# AWS_RecSys
This is a CLIP-Based Fashion Recommender with AWS.
### 📌 Sample Components for UI
1. Image upload
2. Submit button
3. Display clothing tags + recommendations
# Mockup
A user uploads a clothing image → YOLO detects clothing → CLIP encodes → Recommend similar

## Quick Start Guide
### Step 1: Clone the GitHub Project
### Step 2: Set Up the Python Environment
```
python -m venv venv
source venv/bin/activate # On macOS or Linux
venv\Scripts\activate # On Windows
```
### Step 3: Install Dependencies
```
pip install -r requirements.txt
```
### Step 4: Start the FastAPI Server (Backend)
```
uvicorn backend.app.server:app --reload
```
Once the server is running and the database is connected, you should see the following message in the console:
```
Database connected
INFO: Application startup complete.
```

### Step 5: Install Dependencies
Database connected
INFO: Application startup complete.
```
npm install
```
### Step 6: Start the Development Server (Frontend)
```
npm start
```
Once running, the server logs a confirmation and opens the app in your browser: [http://localhost:3000/](http://localhost:3000/)

# What’s completed so far:
1. FastAPI server is up and running (24 Apr)
2. Database connection is set up (24 Apr)
3. Backend architecture is functional (24 Apr)
4. Basic front-end UI for uploading picture (25 Apr)
## 5. Mock Testing for AWS Rekognition -> bounding box (15 May)
```
PYTHONPATH=. pytest backend/app/tests/test_rekognition_wrapper.py
```
<img width="1067" alt="Screenshot 2025-05-20 at 4 58 14 PM" src="https://github.com/user-attachments/assets/7a25a92d-2aca-42a8-abdd-194dd9d2e8a5" />
- Tested Rekognition integration logic independently using a mock → verified it correctly extracts bounding boxes only when labels match the garment set
- Confirmed the folder structure and PYTHONPATH=. works smoothly with pytest from root
## 6. Mock Testing for AWS Rekognition -> CLIP (20 May)
```
PYTHONPATH=. pytest backend/app/tests/test_clothing_tagging.py
```
<img width="1062" alt="Screenshot 2025-05-21 at 9 25 33 AM" src="https://github.com/user-attachments/assets/6c64b658-3414-4115-9e20-520132605cab" />
- Detecting garments using AWS Rekognition
- Cropping the image around detected bounding boxes
- Tagging the cropped image using CLIP
## 7. Mock Testing for full image tagging pipeline (Image bytes → AWS Rekognition (detect garments) → Crop images → CLIP (predict tags) + Error Handling (25 May)
| **Negative Test Case** | **Description** |
| -------------------------------| ------------------------------------------------------------------------------- |
| No Detection Result | AWS doesn't detect any garments — should return an empty list. |
| Image Not Clothing | CLIP returns vague or empty tags — verify fallback behavior. |
| AWS Returns Exception | Simulate `rekognition.detect_labels` throwing an error — check `try-except`. |
| Corrupted Image File | Simulate a broken (non-JPEG) image — verify it raises an error or gives a hint. |
```
PYTHONPATH=. pytest backend/app/tests/test_clothing_tagging.py
```

- detect_garments: simulates AWS Rekognition returning one bounding box: {"Left": 0.1, "Top": 0.1, "Width": 0.5, "Height": 0.5}
- crop_by_bounding_box: simulates the cropping step returning a dummy "cropped_image" object
- get_tags_from_clip: simulates CLIP returning a list of tags: ["T-shirt", "Cotton", "Casual"]
## 8. Run Testing for CLIP Output (30 May)
```
python3 -m venv venv
pip install -r requirements.txt
pip install git+https://github.com/openai/CLIP.git
python -m backend.app.tests.test_tag_extractor
```
<img width="1111" alt="Screenshot 2025-06-06 at 5 12 13 PM" src="https://github.com/user-attachments/assets/d0b3b288-20f8-482f-9d39-dcccf9a775ee" />
Next Step:
1. Evaluate CLIP’s tagging accuracy on sample clothing images
2. Fine-tune the tagging system for better recommendations
3. Test the backend integration with real-time user data
4. Set up monitoring for model performance
5. Front-end demo
