Scale-based diffusive image filtering preserving boundary sharpness and fine structures.

Scale-based diffusive image filtering preserving boundary sharpness and fine structures.

Image acquisition techniques often suffer from low signal-to-noise ratio (SNR) and/or contrast-to-noise ratio (CNR). Although many acquisition techniques are available to minimize these, post acquisition filtering is a major off-line image processing technique commonly used to improve the SNR and CN...
