New COD-TDQ method boosts quantized Transformer performance for object detection

Researchers have developed a new method called COD-TDQ to improve the performance of Transformer-based models for camouflaged object detection (COD) when using aggressive post-training W4A4 quantization. They identified that heavy-tailed background tokens in COD tasks inflate the activation range, causing crucial boundary cues to be lost. COD-TDQ addresses this by using Direct-Sum Token-Group to suppress range domination and Dual-Constraint Range Projection to maintain bounded step-to-dispersion ratios and zero-bin mass. This approach consistently achieves significantly higher scores on COD benchmarks compared to existing quantization methods without requiring retraining. AI

    When W4A4 Breaks Camouflaged Object Detection: Token-Group Dual-Constraint Activation Quantization

    arXiv:2604.16855v2 Announce Type: replace Abstract: Camouflaged object detection (COD) segments objects that intentionally blend with the background, so predictions depend on subtle texture and boundary cues. COD is often needed under tight on-device memory and latency budgets, m…
