CT Image Denoising Using Dual Tree Discrete Wavelet Transform and Wiener Filter
نویسنده
چکیده
Work discussed in this paper is related to the denoising of a CT image before further using it. In order to attain the objective Dual Tree Discrete Wavelet Transform (DT-DWT) and wiener filter are being used to remove the noise that are either introduced in the image during capturing or injected into the image during transmission. The DT-DWT has an excellent performance in the denoising field and Wiener filter can further enhance the image by filtering out the Gaussian noise. In this work PSNR and MSE parameters are being improved using combination of DT-DWT and Wiener filter. Index Terms – Denoising, Dual Tree Discrete Wavelet Transform (DT-DWT), Wavelet Transform (WT), Wiener Filter, Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE).

Image Denoising Using Dual-tree Complex Wavelet Transform and Wiener Filter with Modified Thresholding
This paper presents a new image denoising algorithm based on local variance estimation. In the process of denoising, the Wiener filter is used to remove the noise component of the dual-tree complex wavelet transform (DT-CWT) coefficients. The variances of noise-free coefficients are estimated by the DT-CWT coefficients transformed by modified thresholding. The tests show that the proposed metho...

Wiener filter suppresses noise efficiently. However, it makes the out image blurred. Curvelet preserves the edges of natural images perfectly, but, it produces visual distortion artifacts and fuzzy edges to the restored image, especially in homogeneous regions of images. In this paper, a new image denoising framework based on Curvelet transform and wiener filter is proposed, which can stop nois...
