[RSDK-9506] explicitly use xMin, yMin, etc. in bounding boxes

[penguinland]

Everything compiles, but I haven't tried running it yet. I'll do that while you take a look at the changes...

(doing this now because Alexis got confused why a ticket assigned to me was in her epic)

Could you create unit tests for 3 cases:

• An empty valid regions attribute
• a correct valid regions attribute
• an incorrect valid regions attribute

You can use the struct directly, you dont have to do the json parsing

[bhaney]

You'll def want to manually test this on a local machine to see if it works as intended

Take another look. I've added a bunch of unit tests, and they all pass. I've also gotten this up and working with a webcam on my desk:

{
  "n_samples": 5,
  "chosen_labels": {
    "person": 0.7
  },
  "valid_regions": {
    "cam": [
      {
        "x_max": 1,
        "y_min": 0.5,
        "y_max": 1,
        "x_min": 0
      }
    ]
  },
  "detector_name": "vision-ml-model",
  "count_thresholds": {
    "none": 0,
    "two": 2,
    "three": 3,
    "one": 1
  },
  "sampling_period_s": 5
}

It reads "none" when I duck into the bottom half of the frame, and "one" when I sit up straight in the top half. I can change the Y range to the full 0-1 and the X range to 0-0.5, and it reads "one" when I'm in the left half and "none" when I'm in the right half. Finally, if I set XMax and XMin both to 0, it reads "one" no matter where in the frame I am (and "none" if I'm out of frame)

LGTM!
