The significant cause of the ship collision is "Insufficient Lookout". This paper proposes an image processing method for lookout support at sea. The method detects other ships through a navigational image sequence taken by cameras installed at ship's bridge. A frame is segmented into regions. Regions that presumed to be ships are labeled. On the other hand, the optical flow of frame is estimated by Lucas-Kanade method (LKM) that is high-speed version of two-frame differential method. And the pixels that move linearly are selected by inner product. Ships regions are detected by integration with labeled regions and pixels that move linearly. We inspected an effect of proposed method using marine images shot in Tokyo Bay.
