拍照片的时候,经常由于对焦失败或者抖动了,导致拍出来的照片会很模糊,大家都遇到过吧?如果不是很重要的照片,也就算了,直接删除了。如果照片非常重要又不可能再回去重新拍一次,怎么办呢?在此强烈推荐一款让图片模糊变清晰的软件:SmartDeblur。它内置独特的算法,可以轻松修复这些照片,让图片“起死回生”。不用不知道,一用吓一跳,效果非常明显。

  第一次看到SmartDeblur的效果图我有些惊呆,图片模糊应该是一个不可逆的操作啊?看软件的作者是怎么说的:
Many people think that blurring is an irreversible operation and the information in this case is lost for good, because each pixel turns into a spot, everything mixes up, and in case of a big blur radius we will get a flat color all over the image. But it is not quite true—all the information just becomes redistributed in accordance with some rules and can be definitely restored with certain assumptions.

  讲得比较专业,也比较难翻译,我们不管了。本站提供SmartDeblur 1.27绿色版,这是目前最新版本。下载打开后会有一张示例图片,并且告诉您怎么调节使它变得清晰。SmartDeblur支持三种模式,一是Out of Focus Blur,就是失焦,拍摄时对焦失败;二是Motion Blur,运动模糊,也就是拍摄时抖动了;三是Gaussian Blur,高斯模糊,这个有点专业,不懂的话去找维基百科或百度百科,有详细的说明。

这是一张软件自带的示例图,极其模糊。操作方法如下:

The process is simple. First, you choose the defect type that you’re working with: out of focus, motion blur, or Gaussian blur. Next, you drag the Radius slider until the details you want come into focus. Finally, you drag the Smooth slider until you arrive at your desired quality.

操作过程很简单,首先,你可以选择,你正在使用的缺陷类型:失焦,运动模糊,高斯模糊。接下来,您调节半径滑块,直到你想要的细节都成为关注的焦点。最后,您可以滑动“平滑”滑块,直到到达您想要的质量。

SmartDeblur官网的帮助说明:
High speed. Processing a 2048*1500 pixel image takes about 300ms in the Preview mode (when adjustment sliders can move). But high-quality processing may take a few minutes
Real-time parameters changes applying (without any preview button)
Full resolution processing (without small preview window)
Deep tuning of kernel parameters
Easy and friendly user interface
Help screen with image example
Deconvolution methods: Wiener, Tikhonov, Total Variation prior

其实大致就两点:
1、处理速度快。2048* 1500像素的图像处理需要约300ms预览到处理后的效果。但高品质的处理可能需要几分钟;
2、每种调节都可以时时预览。
