Alexander Smorkalov 84d391aac4 Added heuristic to allocate buffer for FAST features depending on input image resolution. 2025-08-12 11:07:35 +03:00
Haosonn 75d9ac3964 Merge pull request #27391 from Haosonn:pr-rvv-hal-fast 
hal/riscv-rvv: implement FAST keypoint detection #27391

An implementation of FAST keypoint detection with NMS/noNMS version.

A new perf test is written, and the perf test is evaluated in two platforms: K1/K230.
Accelaration is achieved when threshold is high, however, weird stat shows that the acceleration doesn't work when threshold is low (the number of keypoint candidates is high).

OpenCL subsystem is initialized:
- haveOpenCL() is called from application
- useOpenCL() is called from application
- access to OpenCL allocator: UMat is created (empty UMat is ignored) or UMat <-> Mat conversions are called

Don't call OpenCL functions if OPENCV_OPENCL_RUNTIME=disabled
