基于均匀量化的二维多尺度排列熵算法
Two-dimensional multi-scale permutation entropy algorithm based on uniform quantization
摘要
Abstract
In order to solve the problem that equal values in the subsequence lead to an increase in the probability of cer-tain ordinal patterns when extending the permutation entropy algorithm to two-dimensional domain,a two-dimensional multi-scale permutation entropy based on uniform quantization(MUPE2D)algorithm based on uniform quantization was proposed.By redefining the ordinal patterns based on uniform quantization,the effect of equal values on the calculation was eliminated.The MUPE2D algorithm was used to investigate various synthetic textures,MIX2D(p)images and en-crypted images.The results reveal that MUPE2D is able to effectively quantify the complexity and information conceal-ment capabilities of encrypted images even if there are a large number of equal values.Consequently,the MUPE2D algo-rithm provides an effective means for evaluating images.关键词
