Processing and Enhancement of Palm Vein Image in Vein Pattern Recognition System

Now a day’s biometric is playing a key role in several fields. A captured image from any kind of sensing element must be processed before the extraction of features. This paper discusses about image processing approach for vein pattern. Hand vein patterns are among the biometric traits being investigated today for identification purposes, attracting interest from both the research community and industry. As an important member of biometric family, the vein patterns rely on the interior biological information of the body, and therefore, cannot be easily damaged, changed or falsified. This paper includes filtering techniques, contrast enhancement strategies and segmentation processes. During this work, five different image filtering methods are used to remove noise from the image. This paper presents image enhancement operations and there result when applied on multispectral vein image. The noise removal and enhancement operations are much helpful to extract the vein pattern and features.
