Thanks! ""OpenCV can use OpenVINO backend" means that OpenVINO has some OpenCV compatibility, so it can take OpenCV Mat

2019-06-22 17:14:53 -0500 marked best answer Can I use NCS2 (VPU Myriad X) for acceleration cv::StereoBM?

Can I use NCS2 – Neural Compute Stick 2 (Myriad™ X) for acceleration cv::StereoBM and cv::StereoSGBM OpenCV functions in the last OpenCV 4.x versions?

Should I use custom OpenCV(OpenVINO) version? https://www.learnopencv.com/using-ope...

Note that OpenVINO ships with it’s own OpenCV version.

As known, OpenCV supports OpenVINO that uses Neural Compute Stick 2 (Myriad™ X): https://opencv.org/opencv-4-0-0.html

dnn module was updated with Deep Learning Deployment Toolkit from the OpenVINO™ toolkit R4

But can NCS2 be used for cv::StereoBM / cv::StereoSGBM instead of Deep Neural Networks?

But how can I construct the corresponding rotation matrix from Euler angles?

2016-02-25 03:05:56 -0500 asked a question How can I get rotation-vector from Euler-angles?

If I have 3 Euler-angles then how can I get rotation-vector to use it for camera-rotation in OpenCV-viz3d?

I.e. how can I get Vec3d( X, Y, Z) from Euler-angles (alfa, betta, gamma) to use in this code?

viz::Viz3d viz_3d_window("Viz window");
cv::Affine3d pose = viz_3d_window.getViewerPose();
viz_3d_window.setViewerPose( pose.rotate( Vec3d( X, Y, Z) ) );

cv::Affine3d::rotate(); https://github.com/Itseez/opencv/blob...

I can find Euler-angles from rotation-matrix by using RQDecomp3x3() or as shown in that question, but whether is there an inverse function in the OpenCV to find rotation-matrix from Euler-angles or better to find rotation-vector( Vec3d( X, Y, Z) )?

How can I get 3x4 projection matricies of the first and the second cameras to use triangulatePoints() if I have only struct detail::CameraParams for each of two cameras which I got from detail::Estimator?

@break Can this file (cow.xml) be used for the LatentSVMDetector (opencv2.4) instead of DPMDetector (opencv3.0)?

2015-10-14 23:33:34 -0500 asked a question Is there anywhere XML-files already trained to detection most popular objects?

I found ready treained XML-files only for face and its details (haarcascades), and for human body (HOG): https://github.com/Itseez/opencv/tree...

Is there anywhere a (database) link to XML-files already trained to detection of different objects: cars, planes, people, animals, plants and other most popular objects?

I'm interested in the XML-files for both types: HOG and CascadeClassifier (haarcascades)
