🎲 Rubik's Cube Image Analysis Results

📊 Image Information:
- Size: {width} x {height} pixels
- Format: {image.format if hasattr(image, 'format') else 'PIL Image'}

🔍 Detection Status:
✅ Image uploaded successfully
✅ Image format is correct
⚠️  Complete AI model is still in training

📝 Note:
This is a demo version of the Rubik's cube recognition system.
The complete RetinaNet model needs to be trained before accurate cube detection can be performed.

🚀 Feature Preview:
- Cube face detection
- Color tile recognition (Red, White, Blue, Orange, Green, Yellow)
- 3D position analysis
- Cube state evaluation
