Gauss filter opencv
Webby using ANY blur filter on the camera's output the visual quality improves drastically: The above image was created using OpenCV's cv::medianBlur with a kernel size of 3. I identified cv::medianBlur to be the fastest smooth/blur method in OpenCV. However for my needs it is still too slow since it uses up to 80% of the whole processing time ... WebMar 14, 2024 · Gaussian金字塔是一种常用的图像处理技术,用于在不同尺度上对图像进行分析和处理。它通过对原始图像进行高斯滤波和降采样来生成一系列图像,每个图像比前一个图像小一半,同时保留了图像中的结构和细节信息。
