Hello,

I'm working on my final year project in which I have captured a picture from a webcam. I'm trying to find the 'red component' of the image.

So I would like to know,

1)is normalizing the image prior to finding the redness a better idea or finding the redness directly from the image without the Normalizing?

2) Normalizing meaning eg:- R/sqrt(R^2+G^2+B^2) . I have followed this step for all the individual pixels.

Awaiting your reply.
