DiffusionInst: Diffusion Model for Instance Segmentation

DiffusionInst is the first work of diffusion model for instance segmentation. We hope our work could serve as a simple yet effective baseline, which could inspire designing more efficient diffusion frameworks for challenging discriminative tasks.

Todo list:

• Release source code.
• Hyper-paramters tuning.
• Add Swin-Large backbone.
• Release trained models.
• Adding directly filter denoising.

Getting Started

The installation instruction and usage are in Getting Started with DiffusionInst.

Trained Models

We now provide trained models for ResNet-50 and ResNet-101.
