Checklist

Essentials

Please feel free to remove inapplicable items for your PR.

  • The PR title starts with [MXNET-$JIRA_ID], where $JIRA_ID refers to the relevant JIRA issue created (except PRs with tiny changes)
  • Changes are complete (i.e. I finished coding on this PR)
  • All changes have test coverage:
  • Unit tests are added for small changes to verify correctness (e.g. adding a new operator)
  • Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore)
  • Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL)
  • Code is well-documented:
  • For user-facing API changes, API doc string has been updated.
  • For new C++ functions in header files, their functionalities and arguments are documented.
  • For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable
  • Check the API doc at http://mxnet-ci-doc.s3-accelerate.dualstack.amazonaws.com/PR-$PR_ID/$BUILD_ID/index.html
  • To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change

The tests added don't really verify the action that has been taken. Would it be possible to add a really simple script that reads the image and asserts that the requested rectangle exists? A simple iterator that goes along the edges of the rectangle and verifies the colour should be sufficient

@marcoabreu add some pointwise checking on the bounding box in Scala. So the test will check the color of the four corners to make sure if they have the same color.

The recent commit cancelled the check on top-left corn because of overlapping text

Can we also clean up the file we created in the unit test here ?

Since it is created under the temp folder, system will clean it up in a certain period

Find a Java bug during adding this into Object Detector. This commit include that fix

Tested and it works with the Clojure package through interop 😸

out

I'll open an issue for the Clojure package to pick up the new feature in the core package.
