OCR solutions help health institutions with the various functionalities that help them in implementing OCR technology and using its various functions that are given below:

Character Recognition

OCR solutions use advanced artificial intelligence algorithms to recognize characters, symbols, and patterns within scanned documents and images with enhanced accuracy, irrespective of font style and size. As a result, healthcare institutions experience seamless and accurate text recognition capabilities across all document types.

Text Extraction

In case the scanned document or image is of poor quality or has distorted text, OCR solutions help in precise text extraction from documents, leading to the effortless conversion of the scanned text or image into searchable and editable format.

Document Classification

OCR solutions also have the ability to classify your documents based on predefined criteria such as document type, patient identifier, or medical specialty.

This function helps in efficient organization and quick retrieval of patient records, leading to improved patient care and streamlined workflows.

Data Verification

OCR technology uses sophisticated verification mechanisms that verify the extracted data against predefined templates or databases to ensure that the patient information is accurate and consistent.

As a result, there is a minimisation of errors and mitigation of risks associated with manual data entry.

Data Validation

OCR solutions play an important role in validating the extracted data for various aspects like completeness, integrity, and compliance with all the required regulatory standards for the healthcare industry, such as HIPAA (Health Insurance Portability and Accountability Act).

By incorporating and implementing data validation rules, OCR solutions help in the maintenance of data accuracy and integrity across the entire process of records management.

Handwriting Recognition

Advanced OCR systems use machine learning algorithms to accurately recognize and interpret handwritten notes or prescriptions. By digitizing handwritten documents, OCR eliminates the need for manual prescriptions, leading to improved accessibility to patient records and medical history.

How Does OCR Solution Work?

Let us now understand the various steps in the working of the transformative technology of OCR Solutions:

Image Acquisition

The process of OCR solution starts with the acquisition of high-quality images of documents by using scanners or digital cameras. By obtaining an optimal image that has clarity and legibility, there is a higher accuracy rate in text recognition.

Preprocessing

The images that are acquired undergo preprocessing techniques such as noise reduction, skew correction, and contrast improvement to enhance readability and OCR accuracy.

Further, the preprocessing step optimises image quality and prevents the common risks that are associated with document scanning.

Text Detection

OCR solutions use OCR algorithms to analyze and detect the text region in the preprocessed image. OCR systems identify the text blocks within the image by using various techniques like edge detection and contour analysis.

Character Segmentation

The text regions that were identified in the previous step undergo segmentation into individual characters or words in order to prepare the scanned image for text recognition.

With the help of character segmentation, OCR algorithms can isolate text elements for accurate recognition and interpretation.

Feature Extraction

After character segmentation, OCR software extracts distinctive features from the characters, such as size, shape, stroke patterns, and many more to create various character descriptors.

With the help of feature extraction, the pattern recognition algorithms get an input that helps in developing strong character recognition capabilities.

Character Recognition

OCR solutions match the extracted features from the previous step with predefined character templates by using pattern recognition algorithms such as neural networks.

The process of character recognition involves comparing the character descriptors with predefined templates and selecting the best match, which leads to the accurate identification and classification of characters.

Post-Processing

To enhance the accuracy and readability of the recognized text, the recognized characters undergo post-processing techniques.

The postprocessing techniques include error correction mechanisms, context analysis, and language modelling to improve OCR outputs and the quality of text recognition.

Text Reconstruction

After completing the process of character recognition, the recognized characters are again reconstructed into machine-readable text while preserving the layout and formatting of the document.

With the help of the OCR solution, the document is presented in its original form and structure while maintaining the readability of the digitized content.

Output Generation

The final output generated after completing the entire character recognition process, including text reconstruction, includes an editable and searchable document, which helps users to change the document, search from it, and analyze the digitized document in an effective and efficient manner.
