1. An image processing apparatus that analyzes layout of an image, the image processing apparatus comprising:
- an image-feature calculating unit that calculates an image feature amount of image data based on layout of the image;
an image-type identifying unit that identifies an image type of the image data using the image feature amount;
a storage unit that stores therein information on image types each associated with a region extraction method;
a selecting unit that refers to the information in the storage unit to select for layout analysis a region extraction method associated with the image type of the image data; and
a region extracting unit that divides the image data into regions based on the region extraction method.

Abstract
Image data is classified to identify the type of the image data using a feature amount of the image data calculated based on the layout (rough spatial arrangement and distribution of texts and photographs or pictures). Based on the result, a region extraction method that is associated with the type of the image data is selected for layout analysis. According to the region extraction method, the image data is divided into regions.
