DMAT: A Dynamic Mask-Aware Transformer for Human De-occlusion

no code implementations7 Feb 2024 Guoqiang Liang, Jiahao Hu, Qingyue Wang, Shizhou Zhang

Human de-occlusion, which aims to infer the appearance of invisible human parts from an occluded image, has great value in many human-related tasks, such as person re-id, and intention inference.

Self-supervised Learning of Event-guided Video Frame Interpolation for Rolling Shutter Frames

no code implementations27 Jun 2023 Yunfan Lu, Guoqiang Liang, Lin Wang

Although events possess high temporal resolution, beneficial for video frame interpolation (VFI), a hurdle in tackling this task is the lack of paired GS frames.

Dual Modality Prompt Tuning for Vision-Language Pre-Trained Model

1 code implementation17 Aug 2022 Yinghui Xing, Qirui Wu, De Cheng, Shizhou Zhang, Guoqiang Liang, Peng Wang, Yanning Zhang

To make the final image feature concentrate more on the target visual concept, a Class-Aware Visual Prompt Tuning (CAVPT) scheme is further proposed in our DPT, where the class-aware visual prompt is generated dynamically by performing the cross attention between text prompts features and image patch token embeddings to encode both the downstream task-related information and visual instance information.

Text-based Person Search in Full Images via Semantic-Driven Proposal Generation

1 code implementation27 Sep 2021 Shizhou Zhang, De Cheng, Wenlong Luo, Yinghui Xing, Duo Long, Hao Li, Kai Niu, Guoqiang Liang, Yanning Zhang

Finding target persons in full scene images with a query of text description has important practical applications in intelligent video surveillance. However, different from the real-world scenarios where the bounding boxes are not available, existing text-based person retrieval methods mainly focus on the cross modal matching between the query text descriptions and the gallery of cropped pedestrian images.
