Biometric verification by palmprint using contourlet transform

Intelligent Decision Technologies, 2016
Palmprint is a reliable biometric that can be used for identity verification because it is stable and unique for every individual. Palmprint images contain rich, unique features for reliable human identification, which makes it a very competitive topic in biometric research.

A New Denoising Method with Contourlet Transform

2006
The contourlet coefficients of natural images are highly correlated across scales especially around boundaries, whereas contourlet coefficients of Gaussan white noise are hardly correlated. Therefore signal coefficients can be sorted out according to the different correlation characteristics between signals and noise.

Contourlet Transform in the Application of the Image Fusion

Applied Mechanics and Materials, 2012
Image Fusion is integrating two or more sensors at the same time or at different times of image or videos equenece to generate a new interpretation of this scene. Its main purpose is increasing reliability or image resolution by redueing uncertainty through redundancy of different images.In this paper, a image fusion method based on contourlet ...
