Simple Lung Image Segmentation Using Deep Learning

In this document, we explore methods for performing simple lung image segmentation. Lung image segmentation represents a critical task in medical image processing, assisting healthcare professionals in accurately diagnosing and treating pulmonary diseases. By partitioning lung images into distinct regions, we can gain better insights into pulmonary structures and tissues, thereby enabling more precise medical recommendations. Simple lung image segmentation therefore constitutes a key research direction in medical imaging, with researchers continuously developing more efficient and accurate segmentation methodologies.

This document introduces a straightforward deep learning-based approach for lung image segmentation, typically implemented using convolutional neural networks (CNNs). The implementation generally involves preprocessing steps like image normalization and contrast enhancement, followed by a U-Net architecture that utilizes encoder-decoder structure with skip connections for precise boundary detection. Key functions include data augmentation techniques (rotation, flipping) to improve model generalization, and loss functions like Dice coefficient for handling class imbalance. Potential improvements could incorporate attention mechanisms or transformer architectures for enhanced feature extraction, along with post-processing techniques like morphological operations to refine segmentation masks.
