a57718e1ac ICV2017u3 package update;
- Optimizations set change. Now IPP integrations will provide code for SSE42, AVX2 and AVX512 (SKX) CPUs only. For HW below SSE42 IPP code is disabled.
- Performance regressions fixes for IPP code paths;
- cv::boxFilter integration improvement;
- cv::filter2D integration improvement;

[GSOC] Speeding-up AKAZE, part #2 (#8951)

* feature2d: instrument more functions used in AKAZE

* rework Compute_Determinant_Hessian_Response

* this takes 84% of time of Feature_Detection
* run everything in parallel
* compute Scharr kernels just once
* compute sigma more efficiently
* allocate all matrices in evolution without zeroing

* features2d: add one bigger image to tests

* now test have images: 600x768, 900x600 and 1385x700 to cover different resolutions

* explicitly zero Lx and Ly

* add Lflow and Lstep to evolution as in original AKAZE code

* reworked computing keypoints orientation

integrated faster function from https://github.com/h2suzuki/fast_akaze

* use standard fastAtan2 instead of getAngle

* compute keypoints orientation in parallel

* fix visual studio warnings

* replace some wrapped functions with direct calls to OpenCV functions

* improved readability for people familiar with opencv
* do not same image twice in base level

* rework diffusity stencil

* use one pass stencil for diffusity from https://github.com/h2suzuki/fast_akaze
* improve locality in Create_Scale_Space

* always compute determinat od hessian and spacial derivatives

* this needs to be computed always as we need derivatives while computing descriptors
* fixed tests of AKAZE with KAZE descriptors which have been affected by this

Currently it computes all first and second order derivatives together and the determiant of the hessian. For descriptors it would be enough to compute just first order derivates, but it is not probably worth it optimize for scenario where descriptors and keypoints are computed separately, since it is already very inefficient. When computing keypoint and descriptors together it is faster to do it the current way (preserves locality).

* parallelize non linear diffusion computation

* do multiplication right in the nlp diffusity kernel

* rework kfactor computation

* get rid of sharing buffers when creating scale space pyramid, the performace impact is neglegible

* features2d: initialize TBB scheduler in perf tests

* ensures more stable output
* more reasonable profiles, since the first call of parallel_for_ is not getting big performace hit

* compute_kfactor: interleave finding of maximum and computing distance

* no need to go twice through the data

* start to use UMats in AKAZE to leverage OpenCl in the future

* fixed bug that prevented computing determinant for scale pyramid of size 1 (just the base image)
* all descriptors now support writing to uninitialized memory
* use InputArray and OutputArray for input image and descriptors, allows to make use UMAt that user passes to us

* enable use of all existing ocl paths in AKAZE

* all parts that uses ocl-enabled functions should use ocl by now

* imgproc: fix dispatching of IPP version when OCL is disabled

* when OCL is disabled IPP version should be always prefered (even when the dst is UMat)

* get rid of copy in DeterminantHessian response

* this slows CPU version considerably
* do no run in parallel when running with OCL

* store derivations as UMat in pyramid

* enables OCL path computing of determint hessian
* will allow to compute descriptors on GPU in the future

* port diffusivity to OCL

* diffusivity itself is not a blocker, but this saves us downloading and uploading derivations

* implement kernel for nonlinear scalar diffusion step

* download the pyramid from GPU just once

we don't want to downlaod matrices ad hoc from gpu when the function in AKAZE needs it. There is a HUGE mapping overhead and without shared memory support a LOT of unnecessary transfers.

This maps/downloads matrices just once.

* fix bug with uninitialized values in non linear diffusion

* this was causing spurious segfaults in stitching tests due to propagation of NaNs
* added new test, which checks for NaNs (added new debug asserts for NaNs)
* valgrind now says everything is ok

* add nonlinear diffusion step OCL implementation

* Lt in pyramid changed to UMat, it will be downlaoded from GPU along with Lx, Ly
* fix bug in pm_g2 kernel. OpenCV mangles dimensions passed to OpenCL, so we need to check for boundaries in each OCL kernel.

* port computing of determinant to OCL

* computing of determinant is not a blocker, but with this change we don't need to download all spatial derivatives to CPU, we only download determinant
* make Ldet in the pyramid UMat, download it from CPU together with the other parts of the pyramid
* add profiling macros

* fix visual studio warning

* instrument non_linear_diffusion

* remove changes I have made to TEvolution

* TEvolution is used only in KAZE now

* Revert "features2d: initialize TBB scheduler in perf tests"

This reverts commit ba81e2a711.

8b3d6603d5 another round of dnn optimization (#9011)
* another round of dnn optimization:
* increased malloc alignment across OpenCV from 16 to 64 bytes to make it AVX2 and even AVX-512 friendly
* improved SIMD optimization of pooling layer, optimized average pooling
* cleaned up convolution layer implementation
* made activation layer "attacheable" to all other layers, including fully connected and addition layer.
* fixed bug in the fusion algorithm: "LayerData::consumers" should not be cleared, because it desctibes the topology.
* greatly optimized permutation layer, which improved SSD performance
* parallelized element-wise binary/ternary/... ops (sum, prod, max)

* also, added missing copyrights to many of the layer implementation files

* temporarily disabled (again) the check for intermediate blobs consistency; fixed warnings from various builders

3fbe1f8d64 Fix multichannel warping with BORDER_CONSTANT
Warping a matrix with more than 4 channels using BORDER_CONSTANT and
INTER_NEAREST, INTER_CUBIC or INTER_LANCZOS4 interpolation led to
undefined behaviour. This commit changes the behavior of these methods
to be similar to that of INTER_LINEAR. Changed the scope of some of the
variables to more local. Modified some tests to be able to detect the
error described.

4c7aa8645a ocl: validate arguments in KernelArgs constructor
- don't use undefined flag=0. It should be CONSTANT instead.
- don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags).
  This case is not handled well to provide NULL __global pointers.
  It is better to use '-D' macro defines instead (at least for performance)
