The goal of person search is to localize a target person from a gallery set of scene images, which is extremely challenging due to large scale variations, pose/viewpoint changes, and occlusions. In this paper, we propose the Cascade Occluded Attention Transformer (COAT) for end-to-end person search. Our three-stage cascade design focuses on detecting people in the first stage, while later stages simultaneously and progressively refine the representation for person detection and re…

Sequential Transformer for End-to-End Person Search

The proposed SeqTR not only outperforms all existing person search methods with a 59.3% mAP on PRW but also achieves comparable performance to the state-of-the-art results with an mAP of 94.8% on CUHK-SYSU.

SAT: Scale-Augmented Transformer for Person Search

In the three-stage design of the SAT framework, the first stage performs person detection whereas the last two stages performs both detection and re-identification, and introduces separate norm feature embeddings for the two tasks to reconcile the relationship between them in a joint person search model.

The Gallery Filter Network (GFN), a novel module which can efficiently discard gallery scenes from the search process, and benefit scoring for persons detected in remaining scenes, is described and demonstrated.

Deep Intra-Image Contrastive Learning for Weakly Supervised One-Step Person Search

This paper argues that current intra- image contrast is shallow, which suffers from spatial-level and occlusion-level variance, and presents a novel deep intra-image contrastive learning using a Siamese network.

Self-similarity Driven Scale-invariant Learning for Weakly Supervised Person Search

A novel one-step framework based on self-similarity driven Scale-invariant Learning (SSL) to enhance the discriminative power of the features in an unsupervised manner and introduces a dynamic multi-label prediction which progressively seeks true labels for training.

MEVID: Multi-view Extended Videos with Identities for Video Person Re-Identification

A semi-automatic annotation framework and GUI that combines state-of-the-art real-time models for object detection, pose estimation, person ReID, and multi-object tracking is developed and evaluated.

An Efficient Person Search Method Using Spatio-Temporal Features for Surveillance Videos

An efficient person search method that employs spatio-temporal features in surveillance videos that considers the spatial features of persons in each frame, but also utilizes the temporal relationship of the same person between adjacent frames.

Efficient Image Super-Resolution with Feature Interaction Weighted Hybrid Network

Extensive quantitative and qualitative experiments show that the proposed FIWHN can achieve a good balance between performance and efficiency, and is more conducive to downstream tasks to solve problems in low-pixel scenarios.

Cross-receptive Focused Inference Network for Lightweight Image Super-Resolution

A lightweight Cross-receptive Focused Inference Network (CFIN), a hybrid network composed of a Convolutional Neural Network (CNN) and a Transformer, which can achieve a good balance between computational cost and model performance.

Transformer in Transformer as Backbone for Deep Reinforcement Learning

The Transformer in Transformer (TIT) backbone is proposed, which cascades two Transformers in a very natural way: the inner one is used to process a single observation, while the outer one is responsible for processing the observation history; combining both is expected to extract spatial-temporal representations for good decision-making.
