Using six public biometric databases (face, fingerprint, and hand veins), we have shown its efficiency in detecting three kinds of synthetic alterations (blurring, Gaussian noise, and resolution).
The goal of the proposed quality metric is to detect, with a reasonable accuracy, three synthetic alterations which may deeply affect the most widely used matching systems.
In this study, we introduce three types of synthetic alterations as well as three levels for each type using the MATLAB tool: Blurring alteration: blurring images are obtained using a two-dimensional Gaussian filter.
Table 4 shows the efficiency of the proposed metric in predicting the three synthetic alterations (blurring, Gaussian noise, and resize) of data, with a valuable ten-class classification accuracy (going from 82.29% to 97.73% on the training set and from 81.16% to 91.1% on the test set).
The synthetic modification on PEI was performed by emulating the influenza virus hemagglutinin, with an alteration in the charge density of Viromer particles to make their surface charge neutral [ 23].
The role of natural and synthetic antioxidant is alteration of this damage.
Insulin is a lipid-synthetic hormone, thus alteration in a gene regulating insulin gene transcription may alter lipid metabolism as well and contribute to dyslipidemia.
Insulin is a lipid-synthetic hormone, thus alteration in a gene regulating insulin gene transcription may alter lipid metabolism as well and contribute to hypercholesterolemia. Furthermore, overexpression in transgenic mice of the coactivator Bridge-1, homologous of PSMD9, results in elevated triglyceride levels in Bridge-1/PSMD9 with severe diabetes compared to non-transgenic control mice [ 10].
KLF-5 is implicated in alterations in VSMCs during the change to the synthetic phenotype, which includes alterations in gene expression, at the site of vascular injury.
