Abstract
Ovaj diplomski rad usmjeren je na razvoj i verifikaciju automatiziranog postupka računalne analize slike za procjenu kvalitete kruha s dodatkom brašna od žira (Quercus rotundifolia). U istraživanju su analizirani različiti algoritmi segmentacije slike kako bi se odredili ključni parametri strukture kruha, uključujući broj šupljina, prosječnu veličinu šupljina i poroznost. Algoritmi kao što su Default, IsoData, Li, Moments i Otsu pokazali su se najprikladnijima za analizu, pružajući konzistentne rezultate, dok se IsoData algoritam posebno istaknuo kao najuspješniji zbog svoje stabilnosti i pouzdanosti. Nasuprot tome, algoritmi poput MinError, MaxEntropy, Yen i Triangle pokazali su manju učinkovitost zbog varijacija u rezultatima i nerealne filtracije, osobito kod uzoraka s kompleksnom strukturom. Istraživanje je pokazalo da veći udio brašna od žira povećava broj šupljina, prosječnu veličinu šupljina i poroznost kruha, pri čemu uzorci s 100% brašna imaju najvišu vrijednost ovih parametara. Povećanje udjela vode iznad 100% smanjilo je broj šupljina, ali je povećalo prosječnu veličinu šupljina i poroznost kod uzoraka s brašnom od žira. U uzorcima bez žira, udio vode nije imao značajan utjecaj, što ukazuje na ključnu ulogu brašna od žira u formiranju strukture kruha.
Abstract (english)
This thesis deals with the development and verification of an automated image analysis method for the evaluation of the quality of bread with the addition of acorn flour (Quercus rotundifolia). In the study, different image segmentation algorithms were analysed to determine important structural parameters of the bread, including the number of voids, average void size and porosity. Algorithms such as Default, IsoData, Li, Moments and Otsu were found to be the most suitable for the analysis and provided consistent results, with the IsoData algorithm standing out as the most successful due to its stability and reliability. In contrast, algorithms such as MinError, MaxEntropy, Yen and Triangle were less effective due to fluctuations in results and unrealistic filtering, especially for samples with complex structure. The study showed that a higher proportion of acorn flour increased the number of voids, the average void size and the porosity of the bread, with samples containing 100% acorn flour having the highest values for these parameters. Increasing the water content above 100% reduced the number of voids but increased the average void size and porosity in samples with acorn flour. In samples without acorn flour, the water content had no significant effect, emphasising the key role of acorn flour in shaping the bread structure.
