Paper Abstract

By the analysis of the IR imaging characteristics of small marine targets in complex sea background, the small marine targets always appear in the region nearby the sea-sky-line, to improve real-time execution and eliminate the ostensible alarm, the key step of the small sea target detection is to extract and localize the sea-sky-line. Thus, a reliable method of sea-sky-line detection in complex sea background is proposed in this paper. Firstly, medium filter and discrete wavelet transformation (DWT) are adopted to suppress the noise and enhance the contrast; Secondly, the low frequency subimage (cA)and horizontal detail subimage(cH) produced by DWT are combined to extract potential sea-sky-line in the IR image; then the validation technique is adopted to distill the veritable sea-sky-line. The experiment result shows that our method can localize the sea-sky-line precisely, and has strong robustness and higher detection efficiency.
