Yuantao Feng 3f13ce797b Merge pull request #25779 from fengyuentau:dnn/fix_onnx_depthtospace ... dnn: add DepthToSpace and SpaceToDepth #25779 We are working on updating WeChat QRCode module. One of the new models is a fully convolutional model and hence it should be able to run with different input shapes. However, it has an operator `DepthToSpace`, which is parsed as a subgraph of `Reshape -> Permute -> Reshape` with a fixed shape getting during parsing. The subgraph itself is not a problem, but the true problem is the subgraph with a fixed input and output shape regardless input changes. This does not allow the model to run with different input shapes. Solution is to add a dedicated layer for DepthtoSpace and SpaceToDepth. Backend support: - [x] CPU - [x] CUDA - [x] OpenCL - [x] OpenVINO - [x] CANN - [x] TIMVX - ~Vulkan~ (missing fundamental tools, like permutation and reshape) ### 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		8 months ago
