Abstract:V diplomskem delu raziskujemo možnosti uporabe paralelizacije pri zaznavanju obrazov s pomočjo knjižnice OpenCV. V uvodu predstavimo digitalno zaznavo obrazov z metodo iz OpenCV ter možnosti, ki se ponujajo za njeno pohitritev. Naš cilj je natančno preučiti obstoječo metodo ter jo pohitriti z različnimi postopki. Najprej se lotimo analize možnih pristopov pohitritve te metode, študiramo pa tudi njihove omejitve v praksi. Osrednji del diplome je posvečen razvoju in analizi lastne rešitve, ki temelji na pohitritvi osnovne metode za razpoznavanje obrazov iz OpenCV. Razvili smo jo kot množico različnih pristopov pohitritve. Ugotavljamo, da so implementirani postopki precej hitrejši od obstoječe rešitve iz OpenCV, ter da so nekateri bolj primerni za statične slike, nekateri pa za realno-časovno zaznavo. Z našim pristopom smo dosegli pohitritev do devet krat, glede na osnovno metodo zaznavanja obraza.

Title:RAPID FACE RECOGNITION BY USING OPENCV LIBRARY
Abstract:The thesis investigates the use of parallelization in face detection using OpenCV library. In the introduction, we present a method for face detection in OpenCV and the opportunities offered to improve its performance. Our goal is to carefully examine the existing method, and speed up by different procedures. First, we start the analysis of possible approaches to performance improvements of this method as well as their limitations in practice. The main part of the diploma is dedicated to developing and analyzing our own solution, based on the performance improvements of the basic methods for face detection from OpenCV. It was developed as a multitude of different approaches for performance improvements. We find that procedures that are implemented are much faster than existing solutions in OpenCV, and that some are more suitable for static images, but some for real-time detection. With our approach we have achieved a speed up of nine times, compared to the basic face detection method.
Keywords:face detection, computer vision, parallelization, digital images
