Aplicativo Android para classificação de fitas indicadoras de pH

PH is one of the main quality indicators used in several industries such as food, beverage and water treatment. Some pH measurements methods are more affordable than others and can be easily used by anyone. The pH test strips can be highlighted as one of the best techniques. At the same time, this kind of analysis relies on the human vision condition that may be compromised in some cases due to aging, eye fatigue or vision-related diseases. This work presents the development of an Android app capable of classifying a pH strip according to its reference chart using image processing techniques.
