Sea-sky-line extraction is important to suppress background interference and improve the detection speed of warship target. This paper presents an algorithm based on texture distributing of infrared complicated sea-sky image. A texture model is proposed by analyzing the texture distributing feature at ocean line area of classical sea-sky images. The textural image is got by using gradient operators. Then the positions of likely sea-sky-line can be obtained by clustering the peak value of gradient. The correct sea-sky-line was detected by comparing the textural parameters of all those positions. Experimental results indicated that this algorithm can extract the sea-sky-line under various complicated sea-sky background effectively, and has good adaptation and anti-interference ability.
