With so many powerful OCR applications available, choosing the right one for you can be confusing.
Use this guide as your first step, offering a brief explanation of the basic capabilities of each product covered.
So, let’s jump right into it:-
OCR (Optical Character Recognition) software is a revolutionary way to extract text from images. By using OCR, you can automate many time-consuming and manual data entry tasks and gain access to previously difficult-to-reach sources of information.
Nowadays, advanced programs like Docsumo have solved this problem by using machine learning to make the process of scanning and correcting documents much more accessible. Using OCR can make your life much easier and help increase productivity in the workplace for various reasons.
Let's take a closer look at the process:
OCR software is a program that can read text from images, scanned documents, PDF files, or live feeds. The goal is to make the data more readily available for storage and manipulation in your computer system. In most cases, this requires further processing before it can be used for anything meaningful (for example, you can scan a document but then need to extract certain words or numbers from the resulting file).
OCR automates scanning capabilities allowing it to scan paper documents, turn them into an electronic format, and then store them in an electronic document management system (EDMS).
The business world has seen a radical transformation in how it operates in the last two decades. The advent of the Internet and its pervasive use have led to tech innovations that have changed the face of business. OCR software is one such innovation that has made a massive difference in how we work.
The OCR workflow consists of several steps executed in series and preparing the image for recognition. OCR software uses advanced algorithms to read and analyze the document, identify text lines and characters, and convert them into machine-encoded text. This machine-encoded text can then be used as searchable content.
The base of this process is the scan or photograph of the document. When scanning, all pages must be examined in one step, making it easier to correct errors in the following process steps:-
The first step is to capture the image. This is usually done with an OCR software scanner but can also be done with a digital camera. The image is then stored as a bitmap or raster image. Each pixel contains color and brightness information for that point on the page in this format. Bitmap files come in many formats, such as TIFF, JPEG, and PNG. The format used will depend on the application intended for use with the OCR software.
The next step is to apply a set of image processing algorithms to improve the quality of the image before recognition. The step includes pre-processing the image file (or scanned page) by applying noise reduction, de-skewing, binarization, and other techniques, depending on the quality of the original image and the software's capabilities.
These algorithms include:-
Binarization -This process converts the entire image into monochrome black and white (grayscale). For example, a halftone photograph may have different shades of gray. In this case, binarization converts various shades of gray into absolute black or white pixels. This simplifies later processing by breaking down the image into just two colors.
Noise Reduction - It is done to get rid of pixels carrying out false information that could affect the extraction.
De-skewing - To rotate a scanned image to get rid of any skewing.
Once the image has been pre-processed, an automated document analysis step tries to detect the type of document being processed. This helps determine how the rest of the OCR process proceeds. For example, if a scanned image is identified as an invoice or purchase order, certain assumptions can be made about what type of data to expect from that document and how it ought to be structured.
This is where the OCR software analyzes and identifies the type of content in the document. It does this by looking for sections of text that are similar to each other to form what's called a "cluster of characters" or "glyph cluster".
Once a template is created based on the whole document, individual fields can be extracted. This is done by segmenting the document into smaller sections containing specific information types (like an address or a phone number). This step may also include keyword recognition. This is done by examining gaps between words or lines of text and making an educated guess based on what it knows about the standard letter.
In this step, OCR software separates each data field (e.g., name, address, etc.) on a document into different zones to be handled separately by extraction tools in the next step.
These algorithms can analyze how many times a particular pixel pattern occurs in an image. The more frequently this pattern appears, the higher chance that it is part of a word. Some OCR software even has pre-trained models to detect specific symbols like digits or punctuation marks.
This step involves extracting all relevant data from each segmented area and putting it into a usable format for your business. Extracted data can be exported to other databases or applications for further processing.
The engine extracts the document's information like headers, footers, and page numbers. It also determines the structure of columns and tables.
Once the images are segmented into lines, words, and characters, they're ready for recognition. During this stage, data is extracted into usable information by comparing the segments against an OCR engine or machine learning model that's been trained on thousands of examples.
OCR software extracts data from each zone with built-in machine learning models or custom models depending on your organization's specific needs.
Now that all of your data has been extracted and stored, you can use it for further use. However, before using it, you must recheck any mistakes in the extracted data. If there are mistakes, you can correct them before using them for your work.
While most OCR engines do an excellent job on their own, some will have you manually look over each document's output before submitting it for processing. Even if the OCR software is highly accurate, there will still be errors that require human validation. This step ensures that the final results are error-free.
Different industries have different requirements, and additional requirements call for various software. To make this choice more manageable, we have compiled a list of things you need to consider when looking for the best OCR software for your business.
The scalability of the OCR software is one of the most critical aspects when choosing an OCR solution. The OCR software should grow with your business so that you don't have to invest in new software every time your business expands.
Data extraction using OCR is not always 100% accurate as some words may be misread while converting them, leading to errors in your document. The best way to deal with this problem is by using an OCR solution that has a high accuracy rate.
An OCR software should integrate well with business processes as it helps in automating a range of tasks. The software should have the ability to be interconnected with third-party applications and incorporated into the existing business processes. This eliminates the need to do manual data entry, thereby reducing the cost of operations.
The OCR software should be integrated with other business-specific applications such as document management systems, accounting software, CRM, and others to streamline their processes and improve efficiency.
Businesses need to leverage analytics and adequately use the data for growth in this digital age. So, choose a tool that can analyze unstructured data and provide you with actionable insights based on it. Any analytics tool must provide meaningful visualizations so you can understand your data at a glance and make better decisions. Make sure the software you choose offers a centralized dashboard where you can view visualizations of all your data in one place.
An OCR software may not work with all types of documents and may require customization according to your needs. So, make sure that the solution provider offers customizable solutions as per the outlined requirements.
In this section, we discuss the parameters you should specifically be looking at depending on your industry while choosing an OCR solution:-
