* Anna:
* Done:
* Andrey: Moved cv2 binary from the root directory in OpenCV python package to the proper folder, the same as it locates in the original OpenCV build.
* Andrey: The idea to keep extra imports for OpenCV python package in opencv repository is not very good, kept them in opencv-python repository and adapted to the changes.
* Andrey: Replaced distutils module in opencv repository because deprecation warnings happen.
* Alexander P: cv2.remap in the cv2.INTER_LINEAR has some problem in border values, issue #21148
there is no problem in INTER_LINEAR, INTER_CUBIC, ..., interpolations. The problem is in the matrix mapping. The code fixing mapping was attached. issue was closed
* Egor: Add ArgMax and ArgMin layers #21208 PR merged
* Egor: Merged every fix to master locally to check ONNX score - 24.11%(it was 19.35%)
* Egor: PRs merged:
* fix ceil_mode for Average/MaxPooling PR
* Add alpha parameter to ELU layer PR
* Add Log/Softmax simplification PR
* Add default order to Transpose PR
* add Sum of 1 input PR
* In progress:
* Andrey: Testing python limited API for OpenCV python package, which may reduce the opencv-python package size.
* Andrey: Implementing downloading models function in a python package.
* Alexander P: some samples from ArUco tutorial are not reproduced. prepared PR Update ArUco tutorial #3126; added new tests for tutorial; fixed flags and samples; added calibrate photos; added new custom dictionaries; refactoring samples of ArUco (-500 lines of code).
* Egor: Implemented acos, acosh, asin, asinh, atan, atanh, cos, cosh, erf, hardswish, sin, sinh, softplus, softsign, tan layers #21176
* Egor: Implemented celu, hardsigmoid, selu, thresholdedrelu layers #21190
* Egor: WIP on general broadcasting layer
* Alexander:
* The fix for PnPRansac with USAC parameters has been prepared: https://github.com/opencv/opencv/pull/21166
Aleksandr Alekhin provided some comments, they will be addressed by the author.
* DNN speech recognition sample PR is opened: https://github.com/opencv/opencv/pull/21197
* In this PR Audio I/O functionality has been integrated into python sample (instead of using Python audio library SoundFile). C++ sample is gong to be updated as well.
* Filtering has been proposed for ONNX conformance tests suite: https://github.com/opencv/opencv/pull/21088
* SO version will be increased each release to maintain ABI compatibility: https://github.com/opencv/opencv/pull/21178
* Bit-exact tests for YUV cvtColor conversions have been implemented: https://github.com/opencv/opencv/pull/21193
