Robust computer vision system for marbling meat segmentation

Abstract

In this study, we developed a robust automatic computer vision system for marbling meat segmentation. Our approach can segment intramuscular fat from meat samples using images acquired with different quality devices in an illumination varying environment, where there was external ambient light and artificial light; thus, professionals can apply this method without specialized knowledge in terms of image treatment or equipment, as well as without disruption to normal procedures, thereby obtaining a robust solution. The proposed approach for marbling segmentation is based on data clustering and dynamic thresholding. Experiments were performed using two datasets that comprised 82 images of 41 longissimus dorsi muscles acquired by different sampling devices. The experimental results showed that the computer vision system performed well with over 98% accuracy and a low number of false positives, regardless of the acquisition device employed.

Intelligent recognition system of converter station operation text based on computer image acquisition

“…The hardware mode can greatly improve the numerical operation speed and image processing efficiency due to the special processor structure design that supports digital operations. Compared with the software processing mode, the advantages of speed and efficiency are very obvious [5] . Sil, R. et al think that data transmission runs through the whole process of image acquisition and processing, and is one of the key joints of the whole task process.…”

“…CVS has been successfully applied in the analysis of chicken meat (Barbin et al, 2016;Geronimo et al, 2019;Kato et al, 2019), marbling meat (Campos et al, 2020), papaya (Pereira et al, 2018;Udomkun et al, 2017), barley flour (Lopes et al, 2019), pasta (noodle) (Mastelini et al, 2018), and fermented cocoa beans (Oliveira et al, 2021). One of the advantages of CVS is that it allows estimating the general color along with other characteristics on the surface of the sample (Barbin et al, 2016).…”
