In this paper, we describe a new method for the region segmentation of natural scenes in the sea-navigation through a narrow channel, i.e., dividing the natural images into the sky region, the sea region, the land region and the structures used in navigation as remarkable signs. As these structures, the piers of the big bridge over the narrow channel are chosen in this time. The segmentation of this method is executed by the synthesization of the objective figures (the segmented regions) which are cut out from the image separately. For this reason, we allow this method to be robust against the noises which are the figures without the objects on the bilevel images, where the figure consists in "1"-pixels and the background consists in "0"-pixels. Moreover, in this method, we can promote the efficiency of the cutting process for employing HLS-transformation and Sobel filter, and attempt to unify the cutting algorithm as much as possible.
