From d17b33131c14864bd1eae275f49a3f148e21cf29 Mon Sep 17 00:00:00 2001 From: Leo Chan Date: Thu, 22 Oct 2020 01:53:21 -0400 Subject: Squashed commit of the sb-vbs branch. Includes the SD-VBS benchmarks modified to: - Use libextra to loop as realtime jobs - Preallocate memory before starting their main computation - Accept input via stdin instead of via argc Does not include the SD-VBS matlab code. Fixes libextra execution in LITMUS^RT. --- SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc | 32 ++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100755 SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc (limited to 'SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc') diff --git a/SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc b/SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc new file mode 100755 index 0000000..8667ec4 --- /dev/null +++ b/SD-VBS/common/toolbox/lagrcv/calcSobelMex.cc @@ -0,0 +1,32 @@ + +/* compile with +rm liblagrcv.a +gcc -c lagrcv.cpp +ar rc liblagrcv.a lagrcv.o +ranlib liblagrcv.a +mex7 calcTextureMex.cc -L/home/ikkjin/LagrMatlab/opencv/matlab -llagrcv -I/home/ikkjin/LagrMatlab/opencv/matlab/ +*/ + +#include "mex.h" +#include "lagrcv.h" +#include +#include + +// TODO: add number of corners parameter +void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { + // usage: [dx dy] = + // calcSobelMex(image) + + double *image, *dx, *dy; + const int *imdims; + + image=(double*)mxGetPr(prhs[0]); + imdims = mxGetDimensions(prhs[0]); + + plhs[0] = mxCreateNumericMatrix(imdims[0], imdims[1], mxDOUBLE_CLASS, mxREAL); + plhs[1] = mxCreateNumericMatrix(imdims[0], imdims[1], mxDOUBLE_CLASS, mxREAL); + dx=(double*)mxGetPr(plhs[0]); + dy=(double*)mxGetPr(plhs[1]); + + calcSobel(image, imdims[0], imdims[1], dx, dy); +} -- cgit v1.2.2
