Our Customer is one of the world's leading real estate companies with hundreds of offices and hundred thousands of active users.
The Customer wanted to have a native iOS application that would allow scanning any image and easily converting it to black and 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.
To reach the goals, the first step was designing prototype that will take the picture and detect the edges of 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 text on the image.
Here is the list of the features implemented:
Using this app, the Customer significantly reduced expenses on creating PDF documents from arbitrary printed documents. Besides, Mobile scanner app allowed to extract text from any printed document easily.
