The OCR stands for optical character recognition. The technology uses advanced AI techniques to extract text from all type of images. The computers recognize the selected text as binary codes, understand its meaning, and then convert in again into comprehendible human speech.
The most common method used to convert binary into text or vice versa is ASCII, American Standard Code for Information Exchange. The code has binary conversions for every English Letter and Number.
The computer understands any text by identifying this pattern. This code makes conversion faster and quicker. It encoded binary values for 128 special characters including letters, numbers, and additional marks.
Here is how the chart looks:
The OCR has shown 90% accuracy in extracting the right information. The global OCR market currently stands at 10.65 Billion USD.
