add smoothing line to results.png to improve readability

[PetervanLunteren]

EDIT: this is the third PR for this, but now I'm signing off with my real email address in stead of an pseudo one. Signing the CLA should be OK now.

This PR contains a very small addition to the original code (+ 2 lines) and does not interfere with the machine learning process whatsoever. It adds a smoothing line on top of the original plots in the results.png. With this smoothing line I hope to improve plot readability for users and provide a better insight into when their model has the best fit, and where their model is under- or overfitted.

Summary

📈🔬🎨

This pull request enhances the plot_results function in utils/plots.py by applying a Gaussian filter to smooth the plot lines. This makes the results easier to visualize and compare.

To make the plot results more clear
We added a feature to smooth and smear
Using gaussian_filter1d
We reduced the noise indeed
And now the trends are easier to peer

Walkthrough

• Import and apply gaussian_filter1d function to smooth plot lines in plot_results (link, link)

🛠️ PR Summary

🌟 Summary

Enhanced results plotting in YOLOv5 with smoothing functionality.

📊 Key Changes

• Integrated gaussian_filter1d from scipy for data smoothing.
• Added a smoothed line to the plots using the Gaussian filter alongside actual results.

🎯 Purpose & Impact

• 🎨 Visual Improvement: The smoothing line helps in identifying trends more clearly by reducing noise in the plotted results.
• 📈 Better Analysis: Users can better interpret model performance over time, particularly useful during training and evaluation.
• 🔬 Greater Insight: Smoother visual transitions between data points can reveal underlying patterns that might be obscured by raw results.

I'm having trouble signing the CLA. I believe that I should receive instructions how to sign via email? Would it be possible to check whats going wrong with the CLA-bot? Thanks!

[glenn-jocher]

@PetervanLunteren hello there! I'm sorry to hear that you're having trouble signing the CLA. The CLA bot usually sends an email with instructions on how to sign after you open the pull request. If you haven't received an email, it's possible that it was filtered out or went to your spam folder. Here are a few things you can try:

1. Check your spam folder for the CLA email, in case it was mislabelled
2. Log in to the GitHub account that you used to create the pull request, and verify that the email address associated with your account is correct and active
3. Re-open the pull request, in case there was an error in the initial process

If these solutions don't work, please let us know and we will do our best to help you resolve the issue. Thank you for your interest in contributing to YOLOv5!

Hi Glen, Thanks for your reply.

1. There is nothing in my spam folder
2. I've verified the email address which made the PR and it is correct
3. I've reopened the PR and still there is no email

Would it be possible to send the email manually? My email address is contact@pvanlunteren.com

Hello @PetervanLunteren, I'm sorry to hear that you still haven't received the email to sign the CLA. Unfortunately, we are not able to manually send the email as it is an automated process handled by the CLA bot.

One reason for not receiving the CLA bot email could be if the email address that you have registered with GitHub is not associated with the email you're checking. Another possible reason could be delays in the delivery of emails.

To ensure that you receive the CLA email, please make sure that the registered email address on your GitHub account is correct and active, and that it matches the email address that you are checking. You could also try waiting for a few more hours in case there are any delays in delivery.

Thank you for your interest in contributing to YOLOv5. Please let us know if you have any more questions or if there is anything else we can help with.

Hi Glenn, Thanks for your message. I've checked the email address that I have registered with GitHub and it is correct, active and set to be "Visible in emails". The PR is signed off with my email address, not an @users.noreply.github.com account.

I also don't think the issue is a delay in email delivery, as this PR has been created last week.

@AyushExel PR here to update plots. What do you think?

[AyushExel]

Looks great!

[glenn-jocher]

@PetervanLunteren merging PR! Do you think you could do the same update for YOLOv3 at https://github.com/ultralytics/yolov3 and YOLOv8 at https://github.com/ultralytics/ultralytics? I'd really appreciate it to keep everything consistent 🙏

[PetervanLunteren]

@glenn-jocher Will do! Thanks
