Application of Feature Extraction Used in Biometric Identification

We can extract the iris pair to uniquely identify teeth for applications such as person identification, gender identification etc. features is not an easy task due to their variation in scale, rotation, pose, expressio structural component, occlusion, illumination and image condition etc. Hence a huge number of researches are taking place considering these limitations and providing suitable solutions to overcome them. In this paper we have described three applications such as person identification using lip prints, teeth contour and iris pattern based on the concept of feature extraction that are very popular in
