The only thing which is heavily dependent on accuracy is the quality of the documents used.

OCR (Optical Character Recognition) technology is a system that converts different types of documents, such as scanned paper documents, PDFs, or images captured by a digital camera, into editable and searchable data. It extracts text from these documents, making it possible to analyze, edit, and store the content digitally. OCR works by identifying patterns of light and dark in an image and interpreting them as characters. The technology recognizes the shapes of letters, numbers, and symbols, turning them into machine-encoded text. This is particularly useful for automating data entry tasks, digitizing printed documents, and enhancing document management processes.

OCR technology works in a step-by-step process: 1. Scanning: The document or image is scanned to create a digital copy. 2. Text Recognition: OCR software analyzes the scanned image to detect patterns of text, differentiating them from non-text elements. 3. Character Identification: Each detected text element is broken down into characters using pattern recognition algorithms. 4. Conversion and Editing: The recognized characters are converted into editable digital text, which can then be edited, searched, or processed as needed. This process enables OCR to transform physical documents into versatile digital formats, enhancing data accessibility and efficiency

One of the major challenges OCR faces is around the accuracy of the data extracted. As I mentioned earlier, accuracy is heavily dependent on the quality of documents used. If the documents are blurred, noisy than accuracy would be significantly low.

The main challenge when it comes to OCR is data. Having a proper set of input files available (consistency/identifiable patterns, number, quality) to teach the algorithm is the key to build a solution with high level of confidence, so good results. It is also important to consider the OCR solution has a tool that helps the human in his activity, not something that substitute completely the work the human does. Keeping the human in the loop to supervise and step in should problems occur, is mandatory to ensure the correct performance of the automation in place.

When we talk about challenges we need to track one parameter and that is accuracy. OCR technology may not always recognize the text correctly, especially if the document is of poor quality, has complex layouts, or contains handwritten text. OCR accuracy depends on factors such as the resolution, contrast, brightness, font, size, and language of the text. OCR errors can lead to data loss and misinterpretation.
