NETRA Project Cleanup Analysis

Files & Folders That Can Be Removed Safely

Last Updated: April 17, 2026
Analysis Status: Complete

---

📊 Summary

Your project has undergone a refactoring from a monolithic NETRA/ structure to a modular src/ structure. Many old files remain unused but do not affect the working code.

Total Unused Items: 9 folders/files
Estimated Space Saved: ~150-300 MB (depending on venv and model files)

---

🗑️ SAFE TO DELETE (No Impact on Running Code)

1. NETRA/ Directory ⭐ HIGH PRIORITY

Status: ❌ NOT USED (replaced by src/)

Contains:

• anomaly_detector.py → Replaced by src/detectors/anomaly_detector.py
• violence_detector.py → Replaced by src/detectors/violence_detector.py
• weapon_person_detector.py → Replaced by src/detectors/weapon_person_detector.py
• yolo_detector.py → Replaced by src/detectors/yolo_detector.py
• video_capture.py → Replaced by src/pipeline/video_capture.py
• requirements.txt → Superseded by root requirements.txt
• __init__.py → Replaced by src/__init__.py
• mian_cctv.py → Legacy standalone script (not used by webapp)
• check_env.py → Legacy diagnostic script
• test_violence_model.py → Legacy test script

Why It's Unused:

# webapp/app.py ONLY imports from src/ (lines 22-27)
from src import (
    ViolenceDetector,
    YOLODetector,
    WeaponPersonDetector,
    PoseDetection,
    AnomalyDetector,
    VideoCapture,
)

Safe to Delete: ✅ YES

---

2. detection logic/ Directory ⭐ MEDIUM PRIORITY

Status: ❌ NOT USED (replaced by src/detectors/)

Contains:

• pose_detection.py → Replaced by src/detectors/pose_detector.py
• __pycache__/ → Compiled Python cache

Why It's Unused:

• The app imports PoseDetection from src.detectors, not from detection logic/
• This appears to be an intermediate development folder

Safe to Delete: ✅ YES

---

3. database/models/ Directory ⭐ LOW PRIORITY

Status: ❌ EMPTY & UNUSED

Contains:

• Nothing (empty directory)

Why It's Unused:

• No files in this directory
• No references in the codebase
• Was likely planned for database model definitions but never implemented

Safe to Delete: ✅ YES (empty)

---

4. models/ Directory ⭐ MEDIUM PRIORITY

Status: ⚠️ DUPLICATE (redundant copy of ai_models/)

Contains:

• anomaly_detection/ (empty or duplicate)
• object_detection/ (duplicate of ai_models/object_detection/)
• pose_detection/ (duplicate of ai_models/pose_detection/)
• violence_detection/ (empty or duplicate)
• weapon_detection/ (duplicate of ai_models/weapon_detection/)

Why It's Unused:

• Config loads models from ai_models/, not models/
• See config/model_config.py - specifies ai_models/ as primary path
• This is a redundant copy consuming disk space

Safe to Delete: ✅ YES (but verify no other config references it)

---

5. tests/ Directory ⭐ LOW PRIORITY

Status: ❌ EMPTY & UNUSED

Contains:

• Nothing (empty directory)

Why It's Unused:

• No test files exist
• Not integrated into any CI/CD pipeline
• No pytest or unittest setup

Safe to Delete: ✅ YES (empty)

---

6. test_migration.py ⭐ LOW PRIORITY

Status: ❌ OBSOLETE (one-time migration script)

Purpose: Verifies migration from old NETRA/ to new src/ structure
Used By: Was run once during refactoring, no longer needed

Why It Can Be Deleted:

• One-time setup/migration verification script
• Not part of normal application flow
• Safe to remove after verification completed

Safe to Delete: ✅ YES

---

7. .sixth/ Directory ⭐ LOW PRIORITY

Status: ❌ BUILD/CACHE FOLDER

Likely Contents:

• Third-party/IDE build artifacts
• Not version-controlled in standard .gitignore

Safe to Delete: ✅ YES (rebuild will recreate if needed)

---

⚠️ ENVIRONMENT FOLDERS (Delete If Local Machine Only)

8. venv/ Directory ⭐ HIGHEST SIZE IMPACT

Status: 📦 LOCAL DEVELOPMENT ONLY

Size: ~100-300 MB (depending on installed packages)

Note: Should NOT be in version control
Check .gitignore: Already listed as excluded (line 4)

Safe to Delete: ✅ YES (if you have requirements.txt)

• Recreate with: python -m venv venv then pip install -r requirements.txt

---

✅ FOLDERS TO KEEP (Currently Used)

Folder	Status	Reason
src/	✅ CRITICAL	Contains all active detector & pipeline code
config/	✅ CRITICAL	Configuration & settings for the app
webapp/	✅ CRITICAL	Flask application with routes, templates, static files
ai_models/	✅ CRITICAL	Actual model files used by detectors
docs/	✅ USEFUL	Documentation (MIGRATION_GUIDE, ARCHITECTURE, etc.)
instance/	✅ AUTO-CREATED	Flask instance folder (db, temp files)
uploads/	✅ RUNTIME	Temp folder for user video uploads
config/	✅ CRITICAL	Application configuration

📋 Cleanup Checklist

PHASE 1: Immediate Cleanup (Safe - No Side Effects)

• Delete NETRA/ directory (contains old detector implementations)
• Delete detection logic/ directory (old pose detector)
• Delete database/models/ directory (empty)
• Delete tests/ directory (empty)
• Delete test_migration.py file (one-time script)
• Delete .sixth/ directory (build artifacts)

Estimated Cleanup: 5 minutes | ~50-100 MB freed

PHASE 2: Conditional Cleanup (Verify First)

• Delete models/ directory AFTER verifying config/ doesn't reference it
  • Check config/model_config.py and config/settings.py
  • Confirm all model paths point to ai_models/

Estimated Cleanup: 2 minutes | ~50-100 MB freed

PHASE 3: Local Machine Cleanup (If Keeping Project)

• Delete venv/ directory (can be recreated)
• Run pip install -r requirements.txt in fresh venv

Estimated Cleanup: 5 minutes | ~200 MB freed

🔍 How I Identified Unused Files

1. Import Analysis: Traced all imports in webapp/app.py

   • Active: from src import ...
   • Unused: from NETRA import ... (ZERO occurrences in running code)

2. Code References: Searched entire codebase for references

   • Found NETRA imports ONLY in:
     • Documentation files (MIGRATION_GUIDE.md)
     • Not in any active Python code

3. Directory Inventory: Listed all folders and cross-referenced with active code

4. Config Verification: Checked config/model_config.py for path references

   • All paths point to ai_models/, not models/

🚀 Recommended Action Plan

Step 1: Backup

# Create a backup before deletion
git add .
git commit -m "Backup before cleanup"

Step 2: Delete in This Order

# Remove old detector implementations
rmdir NETRA

# Remove old detection logic folder
rmdir "detection logic"

# Remove empty directories
rmdir database/models
rmdir tests

# Remove one-time migration script
del test_migration.py

# Remove build artifacts
rmdir .sixth

Step 3: Verify Still Works

python webapp/app.py
# Should start without errors

Step 4: Commit Changes

git add .
git commit -m "cleanup: Remove unused old code from pre-refactoring"
git push

---

⚠️ Important Notes

1. models/ Directory: Before deleting, verify one more time:

   # Check config/model_config.py
   # Search for any reference to 'models/' path
   

2. Documentation References: After cleanup, update docs if they still reference NETRA/:

   • docs/MIGRATION_GUIDE.md - References old NETRA/ structure (can stay as historical record)
   • docs/PROJECT_STRUCTURE.md - References old structure (consider updating)

3. Git History: Even after deletion, history remains in .git/ for recovery

4. Version Control: Make sure .gitignore is up to date after cleanup

✨ Next Steps

1. Run the cleanup steps above
2. Test the application: python webapp/app.py
3. Verify camera feed still works: Navigate to http://localhost:5000
4. Confirm all models load successfully
5. Commit changes to git
