Abstract
It is very important to reduce the number of cells in raster data such as 2D image and so forth. In this paper, we deal with the "octgrid" model which is an octal degree grid graph model. The "octgrid" model is suitable for raster data with heterogeneous parts and can be used to reduce the number of cells in raster data. In this paper, we investigate change ratio of the number of cells when some regions are rotated in 2D images. In addition we describe that the change ratios by the "octgrid" model are less than ones by the quadtree.
