Definitions
- the present invention relates to a method of identifying an individual from image fragments of at least a portion of the individual and a database containing image characteristics of individuals.
- Fingerprints consist of lines whose shape, interruptions, intersections, directions, among others, are characteristics that make them unique and unique to an individual. These characteristics are identified and coded to be compared with the fingerprint characteristics stored in a database of individuals to, if possible, identify among them the owner of the fingerprints taken. The number of common characteristics makes it possible to evaluate the probability that the fingerprint recorded is the same as the stored fingerprint. Most of the coding and comparison operations are performed by computer-implemented algorithms with a relatively high success rate.
- An object of the invention is to provide an identification method exploiting image fragments.
- a method of identifying an individual from image fragments of at least a part of the individual and a database containing characteristics of images of several individuals including the steps of:
- the grouping of fragments may comprise a number of characteristics sufficient to enable it to be validly compared with the image characteristics of the database.
- the exploitation of these fragments makes it possible to have additional information for the identification of the individual.
- FIGS. 1, 2 and 3 are views of fingerprint fragments;
- FIG. 4 is a view of a group of fragments;
- FIG. 5 is a view of a fingerprint.
- a fingerprint includes lines whose shape, intersections, interruptions, direction ... are characteristics that make it unique and unique to an individual.
- FIGS. 1, 2 and 3 show fragments 1, 2 and 3 of this fingerprint, fragments that could have been found among others at the scene of a crime.
- Each of these fragments has a number of the characteristic points mentioned above.
- These fragments 1, 2, 3 are recovered in the form of digital files either directly from a digital camera or from the scanning of a photograph of the fragment.
- the method according to the invention starts with the step of identifying (or recording) the characteristics of the fragments and coding them in digital form.
- the next step is to determine if several of the fragments 1, 2, 3 correspond to or belong to the same fingerprint. This determination is made from the coded characteristics.
- the correspondence determination is carried out by searching for identical characteristics in fragments. This determination makes it possible to identify overlapping fragments.
- the determination is carried out by searching for coincidences of lines, especially in the vicinity of edges of the fragments.
- This determination makes it possible to identify contiguous fragments by searching for continuity of the lines.
- One approach is to compute a period of lines at one edge of one of the fragments and look for such a period at different locations of the other fragments.
- This determination also makes it possible to identify overlapping fragments.
- the fragments comprising lines
- the determination is based on a shape of the lines by looking for compatibilities between the line forms of the fragments.
- the group 4 then has a number of characteristics greater than that of each fragment 1, 2, 3 taken individually (at best equal to the sum of the numbers of characteristics of each fragment, generally a little less because of the overlaps of fragments). .
- the characteristics of the grouping 4 are then compared to those of fingerprints of identified individuals stored in a database.
- the owner of the fingerprint is assumed to be the one having left the fingerprints on the scene of the crime.
- the invention is not limited to the embodiments that have just been described, but on the contrary covers any variant using, with equivalent means, the essential characteristics stated above.
- the invention is applicable to other types of images than fingerprints, and for example images representing parts of the face.
