Cartoon+Texture Image Decomposition

open access: yesImage Processing On Line, 2011
In this article we give a thorough description of the algorithm proposed in [A. Buades, T. Le, J.M. Morel and L. Vese, Fast cartoon + texture image filters, IEEE Transactions on Image Processing, 2010] for cartoon+texture decomposition using of a ...

Medical image enhancement using threshold decomposition driven adaptive morphological filter [PDF]

open access: yes, 2008
One of the most common degradations in medical images is their poor contrast quality. This suggests the use of contrast enhancement methods as an attempt to modify the intensity distribution of the image.

Simultaneous inpainting and denoising by directional global three-part decomposition: connecting variational and Fourier domain-based image processing [PDF]

open access: yesRoyal Society Open Science, 2018
We consider the very challenging task of restoring images (i) that have a large number of missing pixels, (ii) whose existing pixels are corrupted by noise, and (iii) that ideally contain both cartoon and texture elements.

Multi-Phase Image Segmentation Based on Low-Rank Prior Decomposition

open access: yesIEEE Access, 2022
Natural images generally contain both structure component and texture component. The existing image segmentation models based on piecewise smooth cannot handle such natural images containing texture well.

Multiresolution-based image fusion with additive wavelet decomposition [PDF]

open access: yes, 1999
The standard data fusion methods may not be satisfactory to merge a high-resolution panchromatic image and a low-resolution multispectral image because they can distort the spectral characteristics of the multispectral data.

DEANet: Decomposition Enhancement and Adjustment Network for Low-Light Image Enhancement

open access: yesTsinghua Science and Technology, 2023
Poor illumination greatly affects the quality of obtained images. In this paper, a novel convolutional neural network named DEANet is proposed on the basis of Retinex for low-light image enhancement.

Exposure Fusion for Dynamic Scenes Combining Retinex Theory and Low-Rank Matrix Completion

open access: yesIEEE Access, 2019
Exposure fusion (EF) directly generates a low dynamic range (LDR) image with similar image quality to the high dynamic range (HDR) image by combining images of different exposures to overcome the limited dynamic range of common digital cameras.

Thermal Image Enhancement using Bi-dimensional Empirical Mode Decomposition in Combination with Relevance Vector Machine for Rotating Machinery Fault Diagnosis [PDF]

open access: yes, 2009
In this study, a novel fault diagnosis system for rotating machinery using thermal imaging is proposed. This system consists of bi-dimensional empirical mode decomposition (BEMD) for image enhancement, a generalized discriminant analysis (GDA) for ...
