- Hello All!
-
- I was wondering as to what the following formula which obtains the
- corrosponding Grayscale (luminance) of the RGB triplet was called ?
- i.e. what is the name of this formula...
-
- Grayscale = 0.299 * Red + 0.587 * Green + 0.114 * Blue ;
-
- What are the origins or the logic behind specifying these values ?
-
- I have experimented with different values for the same but obviously
- these seem to give me the best results.....
-
- Thanks in advance.
