Introduction

OCR-V1 is a single-threaded implementation of the OCR with minimal dependences on other libraries. It provides extensive checks to verify that the application makes correct calls to the OCR API. It also serves as a testbed for experiments with extensions and modifications of the API. The following extensions are available at the moment:

• local identifiers - LIDs are identifiers of OCR objects valid within a task
• labelled GUIDs - alternative to the OCR 1.0.1 proposal, using local identifiers and creator functions to support concurrent creation of mapped objects
• file IO - file support based on existing data block mechanisms
• data block partitioning - dynamic partitioning of data blocks
