Lightweight Swin Transformer Based Parameterized Hypercomplex Convolutional Residual U-Net for Lung Nodule Segmentation
摘要
Lung cancer remains one of the leading causes of death worldwide, with lung nodules serving as early indicators of the disease. This study introduces an Efficient Lung Nodule Segmentation Mechanism (ELNSM) to enhance lung cancer detection. This approach consists of three stages: image acquisition, pre-processing, and segmentation. Input images from publicly available datasets are pre-processing using Modified Guided Filtering (MGF) and Upgraded Contrast-Limited Adaptive Histogram Equalization (UCLAHE) to reduce noise and improve contrast. The lightweight Swin Transformer-based Parameterized Hypercomplex Residual U-Net (LightSwin-PHRUNet) is then used to precisely segment lung nodules, with hyper-parameter tuning using the Lyrebird Optimization Algorithm (LBOA). The proposed model is evaluated on the CT-scan, LIDC-IDRI, and LUNG-PET-CT-DX datasets, achieving Jaccard Scores of 0.98, 0.97, and 0.95; Dice Scores of 0.98, 0.98, and 0.97; and Mean IoU values of 0.98, 0.96, and 0.95, respectively. These results demonstrate the robustness and consistency of the proposed segmentation model across varied and challenging medical imaging datasets.
