Cognitive Approaches to Detection of Small Targets
2020 17th European Radar Conference (EuRAD), 2021This paper shows the early results from an investigation into the potential gain in detection performance achievable by optimizing the parameterization of a CA-CFAR detector to local clutter behaviour. The effect of varying CFAR window length is studied in particular for range correlated time independent samples, and the CFAR Loss (measured by ...

Biologically Inspired Small Target Detection Mechanisms
2007 3rd International Conference on Intelligent Sensors, Sensor Networks and Information, 2007A challenging engineering problem is the ability to detect and discriminate small moving objects against complex moving backgrounds. An evolutionary priority has tuned this capability within fly vision systems, so that they may detect, track and chase other flies, either for territorial or mating purposes.

Small Target Detection Improvement in Hyperspectral Image
2013Target detection is an important issue in the HyperSpectral Image (HSI) processing field. However, current spectral-identification-based target detection algorithms are sensitive to the noise and most denoising algorithms cannot preserve small targets, therefore it is necessary to design a robust detection algorithm that can preserve small targets ...

Small target detection by morphological operations
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015Automatic target detection has an important application field in today's missile technology. Therefore, there are many studies in this field. In this context, morphological operation (MO) based methods were firstly investigated and tested on the prepared scenarios.

Infrared Small Target Detection Using PPCA
International Journal of Infrared and Millimeter Waves, 2008Probabilistic PCA (PPCA) is an extension of PCA which reformulated PCA in a probabilistic framework. In this paper we propose a infrared small target detection algorithm using PPCA analogous to the face detection scheme using PCA, or known as “eigenface”. By computing the parameters of PPCA, we map the input vector from the image onto a subspace. After

Regular and Small Target Detection
2018Although remarkable results have been achieved in the areas of object detection, the detection of small objects is still a challenging task now. The low resolution and noisy representation make small objects difficult to detect, and further recognition will be much harder. Aiming at the small objects that have regular positions, shapes, colors or other

SVD-based scattered small targets detection
2014 International Conference on Multisensor Fusion and Information Integration for Intelligent Systems (MFI), 2014Due to lack of sufficient shape and strength information about the targets present in the entire image obtained in a wide range of scenarios over a long distance, it is very hard to detect these targets using the existing detection methods. In order to solve this problem, this paper proposes a scattered small target detection algorithm based on ...

RISTDnet: Robust Infrared Small Target Detection Network
IEEE Geoscience and Remote Sensing Letters, 2022The infrared (IR) small target detection algorithm with a high detection rate, low false alarm rate, and high real-time performance has significant application value in the field of IR remote sensing. IR small targets in complex backgrounds have low contrast and low signal-to-noise ratio (SNR).

A real-time small target detection network
Signal, Image and Video Processing, 2021Target detection based on deep convolutional neural network has achieved excellent performance. However, small target detection is still one of the challenges in the field of computer vision. In this paper, we present an efficient network for real-time small target detection.

Small target detection by space-borne radiometry
1983 Eighth International Conference on Infrared and Millimeter Waves, 1983The problem of radiometric detection from orbital platforms of small reflective targets against the sea surface is studied. Equations are developed to describe radiometric sensor signal-to-noise ratio in terms of orbital height, RF frequency, antenna diameter and other system parameters.
