Pre-processing In OCR

Pre-processing In OCR

    Pre-processing is a crucial aspect of any OCR (Optical Character Recognition) system, as it enables the extraction of meaningful information from a scanned document. This process involves several steps, such as noise reduction, binarization, and skew correction, aimed at enhancing the image quality and removing any unwanted artefacts that may hinder the recognition process. In other words, pre-processing plays the role of preparing the data for OCR algorithms to accurately recognize and extract text information.


    In general, the success of OCR heavily relies on the precision and effectiveness of pre-processing, making it a crucial component of any OCR pipeline. Advanced pre-processing techniques such as layout analysis and character segmentation have shown promising results in improving OCR performance, pushing the boundaries of what is possible with this technology.
