Abstract
A lookout is very important in the operation of a ship. Many accidents occur by the insufficiency of a lookout. Many accidents will be able to be prevented previously by automating lookout system. It needs to create the understanding system of an image because a lookout does by vision. This study was done about image segmentation as a first step for that. Because the image of the sea is a natural image, automating lookout system must be adapted to an environment. An image partition system by the system that is adapted and can be changed to simple knowledge and an environment was constructed for that. We try to make it system.
