Detect traffic signs using MATLAB

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

Process the `dashboard_cam_footage_001.mp4` video to detect all stop signs using the pre-trained `trafficSignDetector` model and save the frames with detected signs to the `detected_signs` folder.

Before I send this analysis to the autonomous vehicle team, process `highway_test_run_footage.mp4` to detect all traffic signs. For each sign detected, highlight not only the sign itself but also display the confidence score of the detection and the estimated distance to the sign, so they can quickly assess the model's performance in real-world conditions.

I'm trying to detect traffic signs in new test footage, but the model is missing signs in poor lighting and generating false positives.
I'm running `urban_drive_footage_night.mp4` through our sign detection model for the safety review meeting tomorrow, and it's failing to pick up several yield signs in shadows, while also falsely identifying some billboards as stop signs. The project lead will want to know why our model isn't robust in varied conditions. How do I quickly identify the specific failure modes (lighting vs. sign type) and what's the most effective immediate adjustment I can make to improve detection accuracy for this specific video?

I keep struggling with the reliability of our traffic sign detection models under diverse real-world conditions.
I frequently find our traffic sign detection models underperforming when presented with new footage that has varying lighting, weather, or sign degradation. It's a constant battle of tweaking parameters or retraining for specific edge cases, which is inefficient and delays our development. What habit should I change in how I approach evaluating and improving these detection models to build more robust and generalizable solutions from the outset?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
