Method of determining an image from an image sequence
First Claim
1. A method of determining a corresponding image for a reference image from an image sequence of a moving object by means of a first and a second motion signal, in which the first and the second motion signal represent the respective variation in time of the states of motion of a first motion and a second motion of the object, the image sequence represents the first motion of the object as a sequence of images of states of motion, the reference image represents a state of motion from the second object motion and is acquired at a reference instant during the second motion of the object, including the following steps:
- a. determining a similarity function by way of a similarity comparison of the first and the second motion signal, b. determining a correspondence instant in the first motion signal by means of the similarity function, the correspondence instant corresponding to the acquisition instant of the reference image from the second motion signal, c. determining, using the first motion signal, that image of the image sequence whose acquisition instant corresponds at least approximately to the correspondence instant.

Abstract
The invention relates to a method of determining a corresponding image of a moving object for a reference image from an image sequence which represents the motion as a sequence of states of motion. To this end, two motion signals, representing the development of the relevant motions, are examined for similarities. Using the similarity function thus obtained, that image in the image sequence can be determined which represents at least approximately the state of motion of the object which is represented in the reference image. Furthermore, the invention relates to a system which is suitable for carrying out the method as well as to a computer program and a computer program product enabling a data processing unit to carry out the method.
