This review article provides a comprehensive survey on state-of-the-art impulse and
Gaussian denoising filters applied to images and summarizes the progress that has been …

At the crossing of the statistical and functional analysis, there exists a relentless quest for an
efficient image denoising algorithm. In terms of greyscale imaging, a plethora of denoising …

In the classical bilateral filter, a fixed Gaussian range kernel is used along with a spatial
kernel for edge-preserving smoothing. We consider a generalization of this filter, the so …

In this paper, a fragile watermarking scheme for color-image authentication and self-
recovery is proposed. Original image is divided into non-overlap** blocks, and for each i …

Reducing noise has always been one of the standard problems of the image analysis and
processing community. Often though, at the same time as reducing the noise in a signal, it is …

Mine operations in the future will require automatic rock characterization at many different
stages, since it can be used to supervise and optimize various processes in the laboratory …

The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to
perform edge-preserving smoothing of images. A direct computation of the bilateral filter …

This paper presents an efficient constant-time bilateral filter that produces a near-optimal
performance tradeoff between approximate accuracy and computational complexity without …

Image watermarking represents a powerful tools for addressing multimedia security and
digital rights issues. In this work, a secure color image watermarking scheme is proposed for …

This paper proposes a single-stage adaptive multi-scale noise filtering algorithm for point
clouds, based on feature information, which aims to mitigate the fact that the current laser …
