如何识别/检查模糊图像？ [英] How to identify/check blur image?

问题描述

我们如何识别给定图像模糊或C＃中模糊的百分比？有没有可用的API？或者任何有用的算法？

How can we identify that a given image is blur or how much percent is it blur in C#? Is there any API available for that? Or any algorithm that can be helpful in that?

谢谢！

推荐答案

虽然，我在提问8到9年后发布了这个答案。那时，我通过在图像上应用模糊然后与原始图像进行比较来解决这个问题。

Although, I am posting this answer after 8-9 years after asking the question. At that time, I resolved this problem by applying blur on image and then comparing with the original one.

当我们在非模糊图像上应用模糊时，我的想法是然后比较它们，图像的差异非常大。但是当我们在模糊图像上应用模糊时，图像的差异几乎是10％。
通过这种方式，我们解决了识别模糊图像的问题，结果非常好。

The idea is, when we apply blur on a non-blurry image and then compare them, the difference in images is very high. But when we apply blur on a blurry image, the difference in images is almost 10%. In this way, we resolved our problem of identifying blur images and the results were quite good.
