Product Reviews for LEADTOOLS Recognition Imaging

Updating 1980’s Technology with the Help of 2017’s Imaging Tools

"The solution that was most accurate and started working for me, a relative newbie with OCR technologies, was the LEADTOOLS OCR Advantage Module."

LEADTOOLS Recognition Imaging SDK: Create Imaging Apps Easily

"LEADTOOLS Recognition Imaging SDK powered by the LEADTOOLS Advantage OCR engine - I had the pleasure of taking the SDK for a spin, and let me tell you it was well worth it. LEADTOOLS has already established itself as the leader in Imaging SDKs, but for me it goes much further than just that. The technical support is stellar! This is what differentiates a good, functional product from a stunning product."

Image OCR and Document Conversion using the LEADTOOLS SDK

"The problem I am looking to solve while evaluating the LEADTOOLS SDK is to use a photo of a hard copy page of text taken with my phone, have it processed and displayed in the document viewer, then have it converted to Word format so that it can be easily edited. This can come in handy when only hard copies of a document are available, and a digital format is requested."
