Tesseract is a C++ open source OCR engine. We expect that it will also be an excellent OCR system for many other Intended for high-throughput, high-volume document conversion efforts. OCRopus is development is sponsored by Google and is initially High-performance handwriting recognizer developed in the mid-90's andĭeployed by the US Census bureau, and novel high-performance layout The OCRopus engine is based on two research projects: a Large scale machine learning for addressing problems in documentĪnalysis, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, and multi-lingual capabilities. OCRopus™ ( FAQ) (written in Python, NumPy, and SciPy) Open many different image formats, and its quality have been improving Makes it very easy to port to different OSes and architectures.
