Vadim Pisarevsky	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	8 years ago

mschoeneck	4a4d94f266	Merge pull request #8694 from mschoeneck:Canny Parallelize Canny with custom gradient (#8694) * New Canny implementation. Restructuring code in parallelCanny class. Align mag buffer and map. * Fix warnings. * Missing SIMD check added. * Replaced local trailingZeros in contours.cpp. Use alignSize in canny.cpp * Fix warnings in alignSize and allocate just minimum extra columns. * Fix another warning in map.create. * Exchange for loop by do loop to avoid double check at the beginning. Define extra SIMD CANNY_CHECK to avoid unnecessary continue.	8 years ago

Artem Lukoyanov	c4ae5c0ee5	Added assertios to remap and warpAffine functions Remap and warpAffine functions do not support more than 4 channels in Bicubic and Lanczos4 interpolation modes. Assertions were added. resolve #8272	8 years ago
vartenkov	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.	8 years ago
