PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to calculate intersection over union.
  2. Apply IoU and Object detection to compute the required result.
  3. Display the result for calculate intersection over union and compare it with the documented sample output.

This example of calculate intersection over union computes the result directly from the prepared sample data. It demonstrates IoU and Object detection and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For calculate intersection over union, keep the data shape and value types consistent with IoU.

Check this

Apply IoU in the same order shown by the algorithm; changing the order can change the result.

Check this

Check denominators, numeric ranges and rounding before comparing the calculated value.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
