| Summary: | Image degradation is a significant issue in medical imaging, as it may obscure the fine details of anatomical structures and organizations. This not only reduces the usability of the images thus increasing the time and monetary costs associated with diagnostic procedures, but also significantly impact the accuracy of subsequent image analysis and interpretation. Noise and blur are are the two most common types of degradation. This project evaluates and compares the effectiveness of several image filtering methods, including Gaussian filter, Median filter, DWT filter, NLM filter, BM3D method, U-Net and Restormer model in restoring medical images with various levels and types of synthetic noise or blur to highlight the performance of deep learning based methods like U-Net and their great potential for application in medical image processing.
