Optimization of image resizing (method Nearest) with using SIMD
I know that 'Nearest' method of image resizing is the fastest method.
Nevertheless I search way to speed up it.
Evident step is a precalculate indices:
void CalcIndex(int sizeS, int sizeD, int colors, int* idx)
{
float scale = (float)sizeS /…

AVX-512BW emulation of _mm512_dpbusd_epi32 AVX-512VNNI instruction
There are AVX-512 VNNI instructions starting since Cascade Lake Intel CPU which can accelerate inference of quantized neural networks on CPU.
In particular there is a instuction _mm512_dpbusd_epi32 (vpdpbusd) which allows to perform multiplication…

NEON emulation of VNNI instructions
There is new AVX-512 VNNI instructions in Cascade Lake Intel CPU which can accelerate inference of neural networks on CPU.
I integrated them into Simd Library to accelerate Synet (my small framework for inference of neural networks) and obtained…

Detection of small fast objects with using of Simd::Motion::Detector
I try to use motion detector to detect shooting star in the video with the example of code UseMotionDetector.cpp.
If I use the motion detector with default options than nothing works.
I think that may be connected with small object size, its fast…
