How to Extract Data from an Image? Online Extractor
How often have you wished you could quickly digitize information locked within images? With advancements in AI and computer vision, image data extraction is making that a reality.
From signed receipts sitting in folders to medical scans full of diagnostics, images hold a motherlode of value just waiting to be tapped. But manually sifting through each one takes forever.
Luckily, new technologies are emerging that can automatically interpret visual content, understand what it shows, and extract critical details in a way machines understand.
Let’s explore image data extraction. We’ll cover how it works, the types of insights it can provide, and how to get started digitizing your trove of images using leading tools.
What is Image Data Extraction?
Image data extraction uses artificial intelligence and computer vision to comprehend visual content in images. Advanced machine learning algorithms are trained to recognize shapes, characters, objects, and more through pattern analysis.
With this visual intelligence, extraction tools can automatically inspect images and extract structured metadata. Things like text, numbers, geometric measurements, and other identifiable elements are cataloged for easy consumption by other systems and analysis.
It’s like giving machines the ability to visually comprehend just as humans do, then translate those “perceptions” into a digital language our technologies understand. This transformation from unstructured images to structured data enables automated analysis and decision-making at scale.
Why Image Data Extraction is Useful?
The obvious reason is convenience! Manually transcribing information hidden inside vast troves of images is a tedious, error-prone, and unscalable process. Automation not only saves resources but ensures higher fidelity.
Less obvious are the strategic advantages. Extracted data empowers businesses in profound ways:
- Supercharge automation by integrating image data into digital workflows. Extracted data can power robotic process automation, straight-through processing, and other initiatives to optimize workflows.
- Gain real-time insights by analyzing image content at scale. Visual data extraction allows for gathering intelligence from huge volumes of images that existing systems could not previously explore.
- Reduce processing costs while improving quality and turnaround. The automated process is more efficient, consistent, and accurate than tedious manual data entry from images.
- Create new augmented services extracting value for clients. Custom image data solutions can unlock recurring service revenue streams for businesses.
- Uncover hidden connections by correlating visual patterns across databases. Diverse image datasets collected over time can be connected using computer vision to generate multifaceted insights.
- Optimize operations with fact-based visual analytics. Dashboards powered by extracted structured metrics from images facilitate data-driven decisions and continuous improvements.
Types of Image Data
What can be extracted depends on the tool, but here are some common varieties:
1. Text Data (Optical Character Recognition – OCR)
OCR allows textual information to be extracted from scanned documents, receipts, forms, invoices, etc. Some common examples where OCR is used include processing receipts, extracting data from invoices, digitizing medical records, processing invoices, etc. OCR is widely used for processing high volumes of documents in industries like healthcare, finance, logistics, etc.
2. Numerical Data from Charts and Graphs
Image data extraction can recognize chart and graph elements and extract underlying numerical data points. This is useful in domains like market research, medical imaging, finance reports, etc., where visual data representations must be digitized. Advanced data extraction tools make previously hidden insights in charts and graphs interpretable by machines.
3. Object Detection and Counting
Computer vision can detect and count different objects or items in images. For example, counting items in warehouse images, detecting vehicles in traffic camera footage, counting cells in microscopy images, etc. Object detection and counting improves inventory management, directs supply chain operations, and assists medical research.
Introduction to OCR (Optical Character Recognition)
Text extraction via optical character recognition is one of the most useful and ubiquitous forms of image data extraction. So, let’s take a closer look at OCR.
OCR solves the challenge of reading text visually presented in image formats like scanned documents, photos, and videos. It detects character patterns and context to interpret letters, numerals, words, lines, and pages just as the human eye would.
Today’s highly advanced OCR is super accurate even on difficult inputs like poor-quality scans, multi-column docs, or some handwritten text. It’s come a long way since the early machine readers of the past!
Top Popular Data Extraction Tools
There are several dedicated OCR tools and platforms available that make robust optical character recognition very accessible. The following are the top ones to consider:
1. KlearStack
One powerful solution for putting OCR to work is KlearStack, an AI-based document extraction platform. Its OCR capabilities are exceptionally comprehensive.
Template-less and self-learning, KlearStack’s AI intuitively understands context to steadily refine recognition even on unique inputs. It can analyze pages in bulk or individual scans with equal ease, outputting formatted character data.
Besides, KlearStack makes customizing extractors a breeze for optimized accuracy. Simply train models further by highlighting test images the AI got wrong, strengthening its “eyes.”
With seamless integrations and rock-solid security, KlearStack ensures your text insights are securely feeding your critical business systems. Its intuitive interface means professionals of any technical level can apply OCR’s potential right away.
2. Docsumo
For smaller OCR tasks, Docsumo provides an accessible and affordable extraction SaaS. This user-friendly platform gives small businesses the AI edge to digitize essential files.
Docsumo offers pre-built extractors that target common document types like invoices, receipts, and financial statements. So you can immediately recover data from basic scans without configuration.
And since Docsumo’s pre-trained models have learned patterns from vast datasets, extract accuracy remains very high right out of the box for most standard use cases. Any errors can then be corrected interactively and used to retrain models over time.
It seamlessly integrates extraction results into your existing systems, too, via standard API connectors for easy data transfer. This means OCR insights start driving workflows fast.
Extracting Data from Images by using KlearStack OCR
Here are the basic steps to extract text data from images using common OCR tools:
- Sign up tool: Sign up for a free trial on platforms like KlearStack.
- Upload Image File: Select the image file containing text, like a scanned receipt, invoice, or document, from which to extract text. Multiple files can also be uploaded.
