Highlights

The goal of this work is to enhance global text-to-image person retrieval performance, without requiring any additional supervision and inference cost. To achieve this, we utilize the full CLIP model as our feature extraction backbone. Additionally, we propose a novel cross-modal matching loss (SDM) and an Implicit Relation Reasoning module to mine fine-grained image-text relationships, enabling IRRA to learn more discriminative global image-text representations.

Usage

Requirements

we use single RTX3090 24G GPU for training and evaluation.

pytorch 1.9.0
torchvision 0.10.0
