PoWer: Polar Wavelet-Gaussian Filter for ring artifact suppression in CT Imaging Systems
In X-ray Computerized Tomography (CT), ring artifacts are caused by imperfect detector elements as well as by defects or impurities on the scintillator crystals. They appear on CT images as a number of dark concentric rings superimposed on the structures being scanned. Posts processing such as noise reduction, binarization, or segmentation of image information are significantly complicated by t...
متن کاملHybrid color filter array demosaicking for effective artifact suppression
Color filter array (CFA) demosaicking is an essential process for restoring full-color images from incomplete color samples acquired by single-sensor digital cameras. We present two main contributions to CFA demosaicking. First, we analyze the causes of two main types of CFA demosaicking artifacts and examine the schemes that are effective in suppressing them, respectively. Second, by combining...
متن کاملComplex artifact suppression using vestigial sideband filter in Fourier-domain optical coherence tomography.
In order to achieve computationally efficient mirror image rejection during the off-pivot, full-range approach in spectral-domain optical coherence tomography, we used a vestigial sideband (VSB) filter in place of a Hilbert transform. The appropriate choice of the VSB filter parameters enabled almost complete removal of one sideband with much reduced computational load. To determine the optimal...
متن کاملRinging Artifact Suppression Using Sparse Representation
The article refers to the problem of ringing artifact suppression. The ringing effect is caused by high-frequency information corruption or loss, it appears as waves or oscillations near strong edges. We propose a novel method for ringing artifact suppression after Fourier cut-off filtering. It can be also used for image deringing in the case of image resampling and other applications where the...
متن کاملLow-cost Automatic Inpainting for Artifact Suppression in Facial Images
Facial images are often used in applications that need to recognize or identify persons. Many existing facial recognition tools have limitations with respect to facial image quality attributes such as resolution, face position, and artifacts present in the image. In this paper we describe a new low-cost framework for preprocessing low-quality facial images in order to render them suitable for a...
