OCR

Optical character recognition (OCR) is process of classification of optical patterns contained in a digital image. The character recognition is achieved through segmentation, feature extraction and classification.

Optical character recognition (OCR) refers to both the technology and process of reading and converting typed, printed or handwritten characters into machine-encoded text or something that the computer can manipulate.

Optical character recognition is the recognition of language-specific characters by a computer by analyzing an image, which is already computer-readable. This is often done by taking an image of the document first by scanning it or taking a digital picture. This creates a raster image made up of data that the computer understands, and through specifically programmed algorithms, most of which are used in the field of artificial intelligence, the computer recognizes the patterns in the image, and in this case the patterns are characters. The program then creates or outputs character codes, usually ASCII, that are equivalent to the recognized characters from the input image.
