  cvtest::norm(out_mat(roi), out_mat_ocv(roi), NORM_INF)
    Which is: 2

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues,
  answers.opencv.org, Stack Overflow, etc and have not found solution
• I updated to latest OpenCV version and the issue is still there
• There is reproducer code and related data files: videos, images, onnx, etc

@asmorkalov there were some changes in the Resize algorithm since then, could please recheck if the issue is still applicable? (We don't have any ARM machines right now)

[asmorkalov]

@asenyaev Please try to remove the tests from ARM64 test filter and run tests.

Hello @dmatveev! I tried to turn on gapi tests on ARM64 machines (Linux and macOS) and there are still issues. You can check additional information of certain tests in logs for all configurations:

• OCV Contrib 4.x Linux ARM64
• OCV Contrib 4.x macOS ARM64
• OCV Contrib 5.x Linux ARM64
• OCV Contrib 5.x macOS ARM64
• OCV 4.x Linux ARM64
• OCV 4.x macOS ARM64
• OCV 5.x Linux ARM64
• OCV 5.x macOS ARM64
  Notice: accuracy and performance tests both failed.

Thanks @asenyaev ! We'll look more into it.

@asenyaev Could you please apply #22471 patch and run gapi test on ARM one more time to check that issue is fixed?

Hello @anna-khakimova! I've applied #22471 patch and run OpenCV pipelines on ARM and there are still issues. You can check logs here:

• OCV Contrib 4.x Linux ARM64
• OCV Contrib 4.x macOS ARM64
• OCV 4.x Linux ARM64
• OCV 4.x macOS ARM64
