Efficient Speckle Noise Filtering of SAR Images [PDF]
Journal of Astronomy and Space Sciences, 1998 Any classification process using SAR images presupposes the reduction of multiplicative speckle noise, since the variations caused by speckle make it extremely difficult to distinguish between neighboring classes within the feature space.

Intrinsic speckle noise in in-line particle holography due to poly-disperse and continuous particle sizes [PDF]
, 2000 In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...

Signal diversity for the reduction of signal dropouts and speckle noise in a laser-Doppler extensometer [PDF]
, 2022 A recently demonstrated laser-Doppler extensometer is affected by signal dropouts caused by speckle noise, whereby the carrier-to-noise ratio (C/N) falls below the so-called frequency-modulation threshold.

Reduction of Multiplicative Noise in Radar Images
Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. A radar image is an image obtained by remote sensing the earth's surface with a radar device. Radar images are characterized by background graininess caused by speckle noise, which should be filtered to improve the quality of radar images ...

Non-Local SAR Image Despeckling Based on Sparse Representation
Remote Sensing, 2023 Speckle noise is an inherent problem of synthetic aperture radar (SAR) images, which not only seriously affects the acquisition of SAR image information, but also greatly reduces the efficiency of image segmentation and feature classification. Therefore,
