Object-wise classification, utilizing majority voting after zero-shot segmentation, consistently improves overall accuracy across all models. MFT (Multimodal Fusion Transformer) achieves the highest performance by effectively leveraging both RGB and HSI features.
Understand the limitations of current approaches and proposed directions for future research, including refined input tokenization, architectural enhancements, and data engineering strategies.
Addressing Object Segmentation Limitations
Overlapping Objects: A Challenge for Zero-Shot Segmentation
The study reveals that object-wise classification via majority voting can fail when zero-shot models misinterpret overlapping or touching objects as a single instance. This limitation highlights the need for fine-tuning large pre-trained models on domain-specific annotations to accurately define object boundaries.
Key Takeaway: Domain-specific fine-tuning is crucial for zero-shot segmentation models to effectively handle complex real-world scenarios in recycling streams, improving classification robustness by correctly identifying individual material fragments.
