Robust approach for palm (Roi) extraction in palmprint recognition system

Palmprint based biometric system is potentially a good choice for biometric applications due to its richness in amount of features. Palmprint contains geometric features, line features, point features, texture features, and statistical features. One of the important stages in the system is pre-processing which contains some operations such as filtering, Morphological operations, Region of Interest (ROI) extraction, normalization, etc. In this paper, we propose a simple methodology for localizing the palm and extracting the ROI. Although pre-processing has been discussed in different papers incidentally, but no definite precise approach has been introduced. We pay more attention towards more essential stage of palm Localization and ROI Extraction.
