Detectability of infrared small targets
Infrared Physics & Technology, 2010Selecting 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 ...

Improved small target detection for IR point target
2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009In the target detection algorithm based on the bivariate cubic facet fitting (BCFF), the target position can be selected so that the position has the maximum value or energy value of the filtered result. However, in the cluttered environment, it may generate a large number of clutters.

Bio-Inspired Video Enhancement for Small Moving Target Detection
IEEE Transactions on Image Processing, 2021Moving targets at a very large distance from a camera appear small and of low contrast. The low signal-to-noise-ratio and the presence of clutter in the background degrade the detection performance of conventional moving object detection techniques. To address these challenges, we propose temporal pre-processing of video frames using a biologically ...

NMI-Based Small Target Detecting Method
2010 International Conference on Electrical and Control Engineering, 2010For features of synchronous orbit target image, this paper proposes the small target detection method that based on Normalized moment of inertia feature. Firstly, this method uses gray mathematical morphological filter to pre-process the image, improves the target signal noise ratio without affecting the target shape, and then uses constant false alarm

Small-target detection in sea clutter
IEEE Transactions on Geoscience and Remote Sensing, 2004Sea clutter in marine surveillance radar makes the task of detecting small targets a very challenging problem. In this paper, a set of three signal processing techniques designed to suppress unwanted sea clutter radar echo and achieve target detection with no prior knowledge of the ocean and environmental conditions is presented.

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 ...

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.

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

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
