注册具有不同焦点的图像 [英] registration of images with different focuses

问题描述

我试图编写一个代码，以便对几个图像（来自同一场景）进行图像配准，它们之间的唯一区别就是图像焦点的位置。在我写的代码中，有一个通常的图像注册阶段：提取和匹配两个输入图像之间的相似特征（使用SURF进行提取和相关匹配），以及RANSAC去除匹配错误。



然而，我得到的结果有错误 - 如果在图像的焦点位置之间注册差异很小的图像，可以看到某些模糊和物体收缩。如果图像的焦点位置差异很大，我会弄得一团糟，好像程序试图将图像中的对象强制在一起。



任何人都知道如何改进它？我正在使用AForge，Accord在C＃中编写代码，我也可以使用Emgu-CV，因此如果您觉得有必要/有用，建议我使用这些库中的函数。



先谢谢。

I've tried to write a code in order to do image registration of several images (from the same scene) that the only difference between them is the location of the focus at image. In the code I wrote there are the usual stages for an image registration: Extracting and matching similar features between the two input images(using SURF for extracting and correlation to match), and RANSAC to remove matching errors.

However, the result I get has errors in it - In cases of registering images with small difference between the images' focuses location there can be seen some kind of blur and shrinking of the objects. In cases with big difference between the images' focuses location I get a total mess, as if the program is trying to pin force objects in the images on each other.

Anyone has an idea how to improve it? I'm writing the code in C# using AForge, Accord and I can also use Emgu-CV, so you can suggest me to use functions from these libraries if you find it necessary / useful.

Thanks in advance.
