Problematika prepoznavanja obrazov s pomočjo fotorobota

diplomsko delo visokošolskega strokovnega študija Varnost in policijsko delo

Povzetek

Diplomska naloga govori o problemih, ki nastajajo pri prepoznavi obrazov s pomočjo fotorobota. Raziskali smo tudi druge teme, ki so v neposredni povezavi s fotorobotom. Najprej smo predelali prepoznavanje: kaj sploh je prepoznavanje, kako poteka, kateri so dejavniki, ki vplivajo na prepoznavanje. V tem sklopu smo opisali še zaznavanje, saj je zelo pomemben del prepoznavanja. Dotaknili smo se napak, ki se pojavijo pri prepoznavanju, in vloge spomina in vida pri prepoznavanju. Opisan je primer, pri katerem je zaradi različnih dejavnikov prišlo do napačne prepoznave in s tem do obsodbe nedolžne osebe. Raziskali smo različne načine prepoznavanja, kot sta na primer prepoznavna vrsta in prepoznava oseb s pomočjo fotografij. Glavna tema je fotorobot. Najprej smo opisali zgodovino fotorobota: kje je nastal in kdo ga je izumil. Raziskali smo različne računalniške programe za izdelavo fotorobotov, ki so danes v uporabi po vsem svetu. Opisali tudi študijo uporabe fotorobota v ZDA: kje vse je v uporabi, kako ga uporabljajo, kako izobražujejo strokovnjake za izdelavo fotorobotov. Ugotavljali smo tudi, kako lahko izboljšamo izdelavo fotorobotov in kako je fotorobot utemeljen v slovenski zakonodaji. Na začetku smo zastavili tri hipoteze, ki smo jih do zaključka diplomske naloge potrdili ali zavrnili. Hipotezi, da mora biti izdelovalec fotorobota umetnik in da je prepoznava s pomočjo fotorobota 100-odstotno učinkovita, smo zavrgli. Hipotezo, da mora biti fotorobot narejen v roku 24 ur oziroma čim hitreje, kot je lahko, pa smo potrdili.

Sekundarni naslov:	ISSUES SURROUNDING FACE RECOGNITION BY FACIAL COMPOSITE
Sekundarni povzetek:	The thesis discusses about problems, which occurs during facial recognition, using a facial composite. Other subjects, regarding the facial composite were researched as well. First, we defined recognition. What is recognition, how is it managed, which are the factors that influence the recognition. In this chapter we also defined perception, which is a crucial factor of facial recognition. Errors, which may occur during facial recognition due to problems with exact vision or memory, were explained. A case, where innocent person was convicted of a crime, due to incorrect facial recognition was presented. The main subject of the thesis is the facial composite. First, the history of facial composite is introduced, where and who invented it. Various different software, which make facial composites, was examined. A case of using a facial composite in the USA was introduced: where is it used, how it is used, how are they educating experts for facial recognition. We have examined how we can improve facial composites and how is the facial composite determined in Slovenian legislation. First, we stated three hypotheses, which one of them was confirmed and two of them discarded during thesis. The hypothesis, saying that the facial composite operator should be an artist was discarded. The hypothesis, saying that the facial recognition using a facial composite has to be 100% efficient was discarded. The hypothesis saying that the facial composite should be made during a 24 hour period was confirmed.
