Research progress on key issues of UWB radar echo information processing for borehole rescue

Meikuang Anquan, 2023
Borehole rescue technology has been widely used as a new rescue technique for the rapid construction of life way. UWB radar can be used to detect life information under non-visual conditions, but the UWB radar echoes are easily affected by the noise ...

Similarity-Driven Edge Bundling: Data-Oriented Clutter Reduction in Graphs Layouts

Algorithms, 2020
Graph visualization has been successfully applied in a wide range of problems and applications. Although different approaches are available to create visual representations, most of them suffer from clutter when faced with many nodes and/or edges.

Compact Polarimetric SAR Ship Detection with m-δ Decomposition Using Visual Attention Model

Remote Sensing, 2016
A few previous studies have illustrated the potentials of compact polarimetric Synthetic Aperture Radar (CP SAR) in ship detection. In this paper, we design a ship detection algorithm of CP SAR from the perspective of computer vision.

Adaptive visual target tracking algorithm based on classified-patch kernel particle filter

EURASIP Journal on Image and Video Processing, 2019
We propose a high-performance visual target tracking (VTT) algorithm based on classified-patch kernel particle filter (CKPF). Novel features of this VTT algorithm include sparse representations of the target template using the label-consistent K-singular

A Clutter Removal Method Based on the F-K Domain for Ground-Penetrating Radar in Complex Scenarios

Remote Sensing
Ground-penetrating radar (GPR) is a classic geophysical exploration method that utilizes the emission and reception of electromagnetic waves to non-destructively detect target objects in the target medium.
