本文介绍了如何在OpenCV中锐化图像?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 如何使用 OpenCV 锐化图像?有许多平滑或模糊的方法,但没有我能看到的锐化。How to sharpen an image using OpenCV? There are many ways of smoothing or blurring but none that I could see of sharpening.推荐答案一个通用程序在关于反锐化掩蔽的维基百科文章:您使用高斯平滑滤波器并减去来自原始图像的平滑版本(以加权方式使得常量区域的值保持不变)。One general procedure is laid out in the wikipedia article on unsharp masking:You use a gaussian smoothing filter and subtract the smoothed version from the original image (in a weighted way so the values of a constant area remain constant).获得框架的锐化版本进入图像 :(两个 cv :: Mat )cv::GaussianBlur(frame, image, cv::Size(0, 0), 3);cv::addWeighted(frame, 1.5, image, -0.5, 0, image);您需要为自己调整参数。 The parameters there are something you need to adjust for yourself. 还有laplacian锐化,你应该在google上找到一些东西。There's also laplacian sharpening, you should find something on that when you google. 这篇关于如何在OpenCV中锐化图像?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
