Special Issue Information
Dear Colleagues,
Facial expression recognition (FER) has become a vital research area in computer vision, artificial intelligence (AI), and human–computer interaction due to its wide-ranging applications in fields such as healthcare, security, robotics, and virtual reality. Recent advances in deep learning, neural networks, and multimodal data fusion have significantly improved the accuracy and robustness of FER systems. However, challenges remain in handling variations caused by complex real-world environments, occlusion, privacy concerns, and the need to recognize diverse and subtle emotional expressions across different cultures and contexts. This Special Issue aims to explore the latest developments and emerging trends in FER, addressing both theoretical advancements and practical applications. We seek high-quality original research and review articles that provide novel insights into algorithm development, data augmentation, real-time implementation, and the integration of FER with other AI technologies. This Special Issue will cover a broad range of topics, including multi-modal FER, context-sensitive FER, and privacy-preserving FER systems. By bringing together contributions from leading researchers and practitioners, this Special Issue aims to advance the state of the art in FER and foster the development of more accurate, interpretable, and scalable systems.
This Special Issue offers an opportunity for scientists and professionals from computer science, psychology, and social sciences to exchange concepts, novel solutions, and strategies for advancing the smart analysis of facial expressions. We invite the submission of unpublished, original work that applies advanced techniques and methodologies to all aspects of facial expression recognition covered in this Special Issue.
Suggested Themes:
- Cross-cultural and multi-lingual analysis of facial expressions;
- Real-time FER in healthcare, security, and education;
- Multi-modal emotion recognition;
- Privacy and ethical issues in facial expression data;
- Explainability and interpretability in FER models;
- Recognition of fine-grained and diverse emotional expressions;
- Context-aware and adaptive FER systems;
- Robust facial expression recognition in real environments.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
