Special Issue Information

Dear Colleagues,

This Special Issue will advance research on Hybrid Deep Learning and Explainable Artificial Intelligence (XAI) for medical diagnostic imaging, with particular emphasis on symmetry-aware modeling and multiscale computational representations. We welcome contributions that integrate Convolutional Neural Networks (CNNs), Vision Transformers (ViTs), and multiscale, multidimensional, or multiresolution feature extractors to improve classification, segmentation, and anomaly detection tasks. We also encourage studies exploring model-enrichment strategies that incorporate geometric or anatomical symmetries, mirror-aware attention mechanisms, multilevel feature fusion, explainability-driven constraints, or complex network-based descriptors to enhance model performance, robustness, and clinical interpretability. Submissions addressing theoretical formulations, algorithmic innovation, benchmarking frameworks, or real-world clinical deployments will be highly appreciated. Both methodological advances and analytical reviews demonstrating clear scientific novelty, mathematical rigor, and reproducibility are well aligned with the aims of this Special Issue.

Medical image segmentation is challenging due to subtle pathological patterns and the inherent ambiguity of clinical descriptions. Although vision–language models have shown promise, they frequently lack fine-grained perception of structural variability. To address these limitations, we propose the Symmetry- and Variability-Perceiving Conditional Variational Autoencoder (SVP-CVAE). The proposed method integrates a clinical attribute encoder with a morphology-aware enhancement module that incorporates a cross-bilateral symmetry mechanism to explicitly capture symmetry-related variations. By reformulating the segmentation task as a probabilistic prior-to-posterior inference process, SVP-CVAE models the one-to-many mapping between textual attributes and visual realizations. Furthermore, we introduce an attribute-latent contrastive objective to ensure that the latent space encodes discriminative morphological information. Extensive experiments demonstrate that the proposed framework achieves superior segmentation accuracy compared to state-of-the-art methods. Results indicate that SVP-CVAE effectively captures diverse yet anatomically plausible structural variations while maintaining high sensitivity to bilateral symmetry. Comprehensive ablation studies confirm that the performance gains are synergistically driven by the proposed symmetry-perceiving module and the contrastive semantic alignment objective, rather than relying solely on the probabilistic formulation. In conclusion, integrating explicit symmetry perception with probabilistic modeling significantly enhances the reliability and interpretability of multimodal medical image segmentation in complex clinical scenarios.
