Our customer is one of the world's leading real estate companies with hundreds of offices and hundreds of thousands of active users.
The customer wanted to create a native iOS application that would allow scanning any image and easily converting it into black&white PDF document. It should include an OCR feature for text recognition using two languages — English and Spanish. Besides, the scanner application should be integrated with the customer’s electronic document management system.
The first step was designing a prototype that would take a picture and detect the edges of a white sheet of paper. Next phase was designing convenient UI controls and implementing all other features. Using open source libraries (Tesseract SDK and OpenCV framework) ensured efficient processing of images — detecting document corners, transforming to original proportions, recognizing the text on the image.
Using this app, the customer significantly reduced expenses on creating PDF documents from arbitrary printed documents. Besides, the mobile scanner app allowed to extract the text easily from any printed document.
