OCRtekniikka

OCRtekniikka, a Finnish term, translates to Optical Character Recognition technology. This technology is a form of artificial intelligence that allows computers to recognize and extract text from images. Essentially, it converts scanned documents, photographs, or any image containing text into machine-readable data.

The process typically involves several steps. First, the image is preprocessed to enhance clarity and remove noise. Then, segmentation is performed to separate individual characters or words. Next, feature extraction identifies unique characteristics of each character. Finally, pattern matching or neural networks are used to compare these features against a database of known characters and determine the most probable match.

OCRtekniikka has a wide range of applications. It is crucial for digitizing historical documents, making them searchable and accessible. Businesses use it for processing invoices, forms, and other paper-based data, significantly reducing manual data entry. In accessibility, it enables visually impaired individuals to read text from images. It also plays a role in passport and ID card scanning, as well as in translation software that can extract text from images. The accuracy of OCRtekniikka has improved dramatically over the years, making it an indispensable tool in many fields.
