ADVANTAGES OF PALMPRINT

• Palm print has relatively stable and unique features

• Collection of data is easy and non-intrusive

• Devices to collect data are economical

• It provides high efficiency using low resolution images

FEATURE EXTRACTION

• Zernike moments are used as features.• Provides good discrimination ability.• The order of Zernike moments determines the

details of information regarding palm print.• Higher the order of moments, greater the details of

the image. • But higher orders are sensitive to noise.

[15] Image Analysis by Moments –Simon Xinmeng Liao

ZERNIKE MOMENTS

• Mapping of an image onto a set of complex Zernike polynomials.

• Orthogonal to each other.

• Represent the properties of an image with no redundancy or overlap of information between the moments.

CONCLUSION

• From this work it is concluded that there is a need of Better biometric system for person authentication with lower resolution capturing device.

• By designing biometric system using palm print we solved the above issue.

• Use of Zernike moments for identification makes it robust to rotational and translational changes.
