Integrating wavelet transform and anisotropic diffusion for effective denoising of ultrasound images with superior performance, implemented through multi-scale decomposition and edge-preserving diffusion algorithms
Detailed Documentation
By combining wavelet transform with anisotropic diffusion, we can effectively denoise ultrasound images and enhance image quality. This approach leverages the multi-scale analysis capability of wavelet decomposition and the local characteristic preservation of anisotropic diffusion, enabling superior noise removal while maintaining important image features. The implementation typically involves first applying wavelet decomposition to separate noise components across different frequency bands, followed by anisotropic diffusion that selectively smooths homogeneous regions while preserving edges. This results in clearer images that are easier to observe and analyze. Consequently, this combined methodology demonstrates broad application potential in medical image processing and various other domains where noise reduction and feature preservation are critical.
