20.500.12556/DKUM-15640 RAZPOZNAVANJE OBRAZOV IN OČI V DIGITALNIH SLIKAH FACE AND EYE RECOGNITION IN DIGITAL IMAGES V tem diplomskem delu se ukvarjamo z razpoznavanjem obrazov in oči na digitalnih slikah. Najprej pregledamo obstoječe metode s tega področja, zatem pa razvijemo in implementiramo lasten algoritem za omenjen problem. Pri načrtovanju algoritma smo privzeli, da mora biti vhodna slika dobro osvetljena, na sliki se lahko nahaja zgolj ena oseba, pogled osebe pa je lahko poljuben. Algoritem sestoji iz treh zaporednih korakov. V prvem koraku ločimo obraz od ozadja, nato pa obraz izrežemo iz vhodne slike. V tretjem koraku še v zgornji polovici izrezane slike poiščemo oči. Uporabljena segmentacijska in klasifikacijska metoda je pragovna operacija. Algoritem smo preizkusili na 70 testnih slikah velikosti 255 x 300 slikovnih elementov, ki smo jih zajeli z digitalnim fotoaparatom. Uspešnost razpoznavanja oči je bila 85 % pri poljubnem pogledu osebe, pri frontalnem pogledu osebe pa je ta uspešnost narastla na 92,4 %. In this thesis we deal with recognition of faces and eyes in digital images. Firstly, existing methods from this research area are reviewed, afterwards we develop and implement our own algorithm for the mentioned problem. We presume by designing this algorithm that the input image is well illuminated; that only one person may appear in the image; whereas person’s look can be arbitrary oriented. This algorithm consists of three sequential steps. In the first step, we separate the face from the background, followed by cropping the face out of the input image. In the third step, we search for eyes in the upper part of the face image. The used segmentation and classification method is thresholding. The algorithm was tested on 70 testing images with dimension of 255 x 300 pixels, which were captured by using a digital camera. Eye recognition efficiency was 85 % at arbitrary person’s look, at frontal person’s look this efficiency rose to 92.4 %. digitalna obdelava slik razpoznavanje obrazov razpoznavanje oči segmentacija digital image processing face recognition eye recognition segmentation true true false [U.
