Controlled-source electromagnetic (CSEM) data recorded in industrialized areas are
inevitably contaminated by strong cultural noise. Traditional noise attenuation methods are …

Moiré pattern noise in Scanning Transmission X-ray Microscopy (STXM) imaging introduces
significant errors in qualitative and quantitative image analysis. Due to the complex origin of …

This paper presents an efficient method of quasi-periodic noise detection and filtering.
Taking into account that periodic noise leaves peaks in the amplitude spectrum, the …

Spatial aliasing may affect methods based on grid image processing to retrieve
displacement and strain maps in experimental mechanics. Such methods aim at estimating …

Digital images may be impaired by periodic or quasiperiodic noise, which manifests itself by
spurious long-range repetitive patterns. Most of the time, quasiperiodic noise is well …

Digital x-ray detectors are now the detector of choice in many X-ray examinations. They
have been accepted into clinical practice over the past decade but there are still ongoing …

Acquiring a whole mouse brain at the micrometer scale is a complex, continuous and time‐
consuming process. Because of defects caused by sample preparation and microscopy, the …

Restoration of images corrupted with periodic noise is a fundamental task in digital image
processing since periodic noise affects all imaging processes. The paper presents an …

Periodic noise corrupts digital images during acquisition and transmission stages by adding
repetitive patterns. This study introduces a new adaptive Gaussian notch filter (AGNF) in …

Controlled-source electromagnetic (CSEM) surveys are widely used, but due to the
influence of instrumental or environmental factors, the data obtained from CSEM surveys are …
