船上からの時系列画像を用いた航行船舶の検出実験

抄録

Experiments to extract ships in the spatiotemporal images are performed aiming to provide useful supporting information for ship maneuvering instead of human eyes in the watching. The experimental data is a sequence of images including a moving (traversing) ship. This is obtained by a television camera fixed on an anchoring ship. The optical flow method is applied to the data to extract the vector field of pixel movement. The histograms of horizontal and vertical movement are used so that the background is rejected. The differentiated picture in the time domain is projected to the vertical axis to find the part the ship exists. This data is used to reject the wave part remained. The results for a set of sequential images to extract a ship have been so far satisfactory.
