OCR data extraction technology has been around for quite some time. However, its potential is only just being realized. OCR has the ability to convert images of printed or handwritten text into digital text. Moreover, it can then be easily edited, searched, and analyzed. In the world of business operations, OCR and data extraction are revolutionizing the way data is handled.
With OCR and data extraction, businesses can save time and money. Moreover, it eliminates tedious manual data entry and allows them to access and utilize their data more efficiently. Filestack’s OCR data extraction is one such solution that enables businesses to take advantage of this technology and streamline their operations.
In this blog post, we will explore the benefits of OCR data extraction and how Filestack’s solution can help businesses of all sizes.
What Is OCR Data Extraction?
OCR (Optical Character Recognition) Data Extraction is a technology that enables machines to extract text from scanned documents, images, or other sources. Moreover, it also allows us to convert it into digital data. OCR technology involves an algorithm that uses pattern recognition software to identify each character in an image and convert it into a digital form.
This digital form can be processed by software applications and used for a variety of purposes, such as data analysis, indexing, and search.
Note that OCR and NLP(natural language processing) work together to extract textual data from image files.

What Is OCR Technology?
OCR (Optical Character Recognition) technology is a process that uses algorithms and pattern recognition software to recognize printed or handwritten characters in an image and convert them into a digital form. This data extraction pipeline converts physical documents, such as scanned paper documents or images, into searchable and editable digital files.
Furthermore, it can also help us detect key-value pairs, unstructured or structured data.
OCR Algorithms and Programming Languages
OCR algorithms and programming languages, such as Python and C++, are used to develop OCR software. Moreover, it can recognize and extract text from images. You can use the extracted data for multiple business documents.
Advancements in OCR Technology
The development of OCR technology has seen significant advancements in recent years. It includes the use of artificial intelligence and machine learning algorithms to perform data extraction on printed or handwritten documents.
OCR technology has a wide range of applications, including document scanning, automated data entry, and text recognition in images and videos. Moreover, it is a crucial tool for digitizing paper-based records, enabling businesses to process and manage large volumes of data more efficiently.
What Is OCR Data Extraction Process?
The OCR data extraction work processes in a few simple steps when performing data extraction. Here are those steps:
Steps Involved in OCR Data Extraction
The first step in OCR data extraction is to input the image or scanned document into the OCR software. This can be done using a scanner or by uploading the image file to the software.
Before the text in the image can be recognized, the image needs to be pre-processed to enhance its quality. This involves removing any noise or distortion, adjusting contrast and brightness, and correcting any skew or orientation issues.
The OCR software then uses optical character recognition (OCR) technology to recognize the text in the image. Moreover, the software identifies individual characters and groups them together to form words and sentences.
Data Parsing and Extraction
Once the text is recognized, the software parses the text to identify specific data fields such as names, addresses, and phone numbers.
Post-processing and Validation
The extracted data is then validated against predefined rules and standards to ensure accuracy. Finally, the data can be exported to other applications or databases for further analysis and processing.
Role of Machine Learning in the OCR Data Extraction Process
Machine learning plays a significant role in the OCR data extraction process by improving the accuracy and efficiency of the system. By training the OCR software with machine learning algorithms, the software can learn to recognize and extract data with higher accuracy.
Hence, resulting in improved data quality and reduced manual effort. Machine learning also allows for continuous improvement and adaptation to new data sets, making the OCR system more efficient over time.
What Is Data Extraction Accuracy?
Data extraction accuracy refers to the level of correctness and precision in extracting specific data from a given source. Here are some factors that affect OCR data extraction accuracy.
Factors Affecting OCR Data Extraction Accuracy
Quality of Input Document
The quality of the input document can affect OCR accuracy. Factors such as document age, paper quality, ink quality, and smudges can affect OCR accuracy, as the software may have difficulty recognizing the text on the document.
OCR Software Used
Different OCR software may have different levels of accuracy and performance. Furthermore, some OCR software may be better suited for specific document types or languages. And choosing the appropriate software can impact the accuracy of the data extraction process.
Language and Font
The language and font used in the document can affect OCR accuracy. Therefore, complex languages with unique characters and symbols or fonts with low contrast or unusual spacing can make recognizing the text difficult for the software.
Formatting and Layout of the Document
The formatting and layout of the document also play a role in determining accuracy. Tables, charts, and images can be challenging for OCR software. Moreover, it may require additional processing to extract data accurately.
Note that the columns and headers of your documents can also impact the accuracy.
Techniques for Improving OCR Data Extraction Accuracy
We have listed the two most common ways to improve OCR data extraction accuracy. Let’s explore them:
Correction and Verification
In this technique, we verify the document output that current the errors. Note that we can achieve it using a software tool or manual checking.
