(1) Two-dimensional scanners are the most common form of scanner and are generally used to record hard-copy (paper) documents. The scanner is to copy paper documents and put them into an electronic form which can be stored in a computer. Computers which have optical character recognition (OCR) software can read text from the scanned document and change it into a text-file format. This means the scanned image can now be edited by a word processor such as MS Word. If the original document was a photograph or image, then the scanned image forms an image file such as JPEG. (2) 2D scanners have many uses. One important use is at airports to read passports. They make use of OCR technology to produce digital images of the passport pages. Because of the OCR technology, these digital images can be used in a number of ways. For example, the OCR software is able to review these images, select the text part and then automatically put the text into the correct fields of an existing database. It is possible for the text to be stored in ASCII format. It all depends on how the data is to be used. At many airports the two-dimensional photograph in the passport is also scanned and stored as a JPEG image. The passenger’s face is also photographed using a digital camera. The two digital images are compared using face recognition\detection software. What does Paragraph (1) say about optical character recognition technology?
