Research Abstract |
In order to save the effort of navigation officers with keeping watch quality, it is necessary to select and acquire ship images in radar images automatically. The future purpose of this study is to automatically detect ship images on the radar. Therefore, in this study, we proposed the method for dividing ship images from non-ship images by the image processing and the cluster analysis using radar raster images. As a result of the image processing and the cluster analysis, it was possible to detect a large part of ship images from radar raster images. However, there were many cases that non-ship images were classed as ship images. Therefore, the accuracy rate of cluster analysis results in this study was about 83%.
