Abstract
Opisana je metoda lokalno konveksnih povezanih segmenata, te je ispitana njezina primjena za segmentaciju dubinske slike na objekte. Metoda lokalno konveksnih povezanih segmenata se koristi za segmentaciju slike na osnovu svojstava konveksnosti i konkavnosti objekata. Primjena te metode omogućava dekompoziciju scene na različite objekte što je vrlo važan zadatak robotike. Algoritam se temelji na kreiranju grafa susjedstva supervoksela čiji su čvorovi supervokseli i gdje se promatraju susjedni odnosi između supervoksela koji se mogu promatrati kao konveksne ili konkavne veze. Tada se detektiraju povezani podgrafovi koji predstavljaju segmente povezane konveksnim vezama. Algoritam je izveden koristeći C++ programski jezik u programskom okruženju Microsoft Visual Studio 2013. te PCL biblioteku koja omogućava trodimenzionalnu vizualizaciju slike. Programu su priložene RGB-D slike, a analizom dobivenih rezultata segmentacije moguće je uočiti veliku učinkovitost metode lokalno konveksnih povezanih segmenata u procesu segmentacije slike.
Abstract (english)
A method of locally convex connected patches was described and its application for depth image segmentation is evaluated. The method of locally convex connected patches is used for depth image segmentation based on object convexity or concavity. This method is applicable in robotics and it enables scene decomposition into objects. The considered algorithm creates an adjacency graph of supervoxels, where every patch represents one supervoxel. Edges in the graph are then classified as either convex or concave. Then it detects subgraphs which represent segments. The algorithm is written in C++ programming language and it was implemented in Microsoft Visual Studio 2013. software. PCL library is used for three-dimensional image visualisation. The program was tested using RGB-D images representing the input to the segmentation algorithm. According to the obtained results, the method of locally convex connected patches is shown to be a very effective and reliable
