I have a greyscale image which was created from a RGB image using farmula:
0.3 * c.r + 0.59 * c.g + 0.11 * c.b
Now, I want to convert the greyscale image back to the RGB color image close to original as far as possible.
I tried o look for it on the internet, but could not find how to do it. Wikipedia suggests that it is possible but does not explain how.
Could someone please suggest how can I do it.
Thanks in advance.
That is not possible. You’ve taken 3D information, and thrown away 2 of the dimensions. You can’t get them back.
