Introduction

In the realm of document processing, template matching is more than a buzzword. It's a game-changer, making tasks quicker, more efficient and as easy as pie. So, how do we make it happen? Let me guide you through a seven-step process using Label Studio, coordinates JSON extraction, PDF parsing, and template matching. Buckle up; you're in for an exciting ride.

Label Studio Template Creation

Imagine you're an artist, and Label Studio is your canvas. Alright, perhaps that's a bit dramatic, but you get the gist. Label Studio is a super handy annotation tool that starts this magic- I mean, workflow.
The main agenda? Crafting a template. Consider this your blueprint, the reference guide which will define your document's key areas in the stages to follow. Just like how a chef prepares his mise en place, we're setting things in place to help the process later.

Coordinates JSON Extraction
- Now that you have your Label Studio template, we're going to extract the coordinates JSON file. Sounds technical, right? Don't worry. You're simply extracting the geographic data of your labeled areas.
- Consider the coordinates JSON file as your trusty compass guiding you through this journey. It pinpoints the exact position of your labeled areas and ensures that you're on track for the subsequent steps.

PDF Parsing and Template Matching

Hold onto your hats folks, we're getting into the nitty-gritty. Here, your blueprint (remember the template you created earlier?) really comes into play.
You're now going to read every page of the PDF, one at a time, and match it to your prepared template. Think of it as an ID check at the entrance of a gig. Your template is the face on the ID card, and you're matching it to the person.

Successful Matching and Image Adjustment

Yippee! You've made a successful match. Time for a victory dance? Not quite yet. To ensure accurate extraction of our targeted sections, we need to bring both the template image and the corresponding PDF page to the same dimensions, akin to fitting puzzle pieces.

Cropping Matched Sections

Remember your coordinates JSON, that good old compass? Time to use it again. With its guidance, we'll perform surgical-precision cropping on the identified sections in your matched image. This ensures that the relevant content is isolated well, like segregating veg and non-veg in a buffet line.

Text Extraction from Cropped Sections

With the sections cropped to perfection, we're now going to move to text extraction. It's time to sieve out the content within the cropped areas and prepare it for further examination. Think of this as extracting the juicy tidbits from your favorite crime novel for your book club discussion.
