Add tutorial: Comparison and practical usage of perception metrics

[roPatel69]

Hi! I would like to propose adding a tutorial to improve the experience for beginners.

Topic

Comparison and practical usage of different perception metrics

What I plan to add

• Clear explanation of metrics such as IoU, Precision, Recall, etc.
• A comparison to highlight the differences between them
• Simple examples demonstrating when each metric is most useful
• (Optional) a small visualization or notebook for better understanding

Why this would be useful

While the documentation explains individual metrics, there isn’t much focus on comparing them.
This can make it difficult for beginners to decide which metric to use in different scenarios.
The proposed tutorial aims to address this gap.

Proposed structure

1. Introduction to perception metrics
2. Explanation of key metrics
3. Comparison (table or summary)
4. Example use cases
5. Conclusion

Please let me know if this aligns with the project goals or if any changes are needed.
