推荐答案

图像中的直方图是图像中使用的颜色的频率。图像对于特定图像不是唯一的，并且在其中没有位置信息。许多图像可能具有完全相同的直方图。



因此您无法通过其直方图更改图像颜色。



查找OpenCV，它可能会有所帮助。或者C＃中的Bitmap类允许逐个像素地获取和设置颜色。

The histogram from an image is the frequency of colours used in an image. An image is not unique for a specific image and has no position information in it. It is possible that many images can have the exact same histogram.

So you cannot change an images colours via its histogram.

Look up OpenCV, it may help. Or Bitmap class in C# allows to get and set colours pixel by pixel.
