Abstract

A kind of ATM machine input device that the present invention carries out identification by iris, comprises ATM machine input device and the iris recognizer that is connected with the electric signal of ATM machine input device, and described iris recognizer comprises: (1) sampling module; (2) preset Processing module; (3) feature coding module, for extracting and coding the feature of iris image, it comprises LBP operator processing submodule for the first time, LBP operator processing submodule for the second time, LBP operator for the 3rd time Processing sub-module and the fourth LBP operator processing sub-module; (4) code matching module. The invention increases the correlation between the central point and other surrounding neighborhoods, and can satisfy image textures of different scales and frequencies. After multiple LBP operator processing sub-modules, the correlation between the central point and surrounding neighborhoods is not affected , continuously reduce the encoding length, save storage space, reduce the amount of calculation, improve the recognition speed, enhance the recognition accuracy, and obtain higher robustness.

Description

technical field [0001] The invention relates to the design field of ATM machine input devices, in particular to an ATM machine input device for identifying through iris. Background technique [0002] In the related art, the ATM machine input device that recognizes through the iris usually adopts the basic LBP (Local Binary Pattern) operator to extract and encode the iris image features, and the LBP operator is a method for describing the texture features in the gray scale range of the image , has strong robustness to illumination changes, so it is widely used in image texture feature extraction. [0003] The basic LBP operator is generally defined as: in a 3×3 window by the center point n c and its surrounding 8 neighbors n 0 ,... n 7 composition, where the texture T is defined as: T=(n 0- no c ,n 1- no c ,...,n 7- no c ), binarize it, and use n c As the threshold, the 8 points of the neighborhood and n c Comparison, if the value greater than the center point is m...
