OCR vs IDP

What Is OCR

OCR stands for optical character recognition. It is a technology that scans documents. It primarily deals with information captured visually from scanned documents, invoices, or images.

Therefore, you don’t need to worry if you have a scanned PDF of a contract or a picture of a receipt. It can quickly turn an image into a text format that you can edit, search, and change electronically. This minimizes the need for costly, error-prone manual data entry.

How It Works 

How does OCR Work

OCR is a remarkable technology that converts text from static images to editable digital text. It adheres to a few procedures.

    1. Preprocessing: The image must be ready for character identification in the first phase. This might involve altering brightness and contrast, reducing noise from the image (such as dust or speckles), and turning the image to black and white so that it can be more easily analyzed.
    2. Text Segmentation: Once the image is prepped, OCR software needs to identify the actual text regions within the image. This might involve separating text from the background and potentially segmenting lines of text into individual characters.
    3. Character Recognition: OCR engine uses two main approaches for character recognition.
      • Pattern Matching: The software compares the shapes and features of characters in the image to a database of known characters. It essentially tries to find the best match between the image and its stored templates of letters, numbers, and symbols.
      • Feature Extraction: This approach analyzes the individual components of a character, like lines, curves, and endpoints. The OCR engine can reconstruct and recognize the character by identifying these features.
    4. Post-Processing: In the last step, before giving a final output of the text, it will carry out some post-processing techniques after character resignation in an image or document. This will help guarantee that the information provided is accurate and grammatically correct and that no errors are made in the detected text.

OCR Applications

OCR technology opens endless possibilities for businesses and individuals alike. Here are five key areas where this technology shines

  1. Digitizing Paperwork: OCR is an innovator for businesses with a heavy paper load. It allows for the scanning of, contracts, receipts, small business invoice templates and other documents to be converted into searchable digital files that can be edited. This eliminates the need for physical storage of documents and creates a more paperless working environment.
  2. Accessibility for All: By transforming scanned documents or text images into digital formats that text-to-speech software can read aloud, optical character recognition (OCR) facilitates people with visual or reading impairments. This shuts down the access gap and guarantees that this information is available to all.
  3. Simplifying Data Entry: Entering data is time-consuming and prone to mistakes. OCR automates this process by removing text from business cards, forms, and other documents with fillable fields. This saves a lot of time, decreases human error, and refines data collection.
  4. Boosting Research and Archiving: OCR breathes new life into historical documents, archived newspapers, or handwritten manuscripts. It easily converts them into digital text, which allows researchers to search and analyze vast amounts of information.  It’s the best when accelerating the pace of discovery and historic preservation.
  5. Supercharging Mobile Apps: OCR is making its way into mobile apps, allowing users to scan documents. Imagine capturing a receipt with your phone’s camera and instantly having the digital text for expense reports or warranty claims. It empowers mobile applications with powerful document processing capabilities.

What Is IDP

IDP stands for Intelligent Document Processing. It’s the next level up from OCR, adding a layer of intelligence to further automate document processing.  It can extract text from documents just like OCR, but it goes beyond that.

IDP recognizes characters, but it also understands a document’s overall structure and layout. This allows it to identify different sections, such as invoices, addresses, or product details on a form. It extracts text and data hidden within documents. For example, it can pull out dates, currency values, or even specific keywords based on pre-defined rules.

So, while OCR focuses on converting images to text, IDP takes that a step further by transforming documents into structured data that is easily integrated with other business systems or applications.

How It Works 

what is IDP and how its work

In Intelligent Document Processing (IDP), OCR technology is expanded to produce a more advanced document processing system. Here’s a breakdown of how it works.

  1. Document Ingestion: Similar to OCR, IDP starts by ingesting the document, which can be a scanned image, a PDF file, or even an email attachment.
  2. Advanced Preprocessing: While OCR focuses on basic image cleaning, IDP goes deeper. It might analyze the document layout, identify different document types (invoices, receipts, etc.), and even perform techniques like form extraction to separate specific sections.
  3. Intelligent OCR and Character Recognition: IDP integrates OCR to extract text from the document. However, it goes beyond simple character recognition. It handles complex layouts, handwritten text (with higher accuracy than OCR alone), and potentially even different languages.
  4. Data Classification and Extraction: This is where IDP truly shines. Using a combination of techniques like machine learning and pre-defined rules, It analyzes the extracted text and classifies it into meaningful categories. It also helps identify specific data points like names, addresses, invoice numbers, or any other relevant information based on the document type.
  5. Data Validation and Correction: IDP doesn’t just blindly extract data. It often employs data validation techniques to check for inconsistencies or errors. It might cross-reference extracted information or use fuzzy logic to identify potential mistakes. This helps ensure the accuracy of the extracted data.
  6. Data Export and Integration: The final step involves exporting the extracted, structured data into a usable format. This could be a CSV file, integration with enterprise resource planning (ERP) systems, or feeding the data into workflow applications. IDP essentially transforms documents into valuable, machine-readable information.

IDP Applications

Intelligent Document Processing (IDP) transcends the limitations of OCR, offering a powerful suite of functionalities for businesses. Here are five compelling applications that showcase the transformative potential of IDP.

  1. Automating Accounts Payable (AP): Imagine automatically processing invoices. IDP can extract key information like vendor name, invoice number, line items, and total amount. This eliminates manual data entry, accelerates invoice processing, and reduces the risk of errors.
  2. Streamlining Customer Onboarding: New customer applications often involve mountains of paperwork. IDP can extract data from ID cards, passports, or utility bills, populating customer information systems and expediting onboarding.
  3. Enhancing Loan Processing:  IDP can automate loan applications by extracting relevant data from financial documents like tax returns, pay stubs, and bank statements. This speeds up loan processing times and improves the overall customer experience.
  4. Supercharging Insurance Claims: Processing insurance claims can be a tedious task. IDP can extract details from accident reports, medical records, and receipts, streamlining the claims process and ensuring faster payouts.
  5. Boosting Data Analytics: IDP unlocks valuable data trapped within documents. IDP feeds data analytics tools by extracting structured information, enabling businesses to gain deeper insights, identify trends, and make data-driven decisions.
