WebJan 8, 2013 · cv::cuda::mulAndScaleSpectrums (InputArray src1, InputArray src2, OutputArray dst, int flags, float scale, bool conjB=false, Stream &stream=Stream::Null()) Performs a per-element multiplication of two Fourier spectrums and scales the result. WebApr 29, 2008 · I have one kernel where I get a tiny performance improvement by using bitwise & instead of &&. The parentheses can’t hurt :) And they certainly make the code more readable. Check a C reference book on the priority of the & and < operators to know for sure. Yes, && do short circuit. Lastly, I will add that in CUDA you often have to try both.

WebMar 30, 2015 · Modern GPUs have sinle-precision FMA (fused multiply-add) which allows a double-float to be implemented in about 8 instructions. The hard part is the double-float addition. If done accurately, it needs about 20 instructions. Note that double-float provides fewer bits than proper IEEE-754 double precision, also there is no correct rounding.
