Abstract

U ovom radu predstavljen je postupak automatske obrade slike s ciljem praćenja dinamike određenog procesa te objektivizacije rezultata. Kao prototip problema koriste se slike stanične diobe za vrijeme mitoze. Također, uvodi se pojam centrosoma i predlaže metoda računalnog vida koja određuje njihov položaj na digitalnim slika. Navodimo sve korištene algoritme potrebne za implementaciju metode te ih opisujemo u formalnom smislu. Uz to, predlažu se i dvije metode za računanje kuta otvora vretena na polovima te prikazujemo implementaciju pripadnih algoritama. Konačno, za svaku metodu navodimo završne rezultate.

Abstract (english)

This thesis presents the procedure of automatic image processing with the aim of monitoring the dynamics of a certain process and objectifying the results. Images of cell division during mitosis are used as a prototype of the problem. Also, the term centrosome is introduced and a computer vision method that determines their position on digital images is proposed. The algorithms needed to implement the method are listed and described in a formal manner. In addition, two methods for finding the opening angle of the spindle at the poles are proposed, along with the implementation of the corresponding algorithms. At the end, the final results for each method are shown.
