Ocr scanners

Types of OCR scanners

The OCR scanner is a machine that takes an image of a document and extracts text from it. The picture can then be saved as a PDF, JPEG, or another format. These OCR scanners are used for archiving and digitizing documents, transforming paper texts into editable and searchable formats.

Optical character recognition has a lot of uses in many industries, and that is why many industries are looking for ways to incorporate it into their workflows. The technology converts different languages and scripts into machine learning text, which helps create searchable databases.

There are different types of OCR scanners, such as: Computer-based OCR, Creeping line, and Segmental.

Computer-based OCR

A computer model is based on the optical recognition of characters. The characters are recognized by pattern recognition and feature extraction. Pattern recognition happens when the scanned text is matched with predefined character patterns, while feature extraction entails analyzing specific features or attributes of a character, such as lines, curves, and angles.

Every character has its own unique combination of features, which helps the OCR software identify and convert the character into machine-readable code. Feature extraction is done after the document is preprocessed to reduce noise and improve clarity.

Creeping-Line OCR

Creeping line OCR is an application that is used to read and process moving text lines. This type of OCR automatically reads and processes the lines of text that are moving, which could be on the bottom of the screen on a television or directly on a conveyor belt in an industrial setup. Line-omni OCR is another name for creeping line OCR.

Segemental

The segmental model breaks the scanned text into smaller text segments, such as characters, words, lines, or paragraphs, which are then processed one at a time. This optical model of the recognition of characters improves the segmentation task by ensuring that every segment is accurately recognized and classified before being reconstructed into the original text format.

Segmentation-based models deal with challenges like overlapping characters, touching segments, and varying segment sizes, thus improving overall accuracy of text recognition. Many of these challenges can arise from poor-quality input or varied text layouts, affecting the reliability of the OCR system.
