This guide walks you through a simple real-time text capture scenario, in which the user points the device's camera at the text to be recognized.
The purpose of Real-Time Recognition SDK for Android OCR development is to enable your application to capture information directly from the smartphone camera preview frames, without actually snapping a picture. Once you start capturing, the Real-Time Recognition SDK engine will automatically request new camera frames and process them, using each new frame to verify and improve the recognition result from the previous frame. This process is continued until the result reaches the required stability level. Combining several images enables Real-Time Recognition SDK to recognize text even in situation when it is hard to obtain a still photo of suitable quality for recognition.
Note that Real-Time Recognition SDK also supports recognizing text on an image that was already saved to a file, which allows it to process existing photos, scanned texts, and so on. See Recognize Text on Photos for the description of this scenario.
Note: Before you begin, see Build your application with the OCR library for iOS.
To implement the real-time text capture scenario, follow these steps:
