The ship target detection based on panoramic images

Combing with the characteristics of sea-sky-line in panoramic image and a complicated sea-sky background, a sea-sky-line extraction algorithm for panoramic image and a ship target detection method around sea-sky-line was proposed. Firstly, an improved canny edge detection method based on partition adaptive threshold was used. Then after edge thining, the sea-sky-line edge extraction algorithm was proposed based on the longest curve method and the ellipse fitting was performed to get the sea-sky-line elliptic equation. Finally, the ship target on sea-sky-line detection method was introduced based on the sea-sky-line elliptic equation . The experimental results prove that this method can effectively detect the sea-sky-line under complex sea-sky background.
