Abstract:
1. An information processing apparatus comprising: a Hough transform unit executing Hough transformation on a biometrics image which is image information unique to a living body; and a block detection unit detecting whether a block having a predetermined shape is included in a Hough space image which is a Hough-transformed biometrics image, outputting present position information representing a position at which the block is located in the Hough space image when the block is determined to be included in the Hough space image, the block including a plurality of unit blocks, each having a predetermined size, which are connected with a predetermined inclination, the block detection unit detects the block by using a plurality of types of blocks in which the unit blocks are connected in different manners, in which the different manners include (i) a diagonally right down arrangement, (ii) a diagonally right up arrangement, (iii) a horizontal arrangement, and (iv) a vertical arrangement, and the block detection unit performs detecting processing using the diagonally right down arrangement and the diagonally right up arrangement before using the horizontal arrangement and the vertical arrangement.
