Abstract
To solve the problem of low accuracy and robustness of sea-sky line detection, this paper presents a method of sea- sky line detection based on the mathematical morphology. Firstly, the mathematical morphology closed-open operation is used to filter and denoise the sea-sky image. Then the Canny operator is used to obtain the sea-sky boundary of the image, Then mathematical morphological operation is used to remove some disturbing points. Finally, the sea-sky line is detected by Hough transform. The experimental results show that the algorithm can accurately and efficiently detect the sea-sky line under the complex sea-sky background.
