Multi-focus image fusion with a natural enhancement via a joint multi-level deeply supervised convolutional neural network

W Zhao, D Wang, H Lu - … on Circuits and Systems for Video …, 2018 - ieeexplore.ieee.org
Common non-focused areas are often present in multi-focus images due to the limitation of
the number of focused images. This factor severely degrades the fusion quality of multi-focus …

Fusion of multi-focus images using differential evolution algorithm

V Aslantas, R Kurban - Expert Systems with Applications, 2010 - Elsevier
In an image captured by a CCD/CMOS sensor with an optical lens, only the objects within
the depth of field are sharply focused. One way to get an everywhere-in-focus image is to …

Cross-modality fusion and progressive integration network for saliency prediction on stereoscopic 3D images

Y Mao, Q Jiang, R Cong, W Gao… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
Traditional 2D image-based saliency prediction models suffer from unsatisfactory
performance when dealing with stereoscopic 3D (S3D) images because eye movements in …

A comparison of criterion functions for fusion of multi-focus noisy images

V Aslantas, R Kurban - Optics Communications, 2009 - Elsevier
In many practical applications, images are distorted by impulsive noise (IN) produced by
image sensors and/or communication channels. This noise may cause miscalculation of …

Large depth-of-field 3D shape measurement using an electrically tunable lens

X Hu, G Wang, Y Zhang, H Yang, S Zhang - Optics express, 2019 - opg.optica.org
The state-of-the-art 3D shape measurement system has rather shallow working volume due
to the limited depth-of-field (DOF) of conventional lens. In this paper, we propose to use the …

Autofocusing method for a digital fringe projection system with dual projectors

M Zhong, X Hu, F Chen, C Xiao, D Peng, S Zhang - Optics express, 2020 - opg.optica.org
This paper presents a novel technique to achieve autofocusing for a three-dimensional (3D)
profilometry system with dual projectors. The proposed system uses a camera that is …

All-in-focus image reconstruction under severe defocus

JR Alonso, A Fernández, GA Ayubi, JA Ferrari - Optics letters, 2015 - opg.optica.org
Limited depth-of-focus is a problem in many fields of optics, eg, microscopy and macro-
photography. We propose a new physically based method with a space variant point spread …

A depth estimation algorithm with a single image

V Aslantas - Optics express, 2007 - opg.optica.org
This paper explains the use of a sharpening filter to calculate the depth of an object from a
blurred image of it. It presents a technique which is independent of edge orientation. The …

Three-dimensional imaging system with both improved lateral resolution and depth of field considering non-uniform system parameters

H Yun, A Llavador, G Saavedra, M Cho - Applied Optics, 2018 - opg.optica.org
In this paper, we propose a new 3D passive image sensing and visualization technique to
improve lateral resolution and depth of field (DoF) of integral imaging simultaneously. There …
