I am using Emgu C#.
I acquire images from my cameras.
I know when there is no saturation (ie a grey-tone image) by looking at the average hue channel of the image. If zero then pretty sure picture taken at night time.
I can also detect how bright an image is by checking the average Luminescence channel.
What I would now like to do is a value for the gamma an contrast of an image.
Now, I know it is the interpretation of this hypothetical gamma and contrast that determines its value within the context of how I use it. But what factors can i use to attempt to put a scale on these values?
Should I be looking at a different Color Space?
