327f92cc46 Precompute the divisor to ensure that no kind of compiler would process it on the fly at each call. 2020-07-01 18:52:05 +02:00
Pierre-Emmanuel Viel
482cacd420 Mix of 32 and 64bits vector types prevents vectorisation for distance computation. 
Argument "a" is of type ElementType* that is either int* or float*, while b was double*.
Mixing types prevents the possibility to use SSE or AVX instructions.
On implementation without SIMD instructions, this doesn't show any impact on performance.

Merge pull request #17642 from pemmanuelviel:pev--fixes-and-clean 
* Clean: make the use of the indices array length consistent

Either we don't want this method to be used in the future for any other node
than the root node, and so we replace indices_length by size_ and remove it as
argument, or we want to be able to use it potentially for other nodes, and
so using size_ instead of indices_length would have lead to a bug.

* Fix: b was not an address

* Fix: transpose the Flann repo commit "Fixes in accum_dist methods" from Adil Ibragimov

Avoids trying to compute log(ratio) with ratio = 0

* Fix: transpose the Flann repo commit "result_set bugfix" from Jack Rae

* Fix Jack Rae commit as the initial i - 1 index was decremented before entering the loop body

* Clean: transpose the Flann repo commit "Updated comments in lsh_index" from Richard McPherson

* Fix: Transpose the Flann repo commit "Fixing unreachable code in lsh_table.h" from hypevr

* Fix warning the same way it was done in flann standalone repo

* Change the return value in case of unsupported type

06b4292534 Fix: error in the dimension used for computeMinMax 
Instead of using the current dimension for which we just got a big span,
we were computing Min and Max for the previous dimension stored in cutfeat
(and using 0 instead of the dimension indice for the very first dimension
with "span > (1-eps)max_span")

7c72e095fa Fix Flann compilation under nvcc + NEON 
All <arm_neon.h> includes in core/cv_cpu_dispatch.h are protected by an
ifndef __CUDACC__ to prevent attempting to use neon intrinsics when
compiling cuda kernels (.cu) -- this prevents hard errors such as
  error: identifier "__builtin_neon_qi" is undefined

Add this same protection to flann/dist.h to fix compilation involving
flann.hpp.

9f1218b00b Merge pull request #11897 from Jakub-Golinowski:hpx_backend 
* Add HPX backend for OpenCV implementation
Adds hpx backend for cv::parallel_for_() calls respecting the nstripes chunking parameter. C++ code for the backend is added to modules/core/parallel.cpp. Also, the necessary changes to cmake files are introduced.
Backend can operate in 2 versions (selectable by cmake build option WITH_HPX_STARTSTOP): hpx (runtime always on) and hpx_startstop (start and stop the backend for each cv::parallel_for_() call)

* WIP: Conditionally include hpx_main.hpp to tests in core module
Header hpx_main.hpp is included to both core/perf/perf_main.cpp and core/test/test_main.cpp.
The changes to cmake files for linking hpx library to above mentioned test executalbles are proposed but have issues.

* Add coditional iclusion of hpx_main.hpp to cpp cpu modules

* Remove start/stop version of hpx backend
