Hello friends. The following program WORKED to read image files, but it stopped working and gave the following error: global loadsave.cpp:268 cv::findDecoder imread_ (''): can't open/read file: check file path/integrity …
other “warp” functions in opencv will implicitly invert the given transform, e.g. an affine or homography matrix, such that the result is the expected forward transform. you might have to fit a transformer for the opposite transform, i.e. swap source and destination points.
I think there was an update to the input sent to opencv in version 4.11 and it especially affects Linux-based systems. The question is, how should we adjust the array inputs created with numpy in Linux-based systems in the current version?
Hello guys. I’m during 3 days trying to make opencv to work with CUDA. I already have CUDA installed, cudnn etc. What happens: After making all process described in some youtube videos, many and many times, with lots of versions of opencv, with visual studio 2019 and 2022, the last command which I should do is cmake --build “path” --target INSTALL --config Release. In the example video ...
I tried to run opencv using Visual Studio on Windows 11. But it is missing many include files. I think I was missing some steps during the installation process. For instance if I go look for opencv2/include there is only one include file located in the directory. that file has the name, opencv.hpp the location of that file is placed under the C ...
OpenCV 5 is many years late. Here is a quote from one of their old announcements: “In 2020, OpenCV 5.0 is coming out with an emphasis on deep learning and better performance on lower-power computing platforms. The other OpenCV 5.0 highlights are: Julia and Swift bindings, new 3D vision algorithms with elements of SLAM” scien June 18, 2025 ...
I am building an OpenCV library by Cmake with Cuda. My GPU and Cuda Toolkit are GTX1650 and v12.8, respectively. The command is following: cmake -G "Visual Studio 17 2022" -DCMAKE_BUILD_TYPE=Release ^ -D …
the opencv.js project was a GSoC project, a kind of feasibility study. there is hardly any code using it for LLMs to learn from. approxPolyDP was never useful for things with rounded corners. there’s a new approxPolyN function that you should take a look at. for things with rounded corners, it makes sense.
Hello, I am trying to compile opencv-4.10.0 from source but I am running into a sudden failure during compilation. Below is at the point where make suddenly fails: [ 66%] Built target opencv_text [ 67%] Building CXX ob…
