PolSAR Image Classification Using a Superpixel-Based Composite Kernel and Elastic Net

open access: yesRemote Sensing, 2021
The presence of speckles and the absence of discriminative features make it difficult for the pixel-level polarimetric synthetic aperture radar (PolSAR) image classification to achieve more accurate and coherent interpretation results, especially in the ...

Ship Instance Segmentation Based on Rotated Bounding Boxes for SAR Images

open access: yesRemote Sensing, 2023
Ship instance segmentation in synthetic aperture radar (SAR) images is a hard and challenging task, which not only locates ships but also obtains their shapes with pixel-level masks.

Importance of Visual Estimation of Coronary Artery Stenoses and Use of Functional Evaluation for Appropriate Guidance of Coronary Revascularization—Multiple Operator Evaluation

open access: yesDiagnostics, 2021
Background: Visual estimation (VE) of coronary stenoses is the first step during invasive coronary angiography. The aim of this study was to evaluate the accuracy of VE together with invasive functional assessment (IFA) in defining the functional ...

DASANet: A 3D Object Detector with Density-and-Sparsity Feature Aggregation

open access: yesRemote Sensing, 2023
In the field of autonomous driving and robotics, 3D object detection is a difficult, but important task. To improve the accuracy of detection, LiDAR, which collects the 3D point cloud of a scene, is updated constantly. But the density of the collected 3D

In-stent restenosis in acute coronary syndrome—a classic and a machine learning approach

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundIn acute coronary syndrome (ACS), a number of previous studies tried to identify the risk factors that are most likely to influence the rate of in-stent restenosis (ISR), but the contribution of these factors to ISR is not clearly defined. Thus,

U2Fusion: A Unified Unsupervised Image Fusion Network

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2020
This study proposes a novel unified and unsupervised end-to-end image fusion network, termed as U2Fusion, which is capable of solving different fusion problems, including multi-modal, multi-exposure, and multi-focus cases.

MULTIFOCAL IMAGES FUSION [PDF]

open access: yesActa Electrotechnica et Informatica, 2017
The paper deals with the issue of multifocal image fusion. Two techniques of the hierarchical image representation are analyzed herein. The first one is hierarchical decomposition based on the Laplacian pyramid and the second one is based on integer discrete wavelet transformation. After the analysis of the above-mentioned decompositions techniques the

IMAGE FUSION AND IMAGE QUALITY ASSESSMENT OF FUSED IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Abstract. It is of great value to fuse a high-resolution panchromatic image and low-resolution multi-spectral images for object recognition. In the paper, tow frames of remotely sensed imagery, including ZY03 and SPOT05, are selected as the source data.
