Abstract [sv]

Flera nya tjänster som Mina utgifter och Smartbudget vittnar om ett tilltagande intresse bland konsumenter att planera sin ekonomi. Matvaror utgör en stor del av det genomsnittliga hushållets budget och är därmed en kostnadspost som kan göra stor skillnad i hushållets ekonomi.Detta examensarbete ska undersöka möjligheten att jämföra matvarors pris på olika affärer med hjälp av en Android-applikation och genom att fotografera texten på kvitton. Texten kommer sen processas och sorteras för att få ut nödvändig data som sen kan sparas undan i en databas. Färdiga Algoritmer och OCR-motorer har utvärderats och implementerats i applikationen direkt genom så kallade C-Bibliotek. Dessa gör det möjligt att utan större problem vidareutveckla applikationen för iOS eller Windows Phone.Projektet och Android-applikationen visar på möjligheterna att använda färdiga C-bibliotek samt telefoners kamera för att enkelt sålla ut och spara undan den informationen som är relevant för konsumentens del.

Abstract [en]

Multiple new services such as “Mina utgifter” and “Smartbudget” show that there is an increased interest among consumers to plan their economy. Groceries represent a large part of the average households budget and is thereby an important thing that can make a large difference in every households economy.This thesis will examine the possibilities to compare food prices with help of an Android application and by taking pictures of the text on receipts. The text will then be processed and sorted to get the necessary data which later can be saved into a database. Premade algorithms and OCR-engines have been evaluated and implemented directly into the Android application by using so called C-Libraries. This makes it possible without major efforts to further develop the application for IOS or Windows Phone.This project and the Android application show the possibilities to use premade libraries and the phones camera to extract and save the necessary information that is relevant for consumers.
