🎯 Expected Performance (IoU Scores)

Predicted IoU Range: 0.68 - 0.87

Terrain Class	Expected IoU	Confidence
Sky	0.85-0.92	High
Rocks	0.72-0.85	Medium-High
Trees	0.70-0.82	Medium
Dry Grass	0.65-0.78	Medium
Landscape	0.68-0.80	Medium
Bushes	0.62-0.75	Medium-Low

Overall System IoU: ~0.75 (Target for real deployment)

🔄 Workflow - How It Works

Step 1: Image Input

User uploads image → Base64 encoding → Send to Flask backend

Step 2: AI Processing

Flask receives image → YOLO detection → Claude Vision analysis → Generate predictions

Step 3: Detection & Annotation

Draw blue rectangles → Add confidence labels → Calculate IoU → Return annotated image

Step 4: Results Display

React receives results → Display original vs segmented → Show metrics & IoU scores

Built for BigRock Hackathon - Desert Terrain Segmentation Challenge

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
