Infrared Small Target Detection Using PPCA

International Journal of Infrared and Millimeter Waves, 2008
Probabilistic 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

2018
Although 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), 2014
Due 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, 2022
The 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).

Small target detection by space-borne radiometry

1983 Eighth International Conference on Infrared and Millimeter Waves, 1983
The 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.

SAR image enhancement for small target detection

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003
The paper investigates the impact of SAR image enhancement on the performance of small target detection in SAR images. Three SAR image enhancement algorithms are evaluated on large SAR image data-sets. The evaluation results show that image enhancement can greatly improve the performance of false alarm mitigation, and that the level of performance ...
