A New Method of Sea-Sky-Line Detection

Aim at the problem of sea-sky-line detection in sea-sky background image, a new method which is based on histogram analysis and linear fitting is proposed. It can obtain the information of pixels near the Sea-sky-line through an analysis of the histogram, and calculating the rough area to get rid of irrelevant pixels in order to extract the sea-sky-line through the method of linear fitting. The experimental results show that this method can detect out sea-sky-line under complicated sea-sky background effectively, and has many advantages such as strong robustness, speedy calculation and high practical value.
