Abstract
A method and apparatus for locating elements of a member from digital images taken at different angulations, in which elements present in a first digital image taken at a first angulation are determined. A deformation model of the member between the first angulation and another angulation is determined in order to deduce there from a search region in another digital image taken at the other angulation. Elements present are determined, in a search region of an element marked on the first image which has a high probability of being found. The image of the element is analyzed in order to assess their similarity.

A method for locating elements of interest in a member from a plurality of images taken at different angulations comprising:
- (a) determing elements of interest present in a first image taken at a first angulation;
- (b) determining a deformation model of the member between the first angulation and another angulation different from the first is determined in order to deduce there from a search region in another image taken at the other angulation, in which search region an element of interest marked on the first image has a high probability of being found;
- (c) determing the element so interest present in the other image;
- and
- (d) analyzing the image of the elements of interest in order to assess their similarity.
An imaging system comprising:
- (a) means for emitting radiation (1);
- (b) means for receiving the radiation (3) connected in rotation to the means for emitting radiation;
- (c) means for processing images acquired by the means for receiving;
- wherein the means for processing comprises:
- (d) means for locating elements of interest of a member from a plurality of images taken at different angulations by the means for receiving, the means for locating comprising:

- (2) means for determining a deformation model of the member between the first angulation and another angulation different from the first in order to deduce there from a search region in another image taken at the other angulation, in which search region an element of interest marked on the first image has a high probability of being found;
- (3) means for determining elements of interest present in the search region;
- and
- (4) means for analyzing the image of the elements of interest in order to assess their similarity.
A computer program comprising program code means for implementing a method for locating elements of interest in a member from a plurality of image taken at different angulations, when the program runs on a computer comprising:
- (a) determing elements of interest present in a first image taken at a first angulation;
- (b) determining a deformation model of the member between the first angulation and another angulation different from the first is determined in order to deduce there from a search region in another image taken at the other angulation, in which search region an element of interest marked on the first image has a high probability of being found;
- (c) determing the element so interest present in the other image;
- and
- (d) analyzing the image of the elements of interest in order to assess their similarity.
A storage medium that can be read by a device for reading program code means which are stored therein and which is capable of implementing a method for locating elements of interest in a member from a plurality of image taken at different angulations when the program runs on a computer comprising:
- (a) determing elements of interest present in a first image taken at a first angulation;
- (b) determining a deformation model of the member between the first angulation and another angulation different from the first is determined in order to deduce there from a search region in another image taken at the other angulation, in which search region an element of interest marked on the first image has a high probability of being found;
- (c) determing the element so interest present in the other image;
- and
- (d) analyzing the image of the elements of interest in order to assess their similarity.
