Abstract

Multi-modality medical images are essential in healthcare as they provide valuable insights for disease diagnosis and treatment. To harness the complementary data provided by various modalities, these images are amalgamated to create a single, more informative image. This fusion process enhances the overall quality and comprehensiveness of the medical imagery, aiding healthcare professionals in making accurate diagnoses and informed treatment decisions. In this study, we propose a new hybrid pre-processing approach, Laplacian Filter + Discrete Fourier Transform (LF+DFT), to enhance medical images before fusion. The LF+DFT approach highlights key details, captures small information, and sharpens edge details, effectively identifying meaningful discontinuities and modifying image frequencies from low to high. The sharpened images are then fused using the Stationary Wavelet Transform (SWT), an advanced technique. Our primary objective is to improve image clarity and facilitate better analysis, diagnosis, and decision-making in healthcare. We evaluate the performance of the resultant images both visually and statistically, comparing the novel SWT (LF+DFT) approach with baseline techniques. The proposed approach demonstrates superior results on both breast and brain datasets, with evaluation metrics such as Root Mean Square Error (RSME), Percentage Fit Error (PFE), Mean Absolute Error (MAE), Entropy, and Signal-to-Noise Ratio (SNR) confirming its effectiveness. The technique aims to enhance image quality, enable better medical analysis, and outperform existing fusion methods. In conclusion, our proposed LF+DFT approach followed by SWT fusion shows promising results for enhancing multi-modality medical images, which could significantly impact medical diagnosis and treatment in the future.
