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/ikkjin/getImgGrad.m | 7 +++++++ 1 file changed, 7 insertions(+) create mode 100755 SD-VBS/common/toolbox/ikkjin/getImgGrad.m (limited to 'SD-VBS/common/toolbox/ikkjin/getImgGrad.m') diff --git a/SD-VBS/common/toolbox/ikkjin/getImgGrad.m b/SD-VBS/common/toolbox/ikkjin/getImgGrad.m new file mode 100755 index 0000000..90fae28 --- /dev/null +++ b/SD-VBS/common/toolbox/ikkjin/getImgGrad.m @@ -0,0 +1,7 @@ +function Ig=getImgGrad(imgroi) +im = double(rgb2gray(imgroi)); +g1 = fspecial('gaussian', 9,1); % Gaussian with sigma_d +img1 = conv2(im,g1,'same'); % blur image with sigma_d +Ix = conv2(img1,[-1 0 1],'same'); % take x derivative +Iy = conv2(img1,[-1;0;1],'same'); % take y derivative +Ig=Ix.^2+Iy.^2; \ No newline at end of file -- cgit v1.2.2
