Abstract:

Presently a days noise reduction is a significant job in the medical field. It is useful to conclusion of sickness. The outcome pictures quality is estimated by the PSNR, RMSE and MSE. Speckle noise, gaussian noise, salt and pepper noise are used in the CT, MRI and ultrasound scan. This paper we executed a one of the new filter called WG-filter for restorative picture denoising. The proposed filter is productive and performs will in expelling Gaussian noise and speckle noise and its presentation is poor for salt and pepper noise. Weiner guided filter mainly focuses on speckle noise and gaussian noise removal especially in the CT scan images.
