Java™ Web Start ( download JDK 7 or later). Here's a sample JSON output where OCR is applied after extracting the keys and the values.Click the Launch button to run SimpleTableDemo using We'll also have to make sure that this algorithm is applicable for different templates, as in the same algorithm should be appropriate for documents of other formats. Now, the goal of key-value pair extraction is to identify these labels (Keys) and the values associated with it. Here, there are specific fields where labels like DOB, ISS, Street Address, Sex, Eyes etc. Key-value pair extraction is a technique used commonly for documents to identify the location of particular fields in form documents from block objects and then later stored in a map.
Key-Value Pair Extraction for Passports and ID Cards In the next section, we’ll look into the key-value pair extraction in documents.
For more information on OCR techniques and tools, read our blog on OCR with OpenCV and Python here. These algorithms should help OCR for key-value pair extraction, image augmentation (making sure the scanned images are consistent and aligned correctly), multilingual text extraction etc. Hence, we'll have to make use of machine learning and deep learning algorithms to make OCR more intelligent. Input Image on Left, Text Extracted from Tesseract OCR on RightĪlright, it's now evident that OCR alone cannot perform efficiently for processing different documents types. To make this more simple for you here is an output of Tesseract OCR when performed to a driving ID. Nevertheless, OCRs are not intelligent their only goal is to extract text wherever identified. For example, consider our problem of extracting information from Passports and ID cards, here we'll be needing only a few essential attributes like Name, ID Number, Sex, Age and Address. They blindly extract text from given images without any processing or rules. However, even popular tools like Tesseract fail to extract text in some complex scenarios.
Java ocr tool software#
It's an open-source python-based software developed by Google. Out of these, one popular and commonly used OCR engine is Tesseract. The OCR techniques are not new, but they have been continuously evolving with time. Lastly, we'll discuss how these OCR models can be trained more efficiently and use them as an id/passport scanner online API within your app using Nanonets.
Java ocr tool code#
In this blog, we'll be discussing how developers and companies can automate information extraction for KYC documents, including reading complex fields like mrz code Additionally, we’ll also review the challenges that need to be addressed during the process to create an MRZ passport reader. If you're not aware of this, think of it as a computer algorithm that can read images of typed or handwritten text into text format. Hence, to make this process efficient, most of the people use Optical Character Recognition (OCR). To digitalize these, the reviewers have to manually verify and then type down information like name, address, and enter it into databases or ERP systems, which is a hectic and time-consuming task. In several organizations, details from documents like Passports and ID Cards are often manually noted down or captured to submit copies for KYC tasks.
