Similarity-Driven Edge Bundling: Data-Oriented Clutter Reduction in Graphs Layouts [PDF]
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.

Improving Ship Detection in Clutter-Edge and Multi-Target Scenarios for High-Frequency Radar [PDF]
Remote Sensing, 2021 As one of the main sensors for continuous maritime measurements of sea state parameters, high-frequency surface wave radar (HFSWR) also plays an important role in ship detection and tracking.

False Alarm Analysis of the CATM-CFAR in Presence of Clutter Edge
Radioengineering, 2014 This paper presents a false alarm analysis of the cell-averaging-trimmed-mean constant false alarm rate (CATM-CFAR) detector in the presence of clutter edge. Structure of the CATM-CFAR detector is described briefly.

SymmetryAccurate sea clutter modeling is crucial for clutter suppression in edge radar processing. On resource-constrained edge radar platforms, spatiotemporal statistics, together with device-level computation and memory limits, hinder the learning of representative clutter features. This study presents a transformer-based generative adversarial model for sea

Clutter Edges Detection Algorithms for Structured Clutter Covariance Matrices [PDF]
IEEE Signal Processing Letters, 2022 This letter deals with the problem of clutter edge detection and localization in training data. To this end, the problem is formulated as a binary hypothesis test assuming that the ranks of the clutter covariance matrix are known, and adaptive architectures are designed based on the generalized likelihood ratio test to decide whether the training data ...

An Anti-FOD Method Based on CA-CM-CFAR for MMW Radar in Complex Clutter Background
Sensors, 2020 Traditional constant false alarm rate (CFAR) methods have shown their potential for foreign object debris (FOD) indication. However, the performance of these methods would deteriorate under the complex clutter background in airport scenes.

Edge Bundling Method Based on Homologous Control Points [PDF]
Jisuanji kexue, 2022 Edge bundling is an effective method to reduce the visual clutter caused by the visualization of the node-link diagram with a large number of complex connections.Generally,the edge bundling based on spatial proximity will lead to independent edge ...
