                         datasets of fluorescent specimens, and has been used to 
                         investigate the structure of biological specimens. However, such 
                         images are affected by the noise introduced during the specimen 
                         preparation and image acquisition processes. Anisotropic diffusion 
                         is a non-linear filter that can significantly improve image 
                         quality while removing noise without blurring edges. This study 
                         investigates the application of anisotropic diffusion in confocal 
                         microscopy images by exploring different models for parameters' 
                         estimation. Our data consists of several slices of extrahepatic 
                         bile ducts containing a network of small vessels named Peribiliary 
                         Vascular Plexus (PVP), which are affected by several sources of 
                         noise. Experimental results show that anisotropic diffusion 
                         improved the volumetric visualization of the PVP. We validated the 
                         results using MSE and PSNR quantitative approaches and qualitative
