Small bounding-box filter for small target detection

Optical Engineering, 2021
To detect small infrared targets under the condition of dense clutters, we propose a single-frame target detection algorithm based on a small bounding-box filter, which is characterized by good adaptability to the position and size of a small target. During the small target detection process, the proposed algorithm first searches for the local maximum ...

Small Target Detection Using Optical Flow

2021 IEEE Aerospace Conference (50100), 2021
Detection of small and dim infrared targets plays an important role in many imaging applications. In space imaging, natural phenomena, such as clouds, can confound detection methods. This can be mitigated by using methods which leverage information from multiple spectral bands.

Small target detection using wavelets

Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002
Presents a method for the detection of small objects embedded in a noisy background. The detection is performed on the wavelet transformed image. After a preliminary de-noising pass, the objects are separated from background by exploiting the evaluation of Renyi's information at the different decomposition levels of the wavelet transform.

Detectability of infrared small targets

Infrared Physics & Technology, 2010
Selecting the most appropriate algorithms for detecting small targets in varied infrared image scenes is frequently needed, since the relative characteristics between small targets and backgrounds in varied scenes are disparate. To solve that problem, a novel criterion is proposed in this article to measure the difficulty in distinguishing small ...
