在iOS中，Deconvolution可用于视频吗？ [英] Is Deconvolution possible for video in iOS?
问题描述
我想拍一个摇摆在棒球上的击球手，但蝙蝠模糊不清。视频是30 fps。
I want to film a batter swinging at a baseball, but the bat is blurry. The video is 30 fps.
通过研究我发现解卷积似乎是最小化运动模糊的方法，但我不知道我是否或如何实现它在我的iOS应用程序后处理。
Through research I have found that deconvolution seems to be the way to minimize motion blur, but I have no idea if or how I can implement it in my iOS app post processing.
我希望有人可以指出我正确的方向，如如何在iOS中应用解卷积算法或我可能需要做什么。 ..或者如果它是可能的话。我想它需要一些处理能力。
I was hoping someone could point me in the right direction like how to apply a deconvolution algorithm in iOS or what I might need to do...or if it is even possible. I imagine it takes some processing power.
欢迎提出任何建议......
Any suggestions at all are welcome...
谢谢，这个令我疯狂......
Thanks, this is driving me crazy...
推荐答案
经过大量研究并与开发人员商讨关于iOS上的去卷积问题（感谢Brad Larson花时间给我详细信息）我相信这是不可能和/或不值得的时间。如果硬件可以处理计算（不保证），它将非常慢并消耗设备的大部分电池。我也被告知可能需要数月才能实现算法...如果可能的话。
After a lot of research and talks with developers about deconvolusion on iOS (Thanks to Brad Larson for taking the time to give me detailed information) I am confident that it is not possible and/or not worth the time. If the hardware can handle the computations (No guarantee) it would be EXTREMELY slow and consume much of the device's battery. I have also been told it could take months to implement the algorithms...if it is possible at all.
以下是我从Apple收到的回复...

反卷积算法通常很难实现，而且计算量很大。我建议你从简单的锐化技术开始。根据视频中运动模糊的数量，它可能就足够了。
Deconvolution algorithms are generally difficult to implement and can be very computationally intensive. I suggest you starting with a simple sharpening technique. Depending on the amount of the motion blur in your video, it might just suffice.
锐化滤镜，包括CISharpenLuminance和CIUnsharpMask，现在可在iOS 6中使用，所以它很容易测试它们。
The sharpen filters, including CISharpenLuminance and CIUnsharpMask, are now available in iOS 6, so it is moderately easy to test them out.
来自今年WWDC会议的核心图像示例代码511核心图像技术。它被称为尝试3。此示例演示了将CIFilter应用于iPhone / iPad相机拍摄的实时视频的最佳实践。您可以从以下页面下载会话视频： https://developer.apple.com/videos / wwdc / 2012 / 。
