| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary A novel approach to prohibited item detection in X-ray images is proposed, building upon the state-of-the-art general object detector DINO. The Anti-Overlapping DETR (AO-DETR) addresses two key issues: feature coupling due to overlapping phenomena and edge blurring. To counteract these challenges, the Category-Specific One-to-One Assignment (CSA) strategy is introduced to constrain category-specific object queries, while the Look Forward Densely (LFD) scheme improves localization accuracy and enhances blurry edge detection. The proposed method provides two distinct versions with tailored backbones for diverse applications. Experimental results on the PIXray and OPIXray datasets demonstrate its superiority over state-of-the-art object detectors, highlighting potential applications in prohibited item detection. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary An AI system can detect forbidden objects in X-ray images by using a new technique called AO-DETR (Anti-Overlapping DETR). This method helps machines identify specific objects that are not allowed in certain places. The problem is that some objects look similar when viewed from different angles or with blurry edges, which makes it harder for the AI to tell them apart. To solve this issue, the researchers came up with two solutions: CSA (Category-Specific One-to-One Assignment) and LFD (Look Forward Densely). These innovations allow the AI to better recognize and locate forbidden objects in images. The proposed method can be used in various security inspection scenarios. |
