    MRSEILA: A modified remote sensing ecological index using local adaptability for enhancing ecological environment quality assessment by Yingzhang Guo, Mingjin Zhan, Hanzeyu Xu, Xiao Li, Junjun Fang, Xingchen Zhou, Dan Lin, Wenhui Chen

    Published 2025-12-01
    “…To enhance the effectiveness of RSEILA in EEQ, we propose a modified RSEILA model (MRSEILA) implemented on the Google Earth Engine (GEE) platform, consisting of three components: (1) optimization of moving window sizes tailored to each target region; (2) automatic recognition and correction of PCA-induced eigenvector direction inconsistencies; and (3) refinement of PCA computation within each circular window to improve the accuracy of EEQ evaluations. …”

    Enhanced electrocardiogram classification using Gramian angular field transformation with multi-lead analysis and segmentation techniques by Gi-Won Yoon, Segyeong Joo

    Published 2025-06-01
    “…This study explores the potential of transforming 1D signals into 2D Gramian Angular Field (GAF) images for improved classification of four ECG categories: Atrial Fibrillation (AFib), Left Ventricular Hypertrophy (LVH), Right Ventricular Hypertrophy (RVH), and Normal ECG. • The study employed GAF transformations to convert 1D ECG signals into 2D representations at three resolutions: 5000 × 5000, 512 × 512, and 256 × 256 pixels. • Segmentation methods were applied to enhance feature localization. • The ConvNext deep learning model, optimized for image classification, was used to evaluate the transformed ECG images, with performance assessed through accuracy, precision, recall, and F1-score metrics.The 512 × 512 resolution achieved the optimal balance between computational efficiency and accuracy. …”
