Medical Image Denoising with Wiener Filter and High Boost Filtering

The Wiener filter is widely used in image de-noising. It to reduce Gaussian noise. Although the removes noise from image, it causes a loss of edge detail information, resulting blurring image. details are considered high-frequency components. unable reconstruct these In this paper, proposed based on and high-boost for medical images presented. applied degraded First, using Fourier Transformation, high boost converted frequency domain. Secondly, wiener along with filter. Thirdly, deconvolution process achieved Finally, sharper spatial domain, inverse transformation applied. works suppress additive at same time. can keep image's details. Some focus operators used, which contrast, gradient energy, histogram entropy, frequency, order test algorithm. Experimental results showed that gives good compared traditional filters images, especially dark images.
