Última Computer vision system approach in colour measurements of foods: Part II. validation of methodology with real foods Ciênc. Tecnol. Aliment. TARLAK,Fatih; OZDEMİR,Murat; MELİKOGLU,Mehmet. Abstract The colour of food is one of the most important factors affecting consumers’ purchasing decision. Although there are many colour spaces, the most widely used colour space in the food industry is L*a*b* colour space. Conventionally, the colour of foods is analysed with a colorimeter that measures small and non-representative areas of the food and the measurements usually vary depending on the point where the measurement is taken. This leads to the development of alternative colour analysis techniques. In this work, a simple and alternative method to measure the colour of foods known as “computer vision system” is presented and justified. With the aid of the computer vision system, foods that are homogenous and uniform in colour and shape could be...

Tecnol. Aliment. TARLAK,Fatih; OZDEMIR,Murat; MELIKOGLU,Mehmet. Abstract Agaricus bisporus was washed with 1 g/L sodium chlorite (NaClO2) (SC) solution for 30, 60 and 120 s, packed with a non-perforated polyvinyl chloride (PVC) film and stored at 4 °C for 12 days. Washing the mushrooms with the SC solution and packaging with the PVC film slowed down the change in colour and firmness of the mushrooms, but treating the mushrooms with the SC solution longer than 60 s adversely affected the mushroom texture. After 12 days of storage, the weight loss of the mushrooms packed with the PVC film was less than 10% compared to the control. Headspace O2 concentration decreased while CO2 concentration increased throughout 12 days of storage and reached about 15% and 4%, respectively. Pseudomonas spp. counts for unwashed and...

Ano: 2020 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-20612020005005209 Computer vision system approach in colour measurements of foods: Part I. development of methodology Ciênc. Tecnol. Aliment. TARLAK,Fatih; OZDEMİR,Murat; MELİKOGLU,Mehmet. Abstract The colour assessment ability of the computer vision system is investigated and the data are compared with colour measurements taken by a conventional colorimeter. Linear and quadratic models are built to improve currently used methodology for the conversion of RGB colour units to L * a * b * colour space. For this purpose, two innovative ideas are proposed and tested. First, substantial amount of colour tones is generated to cover as many points in the colour space as possible. Secondly, the colour space is calibrated separately, whereas in previous research in the literature, the colour space is calibrated simultaneously. It is found that the RGB colour units to L * a * b * colour space transformation approach proposed in this study...
