This report describes the successful construction of a Colorimeter CK20.1 prototype using TCS3200 sensor based on Arduino Mega-2560 microcontroller for solid foodstuffs inspection. The sample color exposed is presented in RGB form. In this experiment, commercial colorimeter (ColorFlex EZ Spectrophotometer, with output, L*a*b* form) was applied as validator quality performance reading green bean...

The paper presents the recent development and application of image analysis and computer vision system in quality evaluation of products in the field of agricultural and food. It is very much essential to through light on basic concepts and technologies associated with computer vision system, a tool used in image analysis and automated sorting and grading is highlighted. In India the ever-incre...

Abstract The consistency of inspections is an important requirement official food control. Inconsistency may endanger safety and lead to mistrust in reasons leading inconsistency the mitigation are therefore important. Here we investigated distribution restaurant (n?=?4989) inspection grades from 2014 Finland elucidate for possible differences grades. analyses revealed both regional local overa...

BACKGROUND Food fraud/adulteration has ever increasingly become a dominant food issue of the modern world in both developed and developing countries. It is presumed that globalisation is mainly one of the underlying reasons. OBJECTIVES To assess and analyse the occurrence of food fraud on the Polish market during 2005-2012. MATERIAL AND METHODS Adulteration of foodstuffs was determined from...

Every year tons of fruits are processed in agro and food processing industry. The quality of the fruit plays a vital and is determined by shape, color and size. Manual sorting is one method to sort the fruits that is tedious and takes more time to process. To avoid the above difficulties, automatic sorting and grading can be done using machine vision system. Machine vision methods provide autom...

This paper aims at designing and developing a suitable tool for identifying defects in glass bottles through visual inspection based on segmentation algorithm. Defects are identified in three stages namely Image acquisition, Pre-processing and filtering and Segmentation. In the Image acquisition stage, samples of real time images are taken and are converted into monochrome images. In the Pre-pr...

nowadays cmm machines are widely used in surface measurement and inspection. as inspection results from cmm machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). however, cmm machines give more reliable and accurate results rather than non-contact methods but also these results come with error when ...

The paper presents an economical model for double variable acceptance sampling with inspection errors. Taguchi cost function is used as acceptance cost while quality specification functions are normal with known variance. An optimization model is developed for double variables acceptance sampling scheme at the presence of inspection errors with either constant or monotone value functions. The m...
