平衡拼接图像之间的对比度和亮度 [英] Balancing contrast and brightness between stitched images

问题描述

我正在做一个图像拼接项目，我知道处理图像的对比度和亮度有不同的方法.我当然可以在缝合图像之前处理这个问题，但结果并不像我希望的那样一致.所以我的问题是，是否有可能在拼接后平衡"或均衡"彩色图片的对比度和亮度?

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

你想确定直方图均衡函数不是从整个图像，而是在它们将接触或重叠的区域.您显然希望在重叠区域中具有相同的直方图，因此这是您计算函数的地方.然后，您可以在整个图像上应用实现此目的的均衡函数.如果您有两个以上的针迹，您仍然希望事先进行全局均衡，然后使用重叠均衡函数的加权应用程序，以在您远离缝合边缘时减少影响.

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.

如果这对您来说已经很明显了，我们深表歉意，但您的一般性问题使我得到了一般性的答案.

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