Claim One:
1. An apparatus for extracting feature information, the apparatus comprising: a first interface generating plural tile images from a first source image by reading respective divided portions from the first source image stored in a high-capacity short-term memory; and a feature information extractor extracting feature information from at least one of the plural tile images by applying a feature transform to the at least one tile image, wherein the first interface generates the at least one tile image by dividing the first source image, into at least one of the respective portions of the first source image, based on a horizontal resolution of the first source image, and wherein the first interface completes a writing of the generated at least one tile image to a buffer memory having less capacity than the high-capacity short-term memory, even when a horizontal resolution of the first source image results in a quantity of data that is greater than a horizontal capacity of the buffer memory.
