A method for providing information of the orientation of chest and abdomen images on x-ray films. The method optically reads chest image and determines whether the image is a front or side image and the orientation of this image and the handedness of the image. The method also determines where the heart is in a chest front image and the direction the patient is facing in the case of a chest side image. The method optically reads an image and determines whether the image is an abdominal image or not and, if it is, the method determines the orientation of the patient with respect to the image plane.

Method for orienting electronic medical images

A technique for fingerprint classification and/or identification, in which a fingerprint is defined by areas containing patterns of ridges and valleys. At least one local pattern is determined using locations and characterizations of the fingerprint, which are indicated by a rapid change in direction of the ridges and valleys. The fingerprint is classified into types based upon the relative locations and characterizations of said local pattern(s). The fingerprint identification process can utilize minutiae location and angles as well as local pattern characterizations. Neural networks are utilized in determining the local patterns. The amount of data required to store data defining the fingerprints using the local pattern and/or minutiae techniques is significantly reduced.
