Abstract：Iris recognition technology,as the simplest and most accurate human biometric technology,has attracted more and more attention.At present,the CS-LBP operator has achieved a good recognition result in the field of iris recognition because of its high efficiency and gray-scale invariance.But it didn’t con-sider the influence of the center pixel on the iris texture. Therefore,this paper proposes an effective im-proved method based on D-LBP for iris recognition. It compares the neighboring pixels with the center pixels,and redefines the calculation method of the signature description codes. This method not only re-duces the dimension,but also solves the problem of the loss of the center pixel of CS-LBP algorithm.And the experiments show that the method proposed by the paper has a better recognition effect compared with LBP and CS-LBP methods.
