Determination of Concentration for Congo Red Dye Using Colour Image Analysis

Abstract

In this study, Digital images are the main source of information and they are obtained from digital camera which is of low cost when compared to calorimetric discovery. This method involves RGB which consist of Red, Green and Blue colour and Grayscale image analysis consist of Black and White which is used to determine the concentration of the Congo red dye. In this RGB colour image and Grayscale images are equally cropped in square shape using Adobe Photoshop to obtain RGB histogram and Grayscale histogram. From this image analysis, histogram shows the exact accuracy of colour present in the image. The output values obtained from the RGB analysis is used to predict the unknown concentrations of the dyes.
