Infrared Small Weak Target Detection via HOSA

摘要：

After 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 signal mixed in the noise signal, the gray level data of row and arrange pixel in image are processed via power spectral analysis and high order cumulation analysis to restrain noise and detect harmonic. The distinguishability of detection lies on the piece of the rows being spectrum analyzed on the same time. The advantage of the algorithm consists of adopting the same examine theory, easy accomplishment, having the higher accuracy, and needing data limited by the single frame image only. Finally an example applied the detection algorithm is given.
