The adaptive constant false alarm rate for sonar target detection based on back propagation neural network access

open access: yesIET Signal Processing, 2023
With oceanic reverberation and a large amount of data being the main sources of interference for underwater acoustic target detection, it is difficult to obtain a more robust detection performance by relying on the traditional constant false alarm rate ...

Multi-Scale Strengthened Directional Difference Algorithm Based on the Human Vision System

open access: yesSensors, 2022
The human visual system (HVS) mechanism has been successfully introduced into the field of infrared small target detection. However, most of the current detection algorithms based on the mechanism of the human visual system ignore the continuous ...

Enhancing Target and Rectifying Clutter: A Structure-Guided Frequency Rectification Network for Infrared Small-Target Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Infrared small-target detection (IRSTD) remains challenging under low signal-to-noise ratio conditions, where weak target responses are easily submerged by complex background clutter.

Analysis and Considerations to Lessen Visual Clutter: Multidimensional Associations Between Streetscape Visual Clutter and Urban Perceptions in Shanghai

open access: yesLand
Visual clutter can affect attention, cognitive load, and environmental evaluation, yet streetscape studies often treat visual complexity as a broad construct without distinguishing visual richness from competition among visual features.

A New Edge Patch with Rotation Invariance for Object Detection and Pose Estimation

open access: yesSensors, 2020
Local patch-based methods of object detection and pose estimation are promising. However, to the best of the authors’ knowledge, traditional red-green-blue and depth (RGB-D) patches contain scene interference (foreground occlusion and background ...

Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

open access: yes, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.
