推荐答案

您可能需要将图像转换为其他颜色空间，例如HSL或HSB.因此，您可以将亮度视为向量的一部分.
从本文开始，它包含完整的c#代码.
要了解色彩空间，请阅读此，或通过Google对其进行查找.

You probably need to convert your image into another color space, like HSL or HSB for example. So your can treat brightness as a component of the vector.
Start from this article, it contains a complete c# code.
To understand color spaces read this, or google for it.

我在AForge中使用了亮度"滤镜
这非常有用

Thank you For Answer Zoltán Zörgő

I Used The Brightness filter in AForge
It is very useful

private void button1_Click(object sender, EventArgs e)
        {
          ApplyFilter(new BrightnessCorrection() , image1);
        }


private void ApplyFilter(IFilter filter , Bitmap x)
        {
            
            x = filter.Apply(x);
            // display filtered image
            pictureBox2.Image = x;
        }
