See Finer, See More: Implicit Modality Alignment for Text-based Person Retrieval. (arXiv:2208.08608v2 [cs.CV] UPDATED)

Text-based person retrieval aims to find the query person based on a textual
description. The key is to learn a common latent space mapping between
visual-textual modalities. To achieve this goal, existing works employ
segmentation to obtain explicitly cross-modal alignments or utilize attention
to explore salient alignments. These methods have two shortcomings: 1) Labeling
cross-modal alignments are time-consuming. 2) Attention methods can explore
salient cross-modal alignments but may ignore some subtle and valuable pairs.
To relieve these issues, we introduce …
