Abstract
A combination of digital camera, computer and graphics software can provide a less expensive and more versatile technique to determine the surface colour of foods. The aim of this work is the development and application of a computer vision system for the measurement of the colour of Iranian sweet bread. In this study, imaging from samples was performed in an environment with 6,500 K illumination standard, and RGB colour space of captured images were transferred to L*a*b* indexes by computer software under illumination standard. This digital image processing was developed as a simple and efficient method for evaluating Iranian sweet bread colour. Also the effect of adding honey on qualitative and quantitative changes of colour values was evaluated as a function of the honey percentage (0, 2, 4, 6, 8, 10, 12, 14% honey powder). Results showed that the colour of the bread produced was improved by adding honey and the developed image processing system was suitable for the measurement of colour parameters. Th...
