A Flatter Loss for Bias Mitigation in Cross-dataset Facial Age Estimation

no code implementations20 Oct 2020 Ali Akbari, Muhammad Awais, Zhen-Hua Feng, Ammarah Farooq, Josef Kittler

Compared with existing loss functions, the lower gradient of the proposed loss function leads to the convergence of SGD to a better optimum point, and consequently a better generalisation.

AFAT: Adaptive Failure-Aware Tracker for Robust Visual Object Tracking

no code implementations27 May 2020 Tianyang Xu, Zhen-Hua Feng, Xiao-Jun Wu, Josef Kittler

To this end, we propose a failure-aware system, realised by a Quality Prediction Network (QPN), based on convolutional and LSTM modules in the decision stage, enabling online reporting of potential tracking failures.

Dual Encoder-Decoder based Generative Adversarial Networks for Disentangled Facial Representation Learning

no code implementations19 Sep 2019 Cong Hu, Zhen-Hua Feng, Xiao-Jun Wu, Josef Kittler

To be more specific, the encoder-decoder structured generator is used to learn a pose disentangled face representation, and the encoder-decoder structured discriminator is tasked to perform real/fake classification, face reconstruction, determining identity and estimating face pose.

Learning Adaptive Discriminative Correlation Filters via Temporal Consistency Preserving Spatial Feature Selection for Robust Visual Tracking

1 code implementation30 Jul 2018 Tianyang Xu, Zhen-Hua Feng, Xiao-Jun Wu, Josef Kittler

The key innovations of the proposed method include adaptive spatial feature selection and temporal consistent constraints, with which the new tracker enables joint spatial-temporal filter learning in a lower dimensional discriminative manifold.
