Provides access to low-level functions for single image processing. Useful when you need to recognize an image that was not taken by the camera of the device on which the application operates — for example, scans sent by email.
Note: This interface is available only in the extended version of the library.
Use the object on the thread on which it was created; you may also create several objects on different threads and use them concurrently. All method calls are synchronous (will not return until the operation is completed), so should not be used on the UI thread.
