Artificial  Intelligence  (AI)  is  used  in  various  areas  in  real  life  like  character  recognition,  face
            recognition,  speech  recognition,  and  many  more.  With  the  use  of  AI, some  of  the  technologies
            become very powerful. In this chapter, we will discuss how AI works in some of the applications.

            Optical Character Recognition

            Optical Character Recognition (OCR) is a technique to convert an image of text or physical document
            into editable form. It is also known as text recognition.



























            How Does OCR Work?

            Now, let us understand the steps involved in any OCR program:
            1.  A paper document is read by a scanner and converted into a machine-readable form.

            2.   The letters, numbers and symbols are examined by OCR. It identifies the patterns, uppercase and
               lowercase, etc.
            3.  At the end, OCR process the characters and converts them into computerised files.

            Role of AI in OCR
            Before  the  invention  of OCR, converting  physical  text  documents  to  digital  was  done  manually.
            It was a time-consuming process, and several retyping were required to make it error-free. With
            OCR, the task has become easy. Once the document is converted into digital form, editing is easy.
            With artificial intelligence (AI), handwriting interpretation has become accurate. AI is playing an
            important role in the effectiveness of OCR. It ensures that these documents are converted with the
            greatest possible accuracy.

            Areas Where AI-Powered OCR is Being Used

            There are various areas where AI-powered OCR is being used. Some of them are as follows:
               • Document are scanned using OCR.

               • Robots use OCR to scan barcodes in the warehouses and find stock.
               • In bank, AI-paired OCR technology is used to scan a cheque from the front and back, validate it
               and match it with the amount you deposit in the account.
