Tomoaki Teshima	3c2f7ecc97	speed up accumulate, accumulateSquare, accumulateProduct and accumulateWeighted using SIMD * use SSE and/or AVX based on configuration * revise the test to verify the implementation	8 years ago

Gilles Rochefort	9e53f03968	Fixed BackgroundSubstractorMOG2 in opencv_video. The number of gaussians involved in a mixture is supposed to be dynamically adjusted. After being increased, the number of gaussians can't be reduced anymore. It seems to be a regression as the legacy code located in modules/legacy/src/bgfg_gaussmix.cpp allows to reduce such number of gaussians.	9 years ago

Owen Healy	86fb9f8409	Modify findTransformECC to support a mask of pixels to consider Tests of the mask are also included. This is useful for registering a non-square image against a non-square template. This also needs to relax a sanity check as per https://github.com/Itseez/opencv/pull/3851	10 years ago
Owen Healy	ff48387a8a	Fix bug of uninitialized matrix in findTransformECC The matrix templateZM needs to be initialized because otherwise uninitialized values leak into the correlation in: const double correlation = templateZM.dot(imageWarped) In the worst case this will lead the correlation to be NaN ruining the whole routine. The subtraction does not initialize templateZM due to the mask. Unfortunately, the uninitialized values (by altering the correlation) have the side effect of dragging out the computation a little longer giving a slightly better error bound. This means that fixing this bug breaks perf_ecc where SANITY_CHECK(warpMat, 1e-3); is just a little too tight and happens to work due to the uninitialized values. Since this is a performance not a accuracy test I think it is OK to just relax the error bound a little bit (the tight error bound being after all the result of a bug).	10 years ago

Daniel Angelov	303868b3c4	Fixed variable name consistency The function parameters were different from the ones described below. P.S. Why is ``flow`` InputOutputArray, shouldn't it be just OutputArray? If so, shouldn't the reason be specified - e.g. so others can benefit as well (e.g. not allocating memory on every frame?)	10 years ago
