Abstract
V diplomskem delu bo podrobneje predstavljen video nadzorni sistem, opisane bodo njegove komponente in prikazano, v kakšne namene lahko video posnetek uporabljamo. Opisan je tudi pametni video, njegove aplikacije in način delovanja. Sem spadajo raznovrstne aplikacije za zaznavanje gibanja, aplikacije za izboljšanje kvalitete slik, štetje oz. sledenje ljudem, aplikacije za prepoznavanje registarskih tablic itd. V praktičnem delu sem s pomočjo spletne kamere Philips, omrežne kamere IQEye in digitalnega fotoaparata Canon 1100D posnela osebo, ki se je na različnih razdaljah gibala pred kamerami. Pri snemanju sem uporabljala odprtokodni program iSpy. Najprej je bila oseba 3 m oddaljena od kamere, potem se je razdalja zmanjšala na 2 m in na koncu še na 1 m. Dobljene posnetke in podatke sem analizirala in med seboj primerjala. Zanimalo me je, kako razdalja vpliva na kvaliteto slike določene kamere, kakšno je razmerje med velikostjo osebe na sliki s celotno sliko na različnih razdaljah, kakšna je višina osebe na sliki, velikost obraza, hitrost gibanja osebe in vpliv svetlobe na prepoznavo obraza. Opisana je tudi uporaba javnih IP kamer dostopnih na daljavo. S pomočjo programov iSpy in IP Camera Viewer 3 sem prikazala postopek ogleda, kakšne podatke potrebujemo in kako lahko upravljamo z videom. Na koncu je narejena primerjava obeh programov in funkcij.

Title:Intelligent video surveillance systems and iSpy application
Abstract:
In my thesis I have presented the concept, history, developement and the usages of the modern video surveillance systems. I explain how the recorded video is used within the various types of aplications. There are a lot of inteligent video applications such as video motion detection, camera tampering detection, image enhancement, people and object counting, people tracking, automatic number plate recognition etc. In the second part of the work I used an open source iSpy application to build a practical video surveillance system. I used a Philips web camera, IQEye IP camera and a Canon 1100D digital camera to make video recordings and to compare the image quality. I recorded a person who was walking in front of the camera at three different distances. In the first recording she was around 3m away from the cameras and went from one end to the other in the camera’s view. Than the distance was reduced to 2m and in the end to 1m. I analyzed the recordings and measured various parameters such as the size of the face, the height of the person etc. In the end I described the usage of remote IP cameras. I present the setup process using the iSpy and IP Camera viewer 3 applications, and then I compare their functions.
