Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue, "Computer Vision, Pattern Recognition, Machine Learning, and Symmetry", on the topic of symmetry/asymmetry. This Special Issue seeks high-quality contributions in the fields of computer vision/pattern recognition/machine learning and symmetry in theory, as well as applications to solve practical application problems.

This Special Issue of Symmetry will collect articles on solving real-world problems by solving data- and learning-centric technologies, including computer vision, pattern recognition, and the correlation between machine learning and symmetry. We are soliciting contributions covering all related topics including, but not limited to, vision, multimedia, biometrics, behavior analysis, adversarial learning, simulation, network security, Internet of Things, and performance. The main criteria for submission are theoretical and application-centric innovative methods aimed at solving real-world problems. There is no limit on the number of pages, but the submissions must demonstrate an understanding of the theme and a contribution to the topic.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Symmetry is an international peer-reviewed open access monthly 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.

Audio-Visual Learning for Multimodal Emotion Recognition
by Siyu Fan, Jianan Jing and Chongwen Wang

Abstract
Most current emotion recognition methods are often limited to a single- or dual-modality approach, neglecting the rich information embedded in other modalities. This limitation hampers the accurate identification of complex or subtle emotional expressions. Additionally, to reduce the computational cost during inference, minimizing [...] Read more.
Most current emotion recognition methods are often limited to a single- or dual-modality approach, neglecting the rich information embedded in other modalities. This limitation hampers the accurate identification of complex or subtle emotional expressions. Additionally, to reduce the computational cost during inference, minimizing the model’s parameter size is essential. To address these challenges, we utilize the concept of symmetry to design a balanced multimodal architecture that integrates facial expressions, speech, and body posture information, aiming to enhance both recognition performance and computational efficiency. By leveraging the E-Branchformer network and using the F1- score as the primary performance evaluation metric, the experiments are mainly conducted on the CREMA-D corpora. The experimental results demonstrate that the proposed model outperforms baseline models on the CREMA-D dataset and an extended dataset incorporating eNTERFACE’05, achieving significant performance improvements while reducing the number of parameters. These findings demonstrate the effectiveness of the proposed approach and provide a new technical solution for the field of emotion recognition. Full article

This paper presents a biologically inspired model, the Stereoscopic Direction Detection Mechanism (SDDM), designed to detect motion direction in three-dimensional space. The model addresses two key challenges: the lack of biological interpretability in current deep learning models and the limited exploration of binocular functionality in existing biologically inspired models. Rooted in the fundamental concept of ’disparity’, the SDDM is structurally divided into components representing the left and right eyes. Each component mimics the layered architecture of the human visual system, from the retinal layer to the primary visual cortex. By replicating the functions of various cells involved in stereoscopic motion direction detection, the SDDM offers enhanced biological plausibility and interpretability. Extensive experiments were conducted to evaluate the model’s detection accuracy for various objects and its robustness against different types of noise. Additionally, to ascertain whether the SDDM matches the performance of established deep learning models in the field of three-dimensional motion direction detection, its performance was benchmarked against EfficientNet and ResNet under identical conditions. The results demonstrate that the SDDM not only exhibits strong performance and robust biological interpretability but also requires significantly lower hardware and time costs compared to advanced deep learning models.
