opencv - MedianBlur() calculate max kernel size - Stack Overflow
Web20 de jun. de 2013 · The OpenCV documentation seems to be very clear: src – input 1-, 3-, or 4-channel image; when ksize is 3 or 5, the image depth should be CV_8U, CV_16U, or CV_32F, for larger aperture sizes, it can only be CV_8U. As you need to cater for signed values, I think your best option is to use CV_32F. Also, the documentation says. Web3 de mai. de 2024 · (I use opencv4nodejs, but I also tried the original OpenCV 3.4.6). I did reduce the ksize in a try/catch loop, but not so effective, since I have to work with videos. I did checkout the OpenCV source code and did some research. In OpenCV 3.4.6, the crash come from line 241, file opencv\modules\imgproc\src\median_blur.simd.hpp: tsaxana reserve
