many open-source tools remain in the research demonstration phase and struggle to meet the complex needs of the real world. JoliGEN is positioned to build a generative AI toolset for practical image and video applications, bridging the gap between academic research and industrial deployment.

JoliGEN's core technical features include:

1. Multi-model Architecture Support: Supports GANs, diffusion models, and consistency models simultaneously. Users can choose the appropriate generation paradigm based on tasks, covering scenarios from fast inference to high-quality generation.
2. Semantic Consistency Preservation: A core advantage distinguishing it from other tools—maintains semantic information such as image and object categories and masks during domain adaptation or style transfer (e.g., labels for elements like vehicles and pedestrians remain valid when converting day to night).
3. Paired and Unpaired Translation: Supports both paired (e.g., color to grayscale) and unpaired (e.g., photo to oil painting) training modes.
4. Controllable Generation Capability: Users can finely control the generation process, including specifying reserved areas, adjusting the degree of style transfer, and local editing.

JoliGEN's application scenarios include:

• Augmented Reality (AR) and Metaverse: Seamlessly integrate virtual objects into real environments while maintaining consistency in lighting, shadows, and perspective.
• Image Editing and Content Generation: Place products in different backgrounds in e-commerce scenarios, or remove unwanted elements in post-photography.
• Domain Migration from Simulation to Reality: Convert synthetic images to real-world styles in autonomous driving and robot training, bridging the gap between simulation and reality.
• Intelligent Dataset Augmentation: Generate diverse variants to balance dataset distribution and solve class imbalance issues (e.g., generate rainy or snowy variants from sunny driving data).

JoliGEN's technical implementation highlights:

1. Fast and Stable Training: Optimized for training stability, converges quickly on large-scale datasets, suitable for frequent iterations in industrial applications.
2. REST API Server: Provides an out-of-the-box server deployment solution, simplifying integration into production environments. Developers can call generation capabilities via API.
3. Rich Configuration Options: Supports fine-grained control with numerous parameters. The official documentation provides detailed quick-start guides to help users move from simple cases to in-depth usage.

Effect examples shown in the project repository:

• Virtual Try-On: Diffusion models enable natural clothing try-on while maintaining human pose and lighting consistency.
• Object Insertion: Naturally insert vehicles into road scenes in the BDD100K driving dataset, blending with the environment.
• Style Transfer: Weather and lighting conversions such as day to night, sunny to snowy/cloudy.
• Object Removal: GAN technology removes objects like glasses from images and naturally fills the occluded areas.
• Game Character Conversion: Convert Mario-style characters to Sonic-style while maintaining action pose consistency.

JoliGEN provides comprehensive documentation support:

• Official Documentation Website: https://www.joligen.com/doc/
• GAN Quick Start Guide
• Diffusion Model Quick Start Guide
• Dataset Format Description
• Training Tips and Best Practices

Comprehensive documentation coverage lowers the entry barrier, making it easy for developers from different backgrounds to quickly leverage the framework's capabilities.

JoliGEN represents an important step for generative AI from the laboratory to production environments. It integrates current advanced generative model technologies and conducts systematic engineering optimizations for real-world application scenarios. AR/VR developers, data scientists, and computer vision researchers can all find valuable tools and methods here. As generative AI technology evolves, frameworks like JoliGEN that focus on practical applications will play a key role in more fields.
