Generative AI Image Toolset with GANs and Diffusion for Real-World Applications

JoliGEN is an integrated framework for training custom generative AI image-to-image models

Main Features:

• JoliGEN implements both GAN and Diffusion models for unpaired and paired image to image translation tasks, including domain and style adaptation with conservation of semantics such as image and object classes, masks, ...

• JoliGEN generative AI capabilities are targeted at real world applications such as Controled Image Generation, Augmented Reality, Dataset Smart Augmentation and object insertion, Synthetic to Real transforms.

• JoliGEN allows for fast and stable training with astonishing results. A server with REST API is provided that allows for simplified deployment and usage.

• JoliGEN has a large scope of options and parameters. To not get overwhelmed, follow the simple Quickstarts. There are then links to more detailed documentation on models, dataset formats, and data augmentation.

Use cases

• AR and metaverse: replace any image element with super-realistic objects
• Image manipulation: seamlessly insert or remove objects/elements in images
• Image to image translation while preserving semantics, e.g. existing source dataset annotations
• Simulation to reality translation while preserving elements, metrics, ...
• Image generation to enrich datasets, e.g. counter dataset imbalance, increase test sets, ...

This is achieved by combining powerful and customized generator architectures, bags of discriminators, and configurable neural networks and losses that ensure conservation of fundamental elements between source and target images.
