OpenCV: cv::ximgproc::GuidedFilter Class Reference

WebThe code also includes the fastest edge keep filters; bilateral filter [URL] joint bilateral filter [URL] trilateral filter [URL] guided filter [URL] For example, the bilateral filter is about 10x faster than the OpenCV function, and guided filter is 20x faster than the Matlab function. The codes are tested on Visual Studio 2010. WebIn this section, the procedure to run the C++ code using OpenCV library is shown. Here, “Hello OpenCV” is printed on the screen. Aim is to validate the OpenCV installation and usage therefore the opencv.hpp is included in the code but not used in this example. First create the “Hello OpenCV” code as below, 1 2 3 4 5 6 7 8 9 10 WebHere is my execution: cvtColor (src,src_grey,CV_BGR2GRAY); Mat dst = myfilter2d (src_grey,filter); imshow ("myfilter2d",dst); filter2D (src_grey,dst2,-1,filter); imshow … solved clue about unknown
