PAR @WACV'24 2024 : WACV’24 Pedestrian Attribute Recognition and Attributed-based Person Retrieval Challenge


When Sep 13, 2023 - Oct 27, 2023
Where N/A
Submission Deadline TBD

Call For Papers

We cordially invite you to participate in our WACV’24 Pedestrian Attribute Recognition and Attributed-based Person Retrieval Challenge

Challenge description: The challenge will use an extension of the UPAR Dataset, which consists of images of pedestrians annotated for 40 binary attributes. For deployment and long-term use of machine-learning algorithms in a surveillance context, the algorithms must be robust to domain gaps that occur when the environment changes. This challenge aims to spotlight the problem of domain gaps in a real-world surveillance context and highlight the challenges and limitations of existing methods to provide a direction for future research. It will be divided in two competition tracks:
Track 1: Pedestrian Attribute Recognition: The task is to train an attribute classifier that accurately predicts persons’ semantic attributes, such as age or clothing information, under domain shifts.
Track 2: Attribute-based Person Retrieval: Attribute-based person retrieval aims to find persons in a huge database of images called gallery that match a specific attribute description. The goal of this track is to develop an approach that takes binary attribute queries and gallery images as input and ranks the images according to their similarity to the query.
