Sep 02, 2016 · With OpenCV, stitching images to make a panorama is very easy. I will go over how to create a beautiful panorama image using OpenCV 3.1.0. Because there is a bug in OpenCV 3.1.0 Stitcher class when OpenCL is enabled, we will need to turn it off when building.
You did not include opencv4 and pthread libraries while compiling. You can use the makefile in my previous post. Copy it into a file Makefile.Then rename your filename to srv.cpp.
These images below are a few examples of the editing that were made to the original picture: blue, blurred, cartoonized, exposured, mixed colors, old photo, overlay, portion of image, rotated, sharpened, sunburst, textured. Look for image similarities if they're not equal
Mar 17, 2016 · However, I want to keep using opencv 2.4.x because in opencv 3 module “legacy” is removed, and it contains the functions calculating GLCM (texture.cpp) used in my project. The problem appears when I port my app from windows to android, OpenCV4Android does not have those functions either so I must build opencv libs for android from source.
Is there a way to eliminate the upload/download steps to convert a cv::Mat object to a cv::cuda::GpuMat object on the Nano since the GPU and CPU can both access the same memory? I’m looking for a solution to take advantage of the OpenCV cuda functionality, but avoid the penalty of copying from Mat to GpuMat and back again. // cpu_img has data but requires processing best done on a gpu. cv ...
I've been using OpenCV for a while now and the cv::Mat confused me too, so I did some reading. cv::Mat is a header that points to a *data pointer which holds the actual image data. It also implements reference counting. it holds the number of cv::Mat headers currently pointing to that *data pointer. So when you do a regular copy such as:
