    This study introduces a Multinetwork Collaborative Feature Learning (MCFL) framework to reduce the need for labeled data in person reidentification (Re-ID). The MCFL framework effectively uses pseudolabels to train models, improving accuracy in matching individuals across different camera views.

    Area of Science:

    • Computer Vision
    • Machine Learning
    • Artificial Intelligence

    Background:

    • Person reidentification (Re-ID) is crucial for matching individuals across disjoint camera views but is challenging due to appearance variations.
    • Current Re-ID methods often require extensive labeled data for training deep neural networks, limiting their practical application.

    Purpose of the Study:

    • To develop a novel framework that alleviates the data annotation requirement for person Re-ID.
    • To enable confident pseudolabel estimation and consistent feature learning for unlabeled sample pairs.

    Main Methods:

    • Introduced a Multinetwork Collaborative Feature Learning (MCFL) framework.
    • Employed a self-paced collaborative regularizer for precise pseudolabel generation by exchanging weight information between networks.
