Extended support for Resize and Split layers #29323 Merge with: https://github.com/opencv/opencv_extra/pull/1379 Key changes: Resize layer: _antialias_ (linear & cubic) :- PIL-style separable resampling with stretched filter support and edge-clamped, renormalized weights. _axes_ (incl. reversed [3,2]) :- getOutShape, the scale override, and runtime _tf_crop_and_resize_ ROI parsing now map 2-element sizes/scales/roi by the axes order instead of assuming [2,3]. _keep_aspect_ratio_policy_ (not_larger/not_smaller) :- output size from min/max per-axis scale. _half_pixel_symmetric_ :- new coordinate-transform mode + importer mapping. _align_corners_ downsampling :- coordinate scale uses the unfloored scaled length (in−1)/(in·x_scale−1). Split Layer: _convertTo empty 1-D Mat:_ the empty-Mat branch collapsed a 1-D [0] to 2-D [1,0] via cv::Size(); now uses allowTransposed like the non-empty path. ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake
