Fighting Crime with Genetic Algorithms

An article at NewScientist.com discusses the application of genetic algorithms to improve a certain crime fighting tool: creating a suspect's likeness from the memory of a witness.
Typically when a person witnesses a crime and can see the perpetrator, detectives will aid the witness in creating a picture of the suspect. This is sometimes done with the help of an artist who draws the picture or with software incorporating a huge database of facial features that the witness can swap out. These processes usually take several hours and sometimes are not very accurate.
A new software package uses evolutionary algorithms to streamline this process. The software starts by gathering a few general features such as race, gender, and hairstyle. After this, the software creates nine mutations of the composite and shows them to the witness. The witness picks the best one and the process repeats.
Using this evolutionary process takes much less time and generally results in a much more accurate picture. |
