Ship Type Classification by Shape and Upper-structures on High-resolution satellite images

In these days, Microwave radars are used for observing maritime traffic. On the other hand, we have not enough infrastructures to watch the traffic especially at the coastal sea and the Ocean area. Therefore we try to make new method of finding vessels in the maritime area. We have already suggested a technique of classification by their colors in our last report. Vessels have not only deck colors but also their own shapes and upper structures. We focus on them to classify their ship type in this report. As the first step, we make new visual processing tool for analyzing the vessel's upper structures and their shapes. Our tool can show the elements of the shape using Hough Transform. In this paper, we show characteristics of the Hough Transform results using this tool.
