Dual-Branch Task Residual Enhancement with Parameter-Free Attention for Zero-Shot Multi-label Image Recognition

Zero-shot multi-label image recognition involves the task of recognizing multi-label images while “zero” visual information has been input into the model during training. Recently, with the emergence of large pre-trained vision-language model, the visual and semantic features can be well aligned after being trained with billions of image-text pairs collected from the internet. In this paper, by utilizing the pre-trained CLIP model, we propose a dual-branch task residual enhancement with parameter-free attention module that enhances interaction of inter-modal information to tackle the problem of multi-label image recognition. The method employs a dual-branch structure, including global and local branches. The local branch mitigates global feature dominance, improving image content understanding ability of local regions. Our method shows superiority in zero-shot multi-label learning on VOC2007, MS-COCO, and NUS-WIDE datasets, surpassing the state-of-the-art methods. Additionally, it also has excellent performance in partial label settings. Code is available in the supplementary materials.
