![]() ![]() Text detection: First, the computer vision model detects the regions of interest in the input image that may contain text. The preprocessing may include resizing, contrast enhancement, binarization, noise reduction, and other techniques.ģ. Image pre-processing: The input image file is preprocessed to enhance the quality of the image to provide better recognition. ![]() For instance, if there's a printed document on a piece of paper, the scanner creates a scanned document - a digital copy (image file) of the same document.Ģ. Hardware part: The process typically starts with the hardware component, which is any type of optical scanner or specialized circuit board that captures the physical shape of the original document and turns it into a digital image. Now let's briefly describe the steps that are usually used in modern OCR software, some of which could not be used in optical character recognition systems.ġ. Script recognition is a specific application of OCR that focuses on transcribing cursive and script handwriting. Intelligent Character Recognition (ICR): OCR systems can recognize and transcribe handwritten or cursive text from scanned documents, making it possible to digitize handwritten notes, letters, and forms.OCR can recognize text in images captured under various conditions, such as low light, blurry images, or images with non-uniform backgrounds, making it useful for tasks such as recognizing text from street art or identifying text in images captured by drones. Scene text recognition: Recognizing texts from natural scenes such as street signs, storefronts, or license plates.It could also simplify the task of invoice processing, and financial record keeping, and many business document recognition tasks are solved this way. This approach is widely used to automate the processing of legal documents, and extraction of data from bank statements and invoices. It enables users to extract information from old printed documents and integrate them into modern workflows. Scanned document recognition: Printed documents are scanned and then OCR software converts scanned documents into searchable and editable texts.OCR can perform a range of tasks, including: Moreover, Optical Character Recognition (OCR) technology has transformed how we digitize and process documents. Once this is done, the information obtained from OCR may be applied to a vast array of uses that range from personal use to public security. With OCR, we can encode printed text from an image, allowing it to be electronically altered, searched, stored more compactly, presented on the web, and utilized in machine processes like cognitive computing and more. It is a field of study in artificial intelligence that is tied to computer vision and pattern recognition. Optical Character Recognition refers to the process of extraction and conversion of a handwritten or typed text from an image, video, or scanned document like PDF to a digitally modifiable format (txt, docx, etc). What is OCR (optical character recognition)? Advantages & limitations of OCR software.Did you know that all of this is possible thanks to optical character recognition (OCR)? Let's dive into the basics of OCR, how it works, the problems it solves, and why it's an integral part of modern technology for now and decades to come. Similarly, when you receive a PDF document and can't copy any of the text, you opt to convert it to a different file type instead. We've all been there - standing in the grocery store holding a product that's written in a foreign language, waiting for our smartphone camera to scan the text and give us a translation so we know exactly what we're looking at. ![]()
