Panoptic segmentation, combining semantic and instance segmentation, stands as a cutting-edge computer vision task. Despite recent progress with deep learning models, the dynamic nature of real-world applications necessitates continual learning, where models adapt to new classes (plasticity) over time without forgetting old ones (catastrophic forgetting). Current continual segmentation methods often rely on distillation strategies like knowledge distillation and pseudo-labeling, which are effective but result in increased training complexity and computational overhead. In this paper, we introduce a novel and efficient method for continual panoptic segmentation based on Visual Prompt Tuning, dubbed ECLIPSE. Our approach involves freezing the base model parameters and fine-tuning only a small set of prompt embeddings, addressing both catastrophic forgetting and plasticity and significantly reducing the trainable parameters. To mitigate inherent challenges such as error propagation and semantic drift in continual segmentation, we propose logit manipulation to effectively leverage common knowledge across the classes. Experiments on ADE20K continual panoptic segmentation benchmark demonstrate the superiority of ECLIPSE, notably its robustness against catastrophic forgetting and its reasonable plasticity, achieving a new state-of-the-art.

2024-04-29 First Commit, We release the official implementation of ECLIPSE.

Our implementation is based on CoMFormer and Mask2Former.

Please check the installation instructions and dataset preparation.

You can see our core implementation from

• mask2former/maskformer_model.py
• mask2former/modeling/transformer_decoder/mask2former_transformer_decoder.py

1. Step t=0: Training the model for base classes (you can skip this process if you use pre-trained weights.)
2. Step t>1: Training the model for novel classes with ECLIPSE
