This paper presents a new method for unsharp masking for contrast enhancement of
images. The approach employs an adaptive filter that controls the contribution of the …

The cubic unsharp masking method is introduced in this paper. It is demonstrated, through
both a statistical study and some computer simulations, that the proposed method has a …

The extraction of tectonic lineaments from digital satellite data is a fundamental application
in remote sensing. The location of tectonic lineaments such as faults and dykes are of …

Stereo cameras are now commonly used in more and more devices. Nevertheless, visually
unpleasant images captured under low-light conditions hinder their practical application. As …

Abstract Non-Linear Polynomial Filters (NPF) consists of a schema of linear and quadratic
filter components operating as a fusion of low-and high pass filters. NPF has shown …

The linear unsharp masking technique used in image contrast enhancement is modified in
this article by introducing a control term expressed as a rational function of the local input …

传统的医学图像增强算法存在对噪声敏感且易陷入欠增强或过增强等不足,
本文首先利用量子信号处理基本原理. 定义了两种不同的像素量子比特表达形式; 然后 …

In this paper, we propose a novel hybrid network with Laplacian enhancing unit for image
enhancement. We combine the merits of two representative enhancement methods, ie, the …

A new scheme of unsharp masking for image contrast enhancement is presented. An
adaptive algorithm is introduced so that a sharpening action is performed only in locations …

It is still a challenge to improve the efficiency and effectiveness of image denoising and
enhancement methods. There exists denoising and enhancement methods that are able to …
