Identify business cards
The camera automatically identifies and creates a blue border around the card in order to enhance the accuracy of the image when capturing. To achieve the best results, a business card with bright colours should be placed on a dark background and vice versa.
Border detection and cutting
The captured image will be processed to detect border and cropped the card out of the image.
A contact information will automatically be generated based on the content of the business card. Once it gets approved to create and save, the contact will appear in the phone's contact list.
The application supports Vietnamese and English languages that can be selected in accordance with the business card before extracting content.
