Abstract

Tema ovog rada je izvedba elastičnog sustava za lokalizaciju objekata na slici. Uvelike inspiriran već postojećim radom i implementacijom koja koristi DPM pristup, rad proučava modeliranje objekta pomoću više manjih dijelova. Detaljno se opisuje treniranje jednog takvog modela, kao i ispitni skup Pascal VOC koji je korišten za treniranje modela i testiranje performansi modela. Obrađen je rad koji koristi dubinske informacije za detekciju kao moguća inspiracija za dodatno poboljšanje sustava. Izneseni su dobiveni rezultati te prokomentirani u usporedbi sa rezultatima postojeće implementacije. Sustav je izveden u programskom jeziku c++.

Abstract (english)

The aim of this paper is implementation of an elastic system for object localization in a picture. Greatly inspired by an existent implementation which uses DPM, this paper explores object modeling by using smaller parts and not as an undivisible whole. Model training is explained in detail, along with Pascal VOC dataset, used for training and testing the model. A paper which uses depth information is used as an example of possible upgrade to the developed system. Achieved results are presented and compared with those of the original implementation. The system is written in c++ programming language.
