Gauss filter opencv
WebЯ знаю, что могу использовать предварительно созданные функции OpenCV для обработки фильтров, но я хотел изучить методологию, лежащую в основе этого, поэтому я создал свои собственные. WebMar 29, 2024 · Left: Median filter. Right: Gaussian filter. You can see the median filter leaves a nice, crisp divide between the red and white regions, whereas the Gaussian is a little more fuzzy.
