Infrared Small Weak Target Detection via HOSA
2009 Fifth International Conference on Information Assurance and Security, 2009After the characteristics and shortage of some old algorithm about the infrared small weak targets detection being analyzed, a kind of new detection algorithm via high order spectral analysis is proposed for single frame image. Taking the gray level data of the image ground as the noise signal, the gray level data of small weak targets as the harmonic ...

Facet-based Detection for Small Infrared Targets
2006 8th international Conference on Signal Processing, 2006A fusion detection method for small weak infrared target based on bivariate cubic facet fitting (BCFF) is proposed. Experimental results on real infrared image sequences in background of sea and sky demonstrate that our present method has high probability of detection (P d) and low false alarms (Pf)

Principal curvature for infrared small target detection
Infrared Physics & Technology, 2015Abstract Small target detection in infrared image with complex background and low signal–noise ratio is an important and difficult task in the infrared target tracking system. In this paper, a principal curvature-based method is proposed. The principal curvatures of target pixels are negative and their absolute values are larger than that of ...

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

An Efficient Algorithm for Infrared Small Target Detection
2009 Second International Conference on Information and Computing Science, 2009An improved efficient fractal algorithm, based on higher-order statistics (HOS), is presented for infrared (IR) small target detection under complex background of a single image. This algorithm is divided into two parts: coarse location and fine location.
