Abstract

Cilj ovog rada bio je usporediti standardne i nove metode za mjeru morfometrijskih obilježja vimena pomoću procesa analize digitalne fotografije. Morfologija vimena analizirana je usporedbom točnosti između izmjera pomične mjerke s onima u ImageJ i R programu. Uspoređivana morfološka obilježja su širina i visina vimena na četrdeset digitalnih fotografija vimena istarske ovce. Nadalje, dobiveni rezultati ukazuju na visoku ponovljivost (r= 0.90 do 0.95) za ImageJ i nešto nižu ponovljivost za R (r= 0.35 do 0.37). Sukladno navedenom, potvrđena je mogućnost korištenja ImageJ digitalne analize fotografije u procjeni obilježja širine i dubine vimena. S druge strane, nove metode analize fotografija u R-Studio pokazale su se manje točnim te vremenski zahtjevnijim za obradu.

Abstract (english)

This study aimed to compare standard and new methods of measuring udder morphometric characteristics using the process of digital photo analysis. The morphology of the udder was analyzed by comparing the accuracy of the slide rule measurements with the measurements in the ImageJ and R software. The morphological features compared are the width and depth of the udder on forty digital photographs of the udder of the Istrian sheep. Furthermore, the results indicate high repeatability (r= 0.90 to 0.95) for ImageJ and somewhat lower repeatability for R (r= 0.35 to 0.37). Following the above, the possibility of using ImageJ digital photo analysis to assess udder width and depth features was confirmed. On the other hand, new photo analysis methods in R-Studio proved less accurate and more time-consuming to process.
