Special Issue Information

Dear Colleagues,

Biomedical image processing is an interdisciplinary field that spans several disciplines, including electrical engineering, computer science, physics, mathematics, physiology, and medicine. Various imaging techniques have been developed, providing many approaches to study the body, including X-rays for computed tomography, magnetic resonance imaging, ultrasound, positron emission tomography, elastography, single-photon emission computed tomography, functional near-infrared spectroscopy, endoscopy, thermography, and photoacoustic imaging. Bioelectric sensors, when used in high-density systems (for example, in electroencephalography or electromyography), can also provide maps that can be studied using image processing methods. Biomedical image processing has an increasing number of important applications, for example, in studying the internal structure or function of an organ and in diagnosing or treating disease. When combined with classification methods, it can support the development of computer-aided diagnostic (CAD) systems, for example, for the identification of diseased tissue or a specific lesion or malformation. Recent developments in deep learning approaches have also allowed information to be directly extracted (e.g., via segmentation or classification) from medical images.

The aim of this Special Issue is to collect high-quality contributions that document a wide range of image processing applications to solve biomedical problems. The topics of interest include (but are not limited to) image enhancement, registration, segmentation, restoration, compression, and movement tracking, with the aim of identifying the tissue properties or pathology of a patient.

Few-shot classification algorithms have gradually emerged in recent years, and many breakthroughs have been made in the research of migration networks, metric spaces, and data enhancement. However, the few-shot classification algorithm based on Graph Neural Network is still being explored. In this paper, an edge-weight single-step memory-constraint network is proposed based on mining hidden features and optimizing the attention mechanism. According to the hidden distribution characteristics of edge-weight data, a new graph structure is designed, where node features are fused and updated to realize feature enrichment and full utilization of limited sample data. In addition, based on the convolution block attention mechanism, different integration methods of channel attention and spatial attention are proposed to help the model extract more meaningful features from samples through feature attention. The ablation experiments and comparative analysis of each training mode are carried out on standard datasets. The experimental results obtained prove the rationality and innovation of the proposed method. Full article
