平衡接缝图像之间的对比度和亮度 [英] Balancing contrast and brightness between stitched images

问题描述

我正在开发一个图像拼接项目，我知道处理图像的对比度和亮度有不同的方法。我当然可以在我甚至缝合图像之前处理这个问题，但是结果是不一致的，我希望。所以我的问题是，是否有可能通过任何机会平衡或平衡在彩色图片的对比度和亮度发生后？

I'm working on an image stitching project, and I understand there's different approaches on dealing with contrast and brightness of an image. I could of course deal with this issue before I even stitched the image, but yet the result is not as consistent as I would hope. So my question is if it's possible by any chance to "balance" or rather "equalize" the contrast and brightness in color pictures after the stitching has taken place?

推荐答案

您想要确定直方图均衡功能，而不是从整个图像，而是在他们将接触或重叠的区域。你显然需要在重叠区域有相同的直方图，所以这是你计算函数的地方。然后，您可以对整个图像应用均衡功能。如果您有两个以上的针迹，您仍然希望预先进行全局均衡，然后使用重叠均衡功能的加权应用，在您移动离开接合边缘时减少影响。

You want to determine the histogram equalization function not from the entire images, but on the zone where they will touch or overlap. You obviously want to have identical histograms in the overlap area, so this is where you calculate the functions. You then apply the equalization functions that accomplish this on the entire images. If you have more than two stitches, you still want to have global equalization beforehand, and then use a weighted application of the overlap-equalizing functions that decreases the impact as you move away from the stitched edge.

如果这一点对你已经很明显，道歉，但你的一般问题让我得到一个一般的答案。

Apologies if this is all obvious to you already, but your general question leads me to a general answer.
