Introduction
Important applications related to PRIP Lab research include face recognition, fingerprint identification, document image analysis, 3D object recognition,
robot navigation, and visualization/exploration of 3D data.
PRIP Lab faculty and students investigate the use of machines to recognize a variety of patterns or objects. Methods are developed to sense objects,
to discover which of their features distinguish them from others, and to design algorithms that can be used by a machine to classify or cluster objects.
Since many applications use a sensed image to initially represent the object much PRIP Lab research deals with images. A significant portion of our research
focuses on the development of algorithms to do feature extraction (such as finding the ends of ridges in a fingerprint) and matching (such as matching ridge
endpoints across two fingerprints) and on the organization of data to support efficient matching
Some recent projects include biometric authentication, automatic surveillance and tracking of people in a work area, face modeling, digital watermarking,
medical image segmentation, and analyzing structure of online documents. Description of both current and recent research projects can be found under
research from www.cse.msu.edu
Face Recognition Videos
3d Face
A 3D model of a face can be acquired using a laser scanner. We use this data to generate 2D images of the face under various
poses and lighting conditions to improve recognition. It is also used for 3D matching.
Face Expression
Using the 3D data of the face, expressions can be learned and applied to neutral models in order to better match faces with varying expression.
3D Finger
The latest technology for capturing fingerprints is able to acquire the finger in 3D. Typically, when fingerprints are captured, they become
distorted when the finger is pressed against a surface, where other problems with smearing and residue can occur. 3D fingers can be matched with 2D pressed images or with other
3D fingers without such problems.
Fingerprint Alignment
Automatic fingerprint matching is performed by applying image processing algorithms, extracting minutiae, finding the correspondences between a stored
finger and the input finger, and finally computing a score based on how well the minutiae match.
