    Superpixel-Aware Transformer with Attention-Guided Boundary Refinement for Salient Object Detection

    Burhan Baraklı1,*, Can Yüzkollar2, Tuğrul Taşçı3, İbrahim Yıldırım2

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.074292 - 29 January 2026

    Abstract Salient object detection (SOD) models struggle to simultaneously preserve global structure, maintain sharp object boundaries, and sustain computational efficiency in complex scenes. In this study, we propose SPSALNet, a task-driven two-stage (macro–micro) architecture that restructures the SOD process around superpixel representations. In the proposed approach, a “split-and-enhance” principle, introduced to our knowledge for the first time in the SOD literature, hierarchically classifies superpixels and then applies targeted refinement only to ambiguous or error-prone regions. At the macro stage, the image is partitioned into content-adaptive superpixel regions, and each superpixel is represented by a high-dimensional region-level… More >

    Mayuri Shukla1, Soraya Boonmag2, Parichart Boontem1, Piyarat Govitrapong1,*

    BIOCELL, Vol.50, No.1, 2026, DOI:10.32604/biocell.2025.072557 - 23 January 2026

    Abstract Ischemic stroke is one of the major causes of long-term disability and mortality worldwide. It results from an interruption in the cerebral blood flow, triggering a cascade of detrimental events like oxidative stress, mitochondrial dysfunction, neuroinflammation, excitotoxicity, and apoptosis, causing neuronal injury and cellular death. Melatonin, a pleiotropic indoleamine produced by the pineal gland, has multifaceted neuroprotective effects on stroke pathophysiology. Interestingly, the serum melatonin levels are associated with peroxidation and antioxidant status, along with mortality score in patients with severe middle cerebral artery infarction. Melatonin exhibits strong antioxidant, anti-inflammatory, and anti-apoptotic properties and preserves More >

    Journal on Artificial Intelligence, Vol.8, pp. 39-49, 2026, DOI:10.32604/jai.2026.076674 - 22 January 2026

    Abstract The rise in convenience packaging has led to generation of enormous waste, making efficient waste sorting crucial for sustainable waste management. To address this, we developed DWaste, a computer vision-powered platform designed for real-time waste sorting on resource-constrained smartphones and edge devices, including offline functionality. We benchmarked various image classification models (EfficientNetV2S/M, ResNet50/101, MobileNet) and object detection (YOLOv8n, YOLOv11n) including our purposed YOLOv8n-CBAM model using our annotated dataset designed for recycling. We found a clear trade-off between accuracy and resource consumption: the best classifier, EfficientNetV2S, achieved high accuracy (96%) but suffered from high latency More >

    Williams Kyei*, Chunyong Yin, Kelvin Amos Nicodemas, Khagendra Darlami

    Journal on Artificial Intelligence, Vol.8, pp. 19-38, 2026, DOI:10.32604/jai.2026.074988 - 20 January 2026

    Abstract The COVID-19 pandemic has underscored the need for rapid and accurate diagnostic tools to differentiate respiratory infections from normal cases using chest X-rays (CXRs). Manual interpretation of CXRs is time-consuming and prone to errors, particularly in distinguishing COVID-19 from viral pneumonia. This research addresses these challenges by proposing a customized EfficientNet-B0 model for ternary classification (COVID-19, Viral Pneumonia, Normal) on the COVID-19 Radiography Database. Employing transfer learning with architectural modifications, including a tailored classification head and regularization techniques, the model achieves superior performance. Evaluated via accuracy, F1-score (macro-averaged), AUROC (macro-averaged), precision (macro-averaged), recall (macro-averaged), inference… More >
