Jojo R	12b8d542b7	norm.cpp(normL2Sqr_): improve performance of pipeline ... The most of target machine use one type cpu unit resource to execute some one type of instruction, e.g. all vx_load API use load/store cpu unit, and v_muladd API use mul/mula cpu unit, we interleave vx_load and v_muladd to improve performance on most targets like RISCV or ARM.	2020-11-19 09:49:49 +08:00

In the cudaarithm module, make sure cuda_runtime.h only gets included when CUDA is installed. In the stitching module, don't assume that cuda is present just because cudaarithm and cudawarping are present (as is the case when building with the above options).	2020-10-21 15:51:46 -07:00

Clement Courbet	da555a2c9b	Optimize opencv dft by vectorizing radix2 and radix3. ... This is useful for non power-of-two sizes when WITH_IPP is not an option. This shows consistent improvement over openCV benchmarks, and we measure even larger improvements on our internal workloads. For example, for 320x480, `32FC*`, we can see a ~5% improvement}, as `320=2^6*5` and `480=2^5*3*5`, so the improved radix3 version is used. `64FC*` is flat as expected, as we do not specialize the functors for `double` in this change. ``` dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, false) 1.239 1.153 1.07 dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, true) 0.991
